As long as people have been making wine, vinegar has also been made. Actually, wine is just a stop along the way on the path between fruit and vinegar; one could say that vinegar is what wine ultimately wants to be. But while we pay tremendous attention to the wine stage, the fantastically nuanced end-stage is all too often ignored or dismissed as uninteresting. You got your basic vinegar (white or red) and you got your balsamic vinegar – what’s the big deal? Well, gentle reader, read on!
Anything that can be made into alcohol – fruits, grains, rice, tubers, etc. – can be made into vinegar. The sugars ferment and turn into alcohol that, left unchecked, turns into vinegar. This is because of an exceptional bacteria –
acetobacter – that uses oxygen to metabolize alcohol, gobbling its way through an bottle of wine, for example, and converting the alcohol into acetic acid and water (vinegar). Annoying though this can be if you’ve had a bottle of Chateau Margaux 1995 turn undrinkable, in the Big Picture it’s a fine thing because vinegar has been very helpful to human history: its acidity makes it a very effective antimicrobial agent and storing food in vinegar (pickling) is one of the best food preservatives ever discovered. In addition to its healthful benefits, acetic acid contributes two flavor elements to food: a bracing acidity on the tongue and a startling pungency in the nose. Yum!
Although it’s a natural process that can happen quickly, the best vinegars are made slowly and may be aged for years before they are considered usable. True balsamic vinegar* is aged a minimum of twelve years before it can even be evaluated; good sherry vinegar is always a blend made over many years. There are three ways that vinegar is produced (one very good, one tolerable, and one awful):
• The Long Time in Barrel method, which includes both the Orleans and Solera styles. Here, wine is kept in barrels over months or years. The barrels are partially full, which exposes the wine to oxygen and natural heat/cool cycles of weather. In the Orleans method, the vinegar stays in one barrel for several months; in the Solera method, the vinegar is shifted through a series of barrels over time, blending younger vinegar with old, and old vinegar with older. Either of these methods takes two to six months to turn wine to vinegar, and the vinegar is often aged for years more.
• The Keep it Moving method, where wine is kept flowing over wood chips that have been inoculated with acetobacters. The conversion takes about a week.
• The Submerged Fermentation method in which oxygen is forced through the liquid (grain alcohol or wine) in a sealed tank. This takes a few hours.
You can’t hurry good vinegar any more than you can hurry love. The good stuff takes time. Slow development allows for layers of flavor; exposure to seasonal weather cycles affords the vinegar time to change (in warm months) and to rest (in winter), aging in wood mellows the flavors. And, as with so many things, the quality of the finished product can never be better than the quality of the raw materials. Crap wine makes crap vinegar, there’s no way around that. And good fruit vinegars (e.g. – raspberry or apple cider) always start with a wine that has been made from the fruit. Don’t fall for the ‘raspberry infused’ stuff – that’s often just cheap vinegar that somebody stuck some raspberries into: it may be pink, it may smell and taste a little like raspberries, but it’s nothing like the refreshing, nuanced vinegar made carefully from raspberry wine.
With good wine vinegars (as opposed to fruit, malt, rice, or grain vinegars), the label should clearly state what kind of grape it is made from. For example, we currently have vinegars made from Barolo, Pinot Grigio, Cabernet Sauvignon, Banyuls, Gruner Veltliner, etc. These vinegars carry forward the characteristics of their parent wines, and will bring those flavor and aromatic notes to any dish. If the label just says “red wine” or “white wine” it is likely made from the cheapest sort of plonk. This stuff is fine if the vinegar is a very minor player in a recipe (like a half teaspoon to a couple of quarts of sauce or soup), but if it’s a serious partner with the other ingredients – in a vinaigrette or gastrique, for example – use a vinegar that tastes good!
If you’d like to learn something about the different flavors of vinegar, have a little taste test. If you have a few vinegars at home, great. If not, come into the shop -- we always have several bottles open for tasting.
The first thing to do is smell the vinegar. Don’t take a big sniff as if you are tasting wine, try just a couple of gentle little whiffs. Think about what you get beyond the pungent notes. There could be floral, woody, fruity, leathery notes, and so many others – just like wine, cheese or chocolate.
Then have a little taste. Sure, it’s not always easy to pick up the nuances of flavor when your mouth puckers up from the acidity, but there are a couple of ways around that: 1) Dunk a sugar cube into the vinegar and then quickly suck on the cube. The sugar will help keep your taste buds open to the other flavors (you just have to mentally separate out the sweet components from the other flavors; or 2) Dip a little bit of bread (anything but sourdough) into the vinegar and then eat that.
Taste and compare a few, and you may be surprised at how different they can be! Banyuls vinegar is light and delicate, sherry is nutty and raisiny, Gruner Veltliner has pineapple and tropical fruit notes. Blueberry vinegar has a rich sweetness, and Tomato has a bright, lively kind of salinity. Let your imagination roam while your tasting – try pairing these flavors with other foods and see what you come up with. How about venison marinated in blueberry vinegar? A splash of sherry vinegar in a simple tomato soup? A hint of tomato vinegar to brighten up a caprese salad?
Vinegar is a wonderful partner to many foods. Invite the good stuff to your table – you may be surprised what excellent company it offers.
