First, let me say that when you are making homemade gin, you are most likely making a compound gin not a distilled gin. You can read more about the difference between the two here at Serious Eats. I like to be honest and call mine "gin flavored vodka" because that's exactly what it is. In point of fact, all gin is basically flavored vodka, but you can read more about that from Jeffrey Morgenthaler.
PLEASE DRINK RESPONSIBLY
