I can't seem to find where this question has been previously addressed here, so here goes. Several years ago during the holidays I purchased some Seagrams whiskey in plastic bottles. I prefer glass bottles, but I didn't think much more of it then as the store only had plastic bottles and I had planned on giving these away as gifts very soon. Well, I still have them unopened, and I was wondering, does the whiskey break down the plastic causing the whiskey to taste bad or become undrinkable after a period of time, or does plastic hold up as well as glass? Thanks for your input.
