Sherry and red wine vinegar are the backbone of a good vinaigrette, a gazpacho, or a pan sauce, and the commodity versions are harsh, one-note, and fermented fast for volume. Real wine vinegar is fermented slowly from actual wine and aged in wood, which rounds off the sharpness. These two American makers barrel-age theirs the slow way.

A New England vinegar house working out of a historic mill, slow-fermenting and barrel-aging its vinegars and bottling them raw by hand. Their California sherry vinegar is double-barrel-aged and nutty with high acidity; the red wine vinegar is made from California Shiraz and oak-aged for real wine character. They rebuilt 1800s-design vinegar equipment with local universities to do it.
Why it isn't on AmazonSlow-fermented, double-barrel-aged sherry vinegar bottled raw is a craft product — commodity wine vinegar is fermented fast in tanks and stripped of exactly what makes this taste good.

A small family operation whose vinegars turn up in serious restaurant kitchens around the country.
Why it isn't on AmazonEstate wine vinegars aged in barrel by one family are made on a scale and a timeline a commodity vinegar plant would never accept.

Add your brand →Its nutty, slightly sweet depth makes it the classic acid for a Spanish gazpacho, a sharp vinaigrette, sautéed mushrooms, roasted vegetables, and pan sauces where you deglaze at the end. It's more complex than red wine vinegar, so a little brightens a dish without tasting purely sour. Start small and taste.
Both are wine vinegars, but sherry vinegar is made from sherry (a fortified Spanish wine) and barrel-aged, giving it a nutty, rounded, almost caramel edge. Red wine vinegar is brighter, fruitier, and sharper. Use red wine vinegar for everyday dressings and marinades; reach for sherry when you want more depth and complexity.
Time in wood mellows the raw, harsh acidity you get from fast tank fermentation and lets flavors develop, the same way it does for wine or whiskey. A slow-fermented, barrel-aged vinegar tastes rounder and more layered. Commodity vinegar is made quickly for yield, which is why it can taste like a slap of sourness and not much else.
Raw, unfiltered vinegar keeps the living cultures and some sediment (sometimes a wispy 'mother'), which many cooks feel gives fuller flavor. It's harmless, and you can shake or strain it if you prefer. It's not automatically superior to a well-made filtered vinegar, but with a craft producer it usually signals minimal processing.
