The various calculators provide the amount of priming sugar for a specific brew but it does not provide how much water. Some people use 2 cups, some less. I used 3/4 c water (bottled) plus the amount of priming sugar specified in the calculator. I added the sugar and brought the water to a boil. I let it boil a few minutes then cooled and added to my bottling bucket. I mainly do small batches, 1 to 1.5 gallons. Is 2 cups water the norm for a 5 gallon batch? If so, then one would use less water for a smaller batch, correct? Also, lets say I am bottling 1.5 gallons of x beer and the calculator says 33 grams corn sugar. If I use 1 cup of preboil water volume plus the sugar and boil for 10 minutes, the yield would be less than 1 cup of sugar water. How would that smaller volume affect the carbing of the beer? Do I even need to boil the water for 10 minutes? Sorry for all the newbie questions but the posts I've read do not mention anything about water volume for smaller batches so when I bottled my last brew, I boiled 3/4c water. I have tried a couple of bottles and they carb level was fine.
