A lot of what I have is home made. I purchased 6 gallons of Pinot Noir grape juice from Yamhill Vineyards about 4 years ago and made my own version of their Pinot Noir. I still have about a dozen bottles of that left in my wine rack. I also have a 48 bottle wine cooler that my wife got me for Christmas one year. It is about 2/3rds full of 90+ point (scored by Wine Spectator) wines in a variety of types and vintages. I always have just the right wine for any dinner party that my wife and I throw.
My favorite is a wine called Frost Fire from Breitenbach Winery in the Amish Country of Ohio. It's like drinking a white grape with frost on it. Sweet, clean and spectacular. I'm a dry wine fan for the most part, but this stuff is my favorite.
I always have some kind of specialty microbrews in the fridge too. In the liquor cabinet we have Jack Daniels (My wifes favorite), SC, Gin, and Frangelica. I love a small snifter of Frangelica on ice after a steak dinner.
We don't drink much though. We have plenty of alchohol, but don't drink very often. Maybe one drink a week for me and one every other week for my wife.
Now, in my younger days, it was common to have a couple of beers every night, but not anymore. I only purchase beer in six packs, unless I'm having a party. If I were to buy a 12 pack, it would last for 3 or 4 months.
