As you probably figured from the thread you referred to, you have me on board with the wine

Over the past years my wife and myself also became increasingly interested in trying all kind of different wines.

Usually it's 2-3 bottles per week as me mostly drink wine during the weekend for dinner (more of course if we hace guests) and currently there are 100+ bottles in the cellar - which is actually a bit too much as our cellar does not really provide the best conditions to store wine over a longer period of wine.
We's like to start properly storing wine, but a real wine fridge would be awfully expensive.

It's hard to point out favourites - personally I like Pinot Noir very much (especially from the Bourgogne but we also have some pretty decent Pinot Noirs here in Germany), but overall we prefer the variety and play around with food/wine combinations.
For white wine our "mainstay" is naturally Riesling - we have a very good winery in the area from which we buy some boxes each year - but again, variety is important.

Tasting (and buying) some wine was also an additional motivation for our vacation in France in September where be bought a couple of bottles from the Alsace, Bourgogne and Rhone - some of which we will try when we have some friends over for dinner this weekend
