wailingguitar said:Carbonated beer can still be filtered, so that isn't an issue. Krausening and spundig were especially popular techniques due to their efficiency. With krausening you have the advantage of not having to use an outside CO2 source, which saves money. With spundig, you have the added advantage of being able to turn beers over quicker. Both processes are very practical and economical on the large scale
Can carbed beer really be filtered without pulling the CO2 out? From what I've seen, the filter acts like one giant nucleation site and rips most of the CO2 out of solution. The off gassing also serves to decrease filtering effectiveness.
Then again, I don't know many home brewers that have the BMC budget.
