When I went to Scotland in 2009, I got to visit Duone Castle, which is one of the castles "Monty Python and the Holy Grail" was filmed in. To commemorate the visit, I bought a bottle of Holy Grail Ale. After I poured it out (I know--party foul), I put it on display in the entertainment center I had then, and so started my glass and bottle collection.
After the 2015 Jackson Free Press beer tasting, I took an empty bottle of Rogue Sriracha Ale and New Belgium Brewing Co. Transatlantique Kriek home with me to turn it into another glass for my collection. As I discovered, it's not as easy as it looks.
