Sucker for a good craft beer (I prefer hazy IPA's in particular), I live about an hour from Treehouse Brewery so every once in a while me and the roommates will pitch in and get a case or two. Being broke 20 somethings though, not something we do too often hahaha the typical beer we keep in our fridge is the Sierra Nevada Hazy Little Thing, good bang for your buck in my opinion!
Also love a bottle of red wine every once in a while. Typically go for the Josh Cellars Cab as my reliable choice
For non alcoholic drinks, best purchase I ever made was a Breville Barista Express. I would waste so much money going out for coffee all the time, figured I should pull the trigger and get myself a machine. Expensive up front, but has saved me a huge amount of money on coffee, and it's pretty fun getting to fine tune my coffee just how I like it
