carbonation
Hi,
I have a few questions about carbonated beverages, I'd be grateful for any answers you can provide or pointers to places I can find answers... In making carbonated beverages through fermentation is there a formula to describe the C02 pressure that will be generated by fermenting a known amount of carbohydrates in a bottle of a given volume containing a within it a specified volume of beverage (i.e. beer, cider, Champaign)? I'm wondering how the air space in a bottle affects the carbonation. If the bottle has too much empty space will the beverage be flat. If there is not enough empty space might the bottle burst? What is the typical the amount of sugar added at bottling to generate beer, cider, champaign? What is the usual pressure in a bottle of beer, soda, champaign? Thanks, |

Yes, the head space does factor in but there are so many other variables. Your unknown variables are the effectiveness of the yeast and the fermentables. There is no usual pressure for beer, soda, Champaign. The volumes dissolved are quite variable. For example, a recipe may call for 3/4 cup of corn sugar per 5 gallon batch for bottling. This takes into account the desired level of carbonation, the yeast, and the fermentability of the corn sugar. Those who brew know their fermentability and yeast attenuation only approximately. If you need precise carbonation, forced carbonation would be the way to go. Cheers, Tom |

But a generic amount of carbonation in beer is 1 atmosphere, and in champagne 2-3 atmospheres. I have no idea for soda... One cup of corn sugar per 5 gallons gets close to the one atmosphere figure, and for champagnes simple double or triple that amount. Cheers, Ken |
