Trockenbeerenauslese wines, or TBAs, are generally made only a few times a decade, and in very small quantities. TBAs are a specialty of Germany, and—to a lesser extent—of Austria. Among the world’s greatest sweet wines, TBAs are low in alcohol but high in acidity and residual sugar, giving them incredible balance. It takes one person a full day to select just the right concentrated, botrytis-infected grapes that will become a single bottle of TBA. The resulting wine is absolutely mesmerizing in its intensity and balance (and it’s expensive).
