1 cup/gallon is just what I’d recommend for a first batch.
I was thinking that weighed 1/2 pound but I see it weighs .44 pounds. No problem, us noobs don’t have to worry about being off by 10%!
I use about a cup and a half depending on my mood.
What yeast are you using, are you using a carboy, and how big a batch are you making?
I have a 5-gallon plastic carboy, so I am making 5 gallons. The yeast is Wyeast for cider and mead.
