that blantons tiki looks like a little grenade!
i keep a few screw-cap bottles around and put home made drinks in them. great for refilling with homemade limoncello made with vodka and everclear, and tossing them in the freezer. I also rebottle homemade apple cider/sugar/cinnamon/clove/bourbon for storage or gifts
most stuff just goes into the recycle bin though.
the angels envy bottle would make a cool vase as someone above mentioned.
I've taken empty BTAC bottles and filled them with black aquarium rocks to help white labels stick out.... Make great book-ends on the shelf.
Most go in the trash, But i made a candle out of an old bottle of makers mark. filled it with water, red food dye, red candle in the top, with extra wax dripped over the wax that is already there. Wish I still had a picture of it
I recall a guy doing something like that with wine bottles but he was making candle holders.
BTAC bottles make the best Molotov cocktails.
Small bottles (less than 750ml-4/5 qt) for decanting contents of larger bottles that have been partially consumed. Everything else recycled. When you have 100+ full bottles it's hard to keep empties. One or two for candles. I have a 1949 OT BiB bottle for that purpose, though the top broke off partially.
I keep one of every bottle I've had as proof I'm not talking out my a** when I make an opinion on a whiskey. After I have one bottle saved, the rest get recycled or donated to my friend's dad. He melts them and makes wind chimes out of them.
If you have anything Michter's or Pennco and would like to sell it or share it with me, please let me know.
