Trockenbeerenauslese (literal meaning: "dried berries selection") is a German language wine term for a medium to full body dessert wine.
Trockenbeerenauslese is the highest in sugar content in the Prädikatswein category of the Austrian and German wine classifications.Trockenbeerenauslese wines, often called "TBA" for short, are made from individually selected grapes affected by noble rot, i.e. "botrytized" grapes.
This means that the grapes have been individually picked and are shrivelled with noble rot, often to the point of appearing like a raisin. They are therefore very sweet and have an intensely rich flavor, frequently with a lot of caramel and honey bouquet, stone fruit notes such as apricot, and distinctive aroma of the noble rot. The finest examples are made from the Riesling grape, as this retains plenty of acidity even at the extreme ripeness. Other grape varieties are also used, such as Scheurebe, Ortega, Welschriesling, Chardonnay, and Gewürztraminer and many are more prone to noble rot than Riesling since they ripen earlier.
These wines are rare and expensive due to the labor-intensive method of production, and the fact that very specific climatic conditions (which do not necessarily occur every year) are required to create botrytized grapes. Some of the best wines of this type are sold almost exclusively at the various German wine auctions. They are usually golden to deep golden in colour, sometimes even dark caramel. The body is viscous, very thick and concentrated, and arguably can be aged almost indefinitely due to the preservative powers of its high sugar content. Although TBA has very high residual sugar level, the finest specimens are far from being cloying due to high level of acidity.
