I was talking to a co-worker about different liquors and we were talking about different vodkas, he said take the vodka that you like and pour it in a shot glass straight up, than take another shot glass and b4 you pour your vodka run it thru a coffee filter. try both of them, purpose to see which one is smoother & better tasting. i have to try this, as he says that not only will it taste better but you will deff get all of the impurities out, which it makes sorta sence. my liquor of choice at the moment is rum, don't think space carries any top shelf rum so i just stick to bacardi which i know its low grade rum, but its better than nothing.
