I tend to keep them several years and often use them as aperitifs. If I serve them with food, I have them with Oriental food or even with ham. I had a '93 Rheingau Auslese with a dish consisting of chicken thighs, soy sauce and honey. The match was excellent. How do you use yours at table?
I would avoid that because you don’t want to have the two sweet things competing. There’s a real danger the wine will taste lousy. Maybe with unsweetened fruit, but conventional desserts are dangerous with sweet wines. A relatively unsweet almond or walnut cake is a good foil, though.
As Auslese dry out, they can work wonderfully with smoked fish of any sort. Or as an aperitif.
The ones from Weil, AJ Adam, Catoir or basically anything from 2006 - treat as dessert wines and drink them after a meal.
Among the lighter/botrytis-free Auslese (from the likes of Kruger-Rumpf, Grunhaus, Selbach, Christoffel) - if younger, I’ll open them with moderately spiced food (North Indian, Szechuan, Thai). With older ones where the sweetness has started to fade, I’ll try and pair them with a relatively simple meal (pork tenderloin, roast game birds) that’ll allow the wine to take center stage.
I have them when I’m having “snack” type things. Like smoked duck breast, a few cheeses, maybe some sausage, maybe some duck or goose liver, etc. That ends up being supper many a night and sweet wines go really well with those things.
