I see lots of posts talking about less than 6 cups for a 5 gallon batch, but I'm having a hard time with what it tastes like based on the recipe. Maybe I've got a bad batch or it's my taste buds, but with 6 cups, it just doesn't seem sweet enough and I barely taste the lemon.. So I'm thinking about adding more sugar. How many of you have tried more than 6 cups for a 5 gallon batch? Would it be crazy to go to 2 cups per gallon? Thanks!
