This is AWESOME!!
I found it at BrykMantra. It is a fabulous idea and fun party game! These guys took cheap vodka and filtered it through a Brita filter to see if it improved the taste to the level of Ketel One. Low and behold, it did! Vodka is traditionally filtered through charcoal filters, and well, duh, Brita is a charcoal filter! As one of the commentors suggested, WHY DIDN’T WE THINK OF THIS IN COLLEGE!!
This would be fun to try!
