I live in Connecticut, and it's been in the 90's for the past bunch of days, my basement is half underground and was at about 60 when the heat wave started. Now it's about 70. I'd recommend Always keeping your bottled beer in the basement, that's what I do since I don't have a cellar. It's always the coolest part of my house, and will have to do until I have a place of my own with an actual cellar. I don't think it'll cause any damage to my beer since the temp increase is slow & gradual, and never really above 75.
No clue about apfelwein though, I've yet to make it myself (but not for long).
