I like this one personally, no math required:http://hbd.org/cgi-bin/recipator/rec...rbonation.html
FYI, the carbonation per style recommendations are a little off (IMO). It's still a great calculator
, just plug-in the # of gallons, temperature and desired carbonation level. Output provided in Grams or Ounces of Corn Sugar, Sucrose, DME or Honey - you do weigh your bottling sugar before adding don't ya?
p.s. Did anyone else notice the zombie revival? Must've been a full moon or something.
