My Wine is Too Oaky!

Oak in wine is like salt in food. It may enhance the flavor. But if you can taste it, you probably have too much of it. - A paraphrased but insightful observation of my wine class instructor.

My Oak and I
Oak in wine is indeed a controversial topic. When wine is in contact with oak, aromatic compounds from the oak are introduced to the wine. While there is no accounting for taste, wine geeks often argue about whether a wine is overoaked. That said, many of us are glad that the days of oaky California Chardonnay are behind us.

While there are different types of oak used for barrels (and in fact different types of wood), the two best known are French oak and American oak. Generally speaking, French oak tends to add subtle spiciness and silkiness to the wine while American oak tends to impart a stronger and sweeter flavor that is reminiscent of vanilla.

There are of course other factors that contribute to the influence of oak to the wine. For instance:
  • Toast level - higher toast leads to stronger flavor
  • Coarseness of grain - open-grain barrel releases aromatics sooner, and tight-grain releases aromatics later
  • Barrel size - higher ratio of oak surface area to volume of wine results in more contact
  • Time in barrel - more time in the barrel leads to extended contact
  • New vs neutral barrels - newer barrels have more aromatic compounds

However, an often overlooked benefit of oak barrels is that they introduce a small amount of oxygen to the wine (known as micro-oxygenation) during maturation. Oxygen is critical for the polymerization of phenolic compounds to stabilize the color and improve the quality of the wine. Recent research even suggests that fermenting wine in oak barrels leads to a better quality wine, but that requires another level of maintenance for the wineries.

Now back to the question, when is a wine too oaky? It just depends on how much you like the taste of oak in your wine.

Personally, I find the sweet vanilla flavor imparted by American oak detracts from my enjoyment. I tend to like my red wine silky with nuanced spices and leather notes. I also like older well-made reds and would forgo fruitiness for complexity. In fact, my favorite red wines are often aged in Slavonian oak, known for its tight grain as well as lower aromatics and tannins level. Any guess as to the wine?

My Verdict: If you are like me, you probably prefer the silky soft tannins that result from barrel aging but could go light on the aromatics. Then, depending on the grape varietals, keep an eye out for wine made in French oak (or even Slavonian oak). However, if you like stronger flavors, particularly of vanilla, then maybe American oak is more to your liking. Check out the technical sheet of your favorite wine and see what oak is used and for how long. There's always much to learn!

Cork Taint in a Screwcap?

In my last post, I wrote about the difference between corks and screwcaps, about how the latter has significantly circumvented the problem of cork taint. Then the unexpected happened to me - I got a screwcapped wine that was corked!

One of these was corked
It was a gorgeous summer afternoon in Portland, and I was thrilled to find a new wine bar and bottle shop to try. We sat down at the patio, and I ordered a flight of three mid-range Oregon Pinot Noirs. I swirled the glass of the first wine, took a whiff, and immediately got that faint but unmistaken smell of wet cardboard. I took a sip, which confirmed that off-putting taste devoid of fruit and flavor. I tasted the other two glasses, and they were fine.

I took the corked wine back to the shop and waited patiently for the shopkeeper to finish his conversation with another customer. Then I told him discreetly that the wine was corked. He took it back and came out to the patio with a new bottle and a new glass. He twisted the screwcap off the bottle to pour me a new glass and said, "That wine was fine, but here's one from a newly opened bottle."

Now, I have up to now experienced only half a dozen corked bottles. While it was not a common occurrence to get a corked wine these days, the last three happened in the past year so I am unfortunately quite familiar with the smell and taste of a corked wine; the earlier two being a Brunello and a California Super Tuscan-style red. I have even tried the Saran wrap trick to remove the taint, which, I am sad to report, does not work.

I digress. Now how does a screwcapped wine get corked?

TCA
I mentioned in my last post that the main cause of cork taint is TCA (2,4,6-trichloroanisole), a compound that leads to a musty fungal or wet cardboard aroma.  TCA belongs to a family of volatile compounds called haloanisoles, that cause moldy aroma. There are other compounds (TBA, TeCA, and PCA) that may be responsible for the taint.

Haloanisoles may be transferred to the wine from contaminated materials in the winemaking facility, such as tank coatings, hoses, barrels, and oak chips. It can also be transferred to the polyethylene film, which is commonly used as a liner for screwcaps. So while opting for a screwcap over cork will significantly reduce the chance of cork taint, it does not eliminate it. In my limited sample size, it is one to five.

Here's another interesting factoid - the sensory thresholds of different tasters for haloanisoles may vary as well. So one taster can be highly sensitive to it while another may not find it quite as objectionable. A well-known sommelier once discovered that a rare and expensive bottle ordered at his restaurant was corked. Despite his offer and attempt to replace it with a different bottle, the diners claimed that not only was the wine fine, but it was delicious. At which point, he had to back off against his professional judgement.

My Verdict: Regardless of the closure used, if you believe that your wine is corked, trust your taste and take the wine back. Even if the wine merchant disagrees with you, he or she will likely still replace your wine. It is better than to be stuck with an off-putting wine.

Corks or Screwcaps?

Since the sudden rise of cork taint in the 1960s, the wine industry has been exploded with alternative closures to seal bottled wine. The main cause of cork taint is the presence of a compound known as TCA (2,4,6-trichloroanisole) that leads to a musty fungal or wet cardboard aroma in the wine. While it is not harmful to the consumers, it definitely takes away the pleasure of enjoying a nice glass of wine.

Among the alternative closures with their corresponding pros and cons, the screwcaps in particular have gained quite a bit of traction in the new world, especially in Australia and New Zealand. While I am partial to natural corks for my cellar-worthy wines, summer calls for easy drinking. And who wants to fuss with a corkscrew at a picnic when you can twist the cap off a bottle of fresh Marlborough Sauvignon Blanc and seal it shut again?
Rulo Winery in Walla Walla only use screwcaps 

While screwcaps remain a favored alternative, one common complaint is that it does too good a job
of keeping oxygen out and does not allow the wine in the bottle to breathe and mature. This can sometimes lead to "reductive taint" or the smell of rotten egg in the wine. However, winemakers are getting good at correcting the problem by adjusting the amount of sulphur dioxide added to the bottle prior to closure. (Yes, sulphur dioxide is often added during bottling to stabilize the wine, but that is a topic for another day.)

For cellar-worthy wines, a little oxygen over a period of time helps the wines develop and mature in the bottle. Contrary to popular belief, natural corks do not allow outside oxygen to enter sealed bottles. But because corks are made up of mostly hollow cells, oxygen from the corks themselves is gently and gradually released into the bottles to further age the wine.

As one might expect, the technology of screwcaps has progressed to offer a small amount of oxygen leakage from the cap into the wine, mimicking the same function in a cork. So we may see more and more cellar-worthy wines using screwcaps in the future. In fact, there are some wineries who have gone completely screwcaps for all their wines, including those that you can lay down to age. Rulo Winery from Walla Walla is one such winery.

With a steeper competition for closures, cork producers have also come up with more stringent procedures to reduce the incidences of TCA, like ensuring proper harvesting and treatment of cork. In addition, technical corks (which are essentially cork-based closures) are often treated to prevent TCA and available as less expensive options. In fact, I use technical corks for my homemade wine.

A mix of natural and technical corks
My Verdict: Just as there is a wine for every occasion, there is a closure that fits every type of wine. My rule of thumb is that if you drink your wine young, a screwcap is not necessarily a bad thing. But I would probably pause if I see a screwcapped bottle of Barolo or Burgundy. However, if you trust a particular winemaker, then it may be worthwhile to keep an open mind about his or her choice of closures.

Bonjour, Mon Rosé!

Rosé is a wine of celebration!

Provençal Rosé with fresh spring salad
After a long dreary winter, it is always a joy to welcome sunshine and warmth with a bottle of Rosé. I especially love a dry Provençal or Provence-style Rosé, slightly chilled and shared with friends on the patio, or on the beach. Being light and fruity in palate, Rosés go well with most summer fare - cantalope slices wrapped with prosciutto, spring mix salad with a light mustard vinaigrette, and cheeses. Or if you want to be totally Provençal, pair it with your favorite vegetables and shellfish dipped in rich garlicky aioli.

Rosé is a French term for pink wine, that is well beloved in the States. In Italy, it is called Rosato; and in Spain, it is called Rosado. In a London bistro, I would order a bottle of Blush.

Contrary to some belief, Rosé is not made by blending white and red wines, except in the case of a pink Champagne. But a still pink wine is made using black grapes (or grapes that typically produce red wine) with a much shorter skin contact than one would for making red wine. That way, it significantly reduces the extraction of anthocyanins, or color pigments from the skin, rendering it pink.

To be technical, there are different ways to make Rosés, and they are rather nuanced.
Provence-Style Rosé from Brady Cellars

  • Short Maceration - This is the way to make Rosés with the sole goal of making Rosés, instead of a by-product. In this case, the winemaker crushes the black grapes and macerates them for a period of time. When the desired level of color and flavor is achieved, the juice is drained off from the crushed grapes and continues to ferment.
  • Vin d'une Nuit - This is French for "wine of a night." A simple short maceration approach, it means the juice is drained from the crushed grapes after a night. 
  • Saignée - Derived from the French word that means "bled," this is method is used when the winemaker is trying to kill two birds with one stone. After a short maceration period, the pink juice will be drained out, leaving the remaining juice to continue macerating with a higher ratio of skin contact. The pink juice is then made into a Rosé. The remaining juice will have a deeper color and flavor by the time it is made into a still red wine. This is well-practiced in the States as the Rosé will be released early to bring cash flow to the winery while the remaining red wine continues to mature and age.
  • Doble Pasta - This yummy-sounding approach comes from Spain although it is hardly intuitive. This is similar to Saignée in that a red wine and a pink wine will be produced. The difference is that two vats are used in this case. One vat is used to make a pink wine, and the skins will be transferred to the vat that is used to make the red.
My Verdict: There are different types of pink wine in the market. Pick something and try it. I tend to like a dry Grenache-based Rosé, hence my preference for a Provençal or Provence-style Rosé. And if your favorite small winery for red wine makes a nice Rosé, know that you are helping it by buying a bottle of the pink as well. Santé!

What Makes a High-End Wine?

In the wine world, there are the Two Buck Chucks, and then there are Château Latour or even Domaine de la Romanée-Conti (affectionately known as the DRC). There is a vast price difference between high-end and mass-produced wines, but is there a corresponding difference in taste and quality? Let's consider what goes into a good wine.

Wines of Pauillac
Grapes
High-end wineries are very picky about their grapes. Many will only use grapes from their estate vineyards, where they have complete control on how to grow the best grapes possible. This includes the type of fertilizers used, pest and disease management, canopy management, irrigation (if even allowed), green harvesting, and actual harvesting practices. While controversial, there is the terroir factor - the secret something in the land that gives the grapes or the wine a distinct character. All the above can be costly.

Wineries of mass-produced wines are less fussy about their grapes. Many of them use excess or leftover grapes or juice from other wineries or vineyards. Or they may own inexpensive parcels of vineyards that are not known for quality grapes. These wineries have limited, if any, control or interest in vineyard management. The main goal is to get a large quantity of decent grapes or juice at a low price.

Estate vineyards

Wine Making Practices
Winemakers of high-end wineries are very particular about how they make their wine. Each may differ in his or her own style and philosophy. Some are almost esoteric and minimalist in their approaches. Lalou Bize-Leroy, a firm believer of biodynamic wine making, is almost mystical in the way she guides the evolution from juice to wine. Others apply scientific analysis and use the latest technology to rigorously and meticulously monitor and direct the wine making process. Christophe Perrot-Minot is one such winemaker, who is extremely comfortable with technology and leverages it to produce the best wine out of his grapes.
Cooperage

High-end wineries are also particular about cooperage. The type of oak, grain, toast, and even size of the casks adds flavor, complexity, and mouthfeel to the wine. Some of these wineries even have their own cooperage so that they can control the quality of the barrels.

Makers of mass-produced wine use technology and equipment extensively to produce huge quantities of wine. In fact, these wineries benefited most from the scientific understanding of the wine making process. With more tests and supplements available, the ability to augment lower-quality grapes to produce viable wine has grown exponentially in the last couple of decades.

Add or remove sugar to manage the alcohol level of the final product. Adjust the acid level to achieve the right level of brightness. Use big steel vats that are easily re-usable and less costly and then supplement with oak chips or beans or staves to mimic the wine maturation process that would otherwise happen in an oak barrel.

Consumer's Taste
Ultimately, the difference between high-end and mass-produced wines today is fairly nuanced. If it tastes good and is within your budget, then that is the right wine for you. If you can't really tell the difference but enjoy and are able to afford to drink high-end wines anyways, knock yourselves out and invite some good friends to join you. If you have a palate that appreciates the higher-end wines and your bank account is agreeable, savor an extraordinary bottle. You are blessed!

My Verdict: Personally, I am not a fan of most mass-produced wines. I like my wine to have some complexity in it. Since I also don't drink very much, a nice bottle will last me a few days to a week with my Sharper Image wine saver. Thankfully, the higher-end wines tend to hold up a little longer as well. And when a friend invites me to taste some Bordeaux First Growths, I am most grateful.

Wine Clubs and Member Lists

If you frequent wine country or enjoy winery tours, it is likely that you have been seduced into a wine club membership. The more you drink, the harder it is to resist the temptation.

Truth be told, there are many perks to joining a wine club. There is usually no upfront fee for joining, and you can often terminate membership at any time. You just pay for the wine purchased with membership discount, which is often in the area of 10-20%. The catch is that there is usually a commitment of a certain number of bottles per year and sometimes in multiple releases. Each wine club may vary in the flexibility to mix and match the wines for each allocation, so that is something to which you want to pay attention.

Crates of wine in storage
The other big draw of a wine club is the limited releases that are offered exclusively to club members. This may happen when the winemakers are experimenting with a new varietal, blend, or way of making wine in small production. In other cases, the winery may keep a library of cellar-worthy wines to be released only to its members in later years so as to showcase the aging potential. Finally, there are special events and release parties, when winemakers unveil new releases with amazing food pairings.

If you don't live close to a wine region, check out your local wine shop to see if it offers a wine club. Our local wine shop, West Seattle Wine Cellars, offers six different monthly clubs, ranging from  easy-drinking to region-specific, like Champagne, Washington, and Oregon. The collective buying power from wine clubs allows the shops to have access to certain wines that would otherwise be hard to come by. Additionally, there is a club member's discount for wine purchases.

Then there are member lists. These are often offered by high-end or boutique wineries to give members first dibs on their wines at membership price before they are released to the secondary market. There is no allocation commitment, but members stay on the list as long as they make purchases. A lapse in purchases within a predefined amount of time, typically two consecutive years, may cause you to be dropped from the list. These wineries are usually not open to the public although some offer tours to members by appointment.

Now the danger of wine club and member list memberships is that you can end up with more wine than you need. At which point, it is time to say goodbye to some of them. In the past decade, I have gone through close to a dozen club and list memberships. Today, I am down to two wine club memberships and one member list. Here's the scoop on what I have.

Brady Cellars vertical tasting
Brady Cellars Wine Club
Kim Brady is a friend and fellow West Seattleite, who started his first commercial release in 2010. I'm all for supporting friends and small wineries, and Brady makes it easy by producing excellent wine at an affordable price point. His club commitment is a minimum of 6 bottles a year. Members get 10% off retail price, and the release parties are a blast, not to mention often a stone's throw away from our house. Tyler Palagi of Radiator Whiskey is always whipping up delicious food pairings with Brady's wines.

West Seattle Wine Cellars Specialty Club
I have been a member of the Specialty Club offered by the West Seattle Wine Cellars for several years. It features a red and a white from literally anywhere in the world at a cap of $90 plus tax. But don't worry, Tom DiStefano, who carefully selects each bottle, has never let us down. You may get some interesting selections from Slovenia and South Africa as well as the classics from Barolo, Burgundy, and Rhone. I always recommend this club to anyone who is looking to expand his or her palate.

Quilceda Creek Release Party

Quilceda Creek Private Member List
Last but not least, the exclusive Quilceda Creek Private Member List. Quilceda Creek produces world-class Washington Cabernet Sauvignon and has a few 100-pointers from Robert Parker's Wine Advocate to its name. There is a wait to get onto the member list. It took me less than a year. Once on the list, you get to purchase three of the four wines initially: the Columbia Valley Red (or CVR, which is an excellent deal!), the Galitzine Vineyard, and the Pelanget Vineyard. After another year or so, I was finally invited to the release party and got to purchase the flagship wine. It is a game of patience, but it is definitely worth the while if you are very particular about your wine. All the wines are divine (particularly the flagship), and the membership price is unbeatable.

My Verdict: Depending on your taste and budget, there is likely a wine club or member list that works for you. Unless you have generous cellar space and/or bank accounts, you may need to break up with some club and list memberships that no longer work for you. You can always share wine club or list memberships with friends. It needs some coordination, but it can also be a win-win proposition.

First Vintage

Last October I posted about my first winemaking experience; well at least from crush through the primary fermentation and press. That was probably the most involved part of winemaking, when twice to thrice-daily punchdowns took place with constant measuring of temperature and Brix. That was when the juice was transformed from 'must' to wine as sugar got fermented into alcohol and carbon dioxide.

Secondary Fermentation

After the press, we moved into secondary fermentation of the wine in air-locked vessels. We used a 5-gallon glass carboy and three gallon jugs to use for top-up (I'll get into that later). This period was generally uneventful and less involved, but there were a few things that required attention.

Controlling the temperature. Malolactic (ML) bacteria, which was added to the juice the day before press, were quietly converting tart-tasting malic acids into fuller-bodied lactic acids. ML bacteria are sensitive to numerous factors (e.g. pH, SO2, and alcohol levels), but the one thing that worried me was my ability to keep the wine within the optimal temperature range (>70 degrees). The carboy and gallon jugs were wrapped in blankets, snugged in cardboard boxes, and gently warmed by a heating pad. My biggest fear was stuck fermentation since there were no easy tests to perform at home or measurements to track progress. I resorted mostly to prayers.

Lees left behind from racking
Racking, racking, racking. Even though most of the solid remains of the grapes and yeast (also known as pomace or marc) were removed during the press, there were still some remaining in the wine as it went through secondary fermentation. These are called the lees. Decomposing yeast in wine could cause off flavors. In order to remove the lees, we did multiple racking of the wine during secondary fermentation. Racking is the process of siphoning wine off of dead yeast into new containers.

We siphoned a total of four times; the first time was 24 hours after press, the next two were a week apart, and the final one was a month out.

Racking also has two other advantages:
  • It clarifies the wine. You could literally see that the juice got clearer after each racking. In many cases, clear wine is just a matter of aesthetic. If the wine tastes good, cloudiness may not indicate flaws.
  • When done correctly, racking can introduce controlled amount of oxygen into the wine. During the early part of secondary fermentation, oxygen has positive effects on unfinished wine by stabilizing the color and tannins. It allows the wine to mature gracefully and become more complex. In the later part of the secondary fermentation, caution is needed to minimize oxygen contact. If acetic bacteria is exposed to wine and oxygen, it will turn the juice into vinegar (acetic acid). 
It is important to note that you will lose wine during racking due to spills and as you avoid siphoning lees. The loss of wine during racking may increase the air space between your wine and the airlocks. You can top up the carboy with wine from the jugs or similar store-bought wine (preferably same varietal and AVA). Alternatively, you can add sterilized marbles into your containers to raise the wine level. I personally put some of my top-up wine into a sanitized plastic container, squeezed out as much air as possible, and capped it. It worked!

Final Testing

After more than three months of secondary fermentation, we performed the final testing of our wine to check on sugar, acidity, and ML fermentation. During the primary fermentation, which lasted less than two weeks, I was constantly monitoring and measuring progress. For the much longer secondary fermentation, I really had no idea what to expect. But I was pleasantly surprised by the outcome.
  • Residual sugar was at 0.3%. This was probably the least of my concern since we pressed the wine at a really low Brix. Residual sugar over 0.6% is a concern for still red wine as it may cause re-fermentation in the bottle.
Measuring residual sugar in the wine


  • pH was 3.78. This was slightly higher (or less acidic) since harvest, which was at 3.53. But it was still within the normal range.
  • Titratable acidity (TA) was 7.3125. TA measures the amount of total acids and was higher than our reading during harvest, which was 7.125. It was a bit higher than I like, but not bad.
  • ML fermentation appeared to have completed. While not the most accurate way to test the concentration of malic acid, the chromatography test is cost-effective. The solvent used for the chromatography is extremely toxic, and the test takes several hours. After putting dots of wine sample onto a piece of chromatography paper, it was left in a big glass jar with the solvent and the lid closed tight. 
With one exception, most of the wines appeared to have completed ML fermentation. Yellow patches indicated presence of acids. The top row of yellow revealed the presence of lactic acid, which is the goal of the ML fermentation. The bottom row of yellow revealed the presence of tartaric acid, which is also what we expected. Any yellow in the middle role revealed the presence of malic acid, which would indicate that ML fermentation has not completed. This would show that the wine has not stabilized and will need more time for ML fermentation to complete.

Chromatography test revealed that one of the wines still had malic acid
Bottling

Once the wines had passed all the tests, they were ready to be bottled. We got the bottles that we have saved up, cleaned, and sanitized. (We recycled bottles. If you buy new bottles, you can skip the above steps.) Sulfites were added to the wine just before bottling. Sulfites are a preservative and will keep the wine fresh. They are also anti-oxidants and will protect the wine from oxidation.

Corking wine bottles
Finally, five months after harvest and crush, our first vintage was bottled and proudly named Abscession - a joke, as my husband was recovering from an abscess the day of the harvest. Special kudos go to my partner-in-wine, Alisa. That's her work on the label, making an access look classy. The wine will officially be released in the summer, so check back later.

My Verdict: I am having so much fun learning about winemaking. It gave me a greater appreciation for wine. I don't think going commercial is my calling, but I'm planning for my next vintage already!
