I like extremely offensive ginger ale and this is my attempt at one... Toyed with adding serrano and lemmon grass, but this is my first try at a soda so better keep it mellow...
2.5 gal water
2 cups grated ginger (I smelled the three they had at the SE Asian market and picked the strongest one), tightly packed
3 cups cane sugar
1/2 cup blackstrap molasses
4 lemons juiced and zested
1/8 tsp Jamaican allspice
1/8 tsp cardomom
1/4 tsp grated nutmeg
1/4 tsp cinnamon
Brought water, sugars, juice, and ginger (ginger and zest in a tight mesh bag) to a boil. Flameout, add spices and cover. Steep for 30 min, pull solids and cool (it's snowing in Denver and I am working from home, so a water/snow bath is what it got). Once it got to 40F, I kegged at 50 psi and shook for 5 min. Will leave at 50 overnight, then drop to 25 and see how it is in the am.
The taste is great... just enough of the molasses to be rich and dark, but not too overpowering. The spices are pretty nice, but not integrated yet... probably better colder. SWMBO tasted it and immediately told me to add a gallon of rum or vodka to the keg...
I think we will try this as is and then toy with mules on tap after!
Will report Wed or Thursday...
