I'm rather new at this. I've brewed a half dozen or so batches with no complaints. I've been priming 5 gallons with 3/4 cup of corn sugar as per Charlie Papazian's "New Complete Joy of Homebrewing". But I've since seen discussions about priming rates and used the Bottle Priming Calculator on TastyBrew.com (TastyBrew.com | Homebrewing Calculators | Botting Priming Calculator)to see what I should use to bottle my next batch (which is an ESB). The calculator is telling me to use .5 oz for 5 gallons! That is no where near 3/4 cup. Is an ESB supposed to be that flat? Am I putting in wrong numbers? It's asking what temp I fermented at, which is 70* F. I'm cunfused.
