Does this smell funny? / A pesky yeast causes a stink

Via SF Gate

Almost everyone agrees that a little Brett is not a bad thing. It’s generally less of a problem in white wines, and at low levels it can give some red wines cedar, tobacco or cigar-box aromas, scents frequently used to describe Cabernet Sauvignon and generally thought of as pleasant. It also mutes some of the fruitiness of youth, making the wine seem more mature and complex, at least in the short term.In other wines, or in greater concentrations, the smell becomes more leathery and animal-like, evoking adjectives such as horsey, wet horse blanket or sweaty saddle. Although some people can enjoy these smells, many find them unattractive.

At their worst, Brett aromas turn medicinal, reminding many tasters of the inside of a metal Band-Aid box. The animal scents get funkier, more barnyard-y.
