Some friends opened a bottle of an Italian wine that had been imported by a favorite California winery. This is to say, we didn’t know the wine but we trusted its source. It was a red varietal we hadn’t heard of. Nevertheless, it had a smell and a taste that your Two Wine Nuts were familiar with.

So what does that Band-Aid taste and smell mean? Band-Aids is a tell-tale sign of a very specific yeast hanging out in a wine. It indicates the presence of a yeast called brettanomyces [breht-tan-uh-MI-sees] – or “brett” for short. Brettanomyces is a yeast that grows naturally on grapes and in wineries. For the most part, wine makers try to avoid allowing brett into their wine. However, there is some debate among winos as to whether or not a brett-flavored wine is a good thing or a bad thing. A little brettanomyces in a wine can add some complexity and earthiness, especially in a red wine. However, too much brett and you start wondering who has the boo-boo and just opened the Band-Aids box.
