Everclear has absolutely no odor other than pure alcohol. It left me with no after-taste and no hangover. It's made with corn.
Gem Clear, while it is slightly cheaper, leaves me with a Vodka-like aftertaste, a terrible hangover, and a day with a mildly upset stomach. I can't find information on what's it's made with. I'm guessing potatoes.
The upside of this is a loss of appetite because alcohol has 7 calories per gram.
Typically I mix 50 ml of the alcohol with 50 ml of Margarita mix over ice in an 8 oz glass, then top it off with water, or tonic water. Under normal conditions, you should only use about 25 ml of the alcohol, which would match a normal Margarita's alcohol content.
You can stretch your alcohol budget very far with cheap, pure alcohol, instead of buying expensive brands of Vodka or Gin. Basically about half the price.
