While many tend to think that an Auslese Riesling is sweeter than other styles, this is not always the case. Auslese directly translates to ‘selected harvest' which is often done late in the season when the grapes have a high concentration of sugars in them (in fact, the sugar content of the grape is how the categorization works outright).
But sugar in the grapes does not necessarily translate to sugar in the glass. Some producers may ferment the sugar out while others (in our experience, the vast majority of others) may stop fermentation early to leave some residual sugar in place for you to enjoy in your glass.
Dr. H. Thanisch's Bernkasteler Lay Riesling Auslese is in the latter category and offers up both a sweet and complex German Riesling that we cannot get enough of.
