So I was in Houston a couple of weeks ago to attend the Astros/Angels series. I stopped by Spec's and picked up 2 bottles of Angel's Envy Rye. I put them in my trunk and sort of forgot about them till I got home the next day.
Well it gets hot in Texas and my trunk must have been over 125 degrees.
When I opened the trunk to get my bottles out I noticed the sweet smell of the bourbon. I had both bottles inside a soft sided cooler. One of the bottle's cork had popped off, thankfully it was sitting straight up so I did not lose any juice. The other bottle was fine. Angels Envy only uses a paper seal on top of the cork, so it did not take much pressure to tear that off.
So I did learn a lesson, keep my bourbon cool and out of a hot trunk.
