About to bottle my third batch but I don't have a scale to weigh out my priming sugar. A guy lent me his but I don't think I did it right on batch number two... We don't speak of batch number 1. I don't think I weighed out enough sugar for number 2. Beers a little flat. If i stir it up with a spoon i get some action on the head but not much. On my own this weekend and need a quick fix to figure out how much sugar to use. If I'm supposed to use 4-5 oz for 5 gallons (right?) how can I convert that into measuring cups? I know this is not the proper way to weigh but im in a pinch!
