i saw this debate on facebook yesterday..what would you do?
the guy buys a couple of corny kegs. he doesn't say where they're from. he receives them, and they appear to still have some soda in them. he brews a 10g batch, and accidentally racks half of the batch onto one of the new kegs before it was cleaned and sanitized. in other words, he racked it on top of what he thinks is old soda. would you dump it? or, ride it out and see what happens?
