Gin is better than rubbing alcohol.

6. Isopropyl

It was the only kind at the store.

Also, I wanted to make a full gallon of 11-to-1 mix and it's possible I erred too much on the side of caution when masuring out the amounts. Making a gallon in the way I did made the math more complicated-- I started with a store-bought gallon of spring water b/c I didn't have any empty gallon jugs and had to remove two cups to leave room for the RA and then calculate the ratio.

I also realized last night that the Cornell article says the liquor-to-water ratio should be one-to-seven, not one-to-eight (I got that in my head from a blog that linked to the CU paper), so all my gins were one-to-eight and it still worked fine. The CU paper does say that anywhere from a 4-6% solution works. Guess I proved that.
