When I started drinking wine, I thought (as many do) that red wine came from red grapes and white wine from white grapes. Let's have a look see. Here's a picture of some ripe cabernet sauvignon grapes:
And here are some ripe sauvignon blanc grapes:
The color of wine has little to do with the color of the grape. If a winemaker wishes to make a red wine, the skins of the pressed grapes stay in the fermenter with the juice. The alcohol produced acts as a solvent, drawing color from the grapes. This process is called maceration. Grape skins are not present in the fermentation of whites. (Rosés are made by leaving the skins in briefly, yielding a "less red" color.) Since tannin also comes from the skins, white wines tend to be less dry and have more fruit flavor than reds. Tannins also act as a preservative, which is why -- as a rule -- it's better to drink whites and less tannic reds young, while cabernets can age for long periods of time.
As I mentioned before, there are three major white varietals: Sauvignon Blanc, Chardonnay, and Riesling. And, as before, pick up a bottle of each of these varietals, pour a little, and taste them in this order.

First, Sauvignon Blanc. Sauvignon blanc likely originated in the
You'll immediately taste the acidity on the first sip. Many SB's have a very pronounced citrus flavor. Some also have a mineral character -- and we'll get to that when we explore sauvignon blanc in more detail. The finish is usually tart and crisp. On a hot day either after working outside or sunning poolside, there are few more refreshing choices than sauvignon blanc.
Sauvignon blancs are incredibly food-friendly because of their high acidity. Much as a cabernet sauvignon's tannin allows it to cut through the fat of a piece of red meat, the makeup of a sauvignon blanc allows its flavor to stand up to many other foods. Spicy foods like Mexican, Indian, or Thai go well, as would a simple salad. (Salad, honestly, is one of the more difficult food pairings.) Light fish dishes also go well, as the sauvignon's flavors won't overwhelm those tastes.
On to Chardonnay, the most popular white varietal in the world. Why? In my opinion, there's more variation in taste among chardonnays than almost any other varietal, red or white. Thus, there's a "flavor" of Chardonnay for almost any palate. In general, Chardonnay generates a full-bodied white wine, less tart than the sauvignon blanc. The fruit is less pronounced, and the finish tends to be smoother.
As for that variation in flavors, if you ever hear discussions of "old world" versus "new world" wines, Chardonnay is a classic example. Old World-style chardonnays (such as white Burgundies) tend to be slightly acidic and crisp. The fruit flavor tends to be mellow, pleasant, and refreshing. New World Chardonnays (specifically,
The "butter" flavor comes from a process called malolactic fermentation. This bacterial process converts the very tart malic acid into lactic acid. Lactic acid is not as tart -- it's the same acid found in dairy products. The result of malolactic fermentation is a compound called diacetyl, which has the aroma of buttered popcorn. If you hear someone referring to a wine "undergoing full malolactic fermentation," that's longhand for "this wine won't be very tart."
The "oak" flavor is unmistakable. Many
The Rabbit Ridge I used is very much a "
Because Chardonnay has so much variety, you can find a specific one to go with any number of foods. The Old World chards go really well with seafood, while the
Finally, Riesling. Many people's thoughts of Riesling don't go far beyond the mouth-puckering sweetness of
I did an extensive entry a while ago on Riesling, so if you want to know your spatlese from your kabinett and your trocken from your halbtrocken, go here.
The Selbach is a "Qualitätswein" -- the German designation for basic table wine. You'll notice a fairly strong apple scent when you swirl. The taste will be "round" and full with a pleasant sweetness. The sweetness will be even more evident next to the other two wines. You'll also get a little bit of acidity on both the taste and finish.
Like sauvignon blanc, Riesling is an exceptional food wine. Thai or Chinese food go remarkably well with Riesling, but traditional German and Austrian cuisines work well here, too. If you're ever at a loss for a bottle of wine to take to dinner, buy a Riesling, specifically a "dry Riesling" (the label will either say "Dry Riesling" or "trocken"). Dry Riesling pairs with anything from sushi to bratwurst.
One final note: Although there's no absolute consensus on the order in which you taste wines -- I tend to taste drier wines before sweet wines, and light wines before heavy ones. A sauvignon blanc will taste better before a chardonnay, rather than the other way around.
I'd suggest you do a couple of these "varietal side by sides" so you can tell the difference among grapes. The next several "lessons" will deal with the varietals individually. First up will be pinot noir.
Until next time…class dismissed.
