Lately there seems to be a lot of attention on using a Brita filter to purify hard booze in order to make it taste better. I just have to say that it works better than you can ever imagine. I ran some crappy tequila through the filter a few times, and the horrible taste is completely gone. Purified tequila just tastes like water with a really strong bite to it. <-------- enjoying a great tasting ceasar that's 50% tequila Just posting it here because we all know that deep down all students are hard core alcoholics.
