I've practice bottle conditioning in all batches.
Due to experience, I found out that in order to get a beer to what I see as "moderate" carbonation (the average in commercial beers) I use a much higher amount of corn sugar then what I see in calculators on the web.
for example, I made a Tripel. when using a calculator like The Beer Recipator
it would show that the high end for this style would be 2.4 volumes, thus using 4.13oz (117g) of corn sugar per 5 gallon for priming. I used over double this amount - 8.83 oz. (250g) that should equal 4.15 volumes. However, the beer is carbonated to a level that I see as very similar to commercial examples of the style - maybe a little higher. I had the same experience with other batches of other styles.
Does anybody else experience this?
