Hey as a fellow alchy I am always tryna hide the fact that I'm drinking in public . My hippy aunt gave me this water bottle for Christmas. Its made out of stainless steel and says not suitable for carbonated beverages which means the idea of putting beer in it just got thrown out the window. But what if I put rum, whiskey or vodka into it. Do you think it will be safe and not eat thru the metal. Id assume that it would work like a stainless steel flask
