I used these for the first time last night on an English mild, and I sure they will work great. However, the package didn't explain anything beyond the number to use for a desired carbonation level. (I used 3 per 12 oz bottle to get mild carbonation) Is there a general rule of thumb when using these? I didn't know whether it would be better to crush them first, shake the bottles a bit, or just leave them to break down naturally. I'm interested to hear other people's opinions on this topic, and if it helps I have about 12 days for the to bottle condtion before an upcoming competition.
