Nice job to MrsKFC on that Blanton's, in that she was able to salvage the beautiful stopper. I have done similar torches with OF Birthday Bourbons and RHF bottles. The OFBB is a PITA on the bar, but is a great stable platform for this!! I went with copper plumbing pieces
for the top. Didn't trust the cork from not burning on the OFBB (the stopper is entirely made of cork, and didn't think I could successfully drill the RHF. I'll try the Blanton's next. Again, well done!
That really is a great use for those bottles. The copper looks cool and functional.
I've never tried GTS with any sort of soda. Maybe I'm missing out; but I'm OK with that.
