Just a warning, after brewing a 2 gallon batch of cider, you will most likely regret not making a bigger batch...
I know even after a 5 gallon batch is done I find myself wishing it was 10 gallons... Lol
But seriously, any recipe you find can be adjusted for 2 gallons! Just a little math involved. A one gallon recipe, multiply each ingredient by 2, a 6 gallon recipe, just divide by 3, and a 5 gallon recipe, divide by 5 and multiply by 2
