All beer recipes that include using corn sugar for bottle conditioning advise that to bottle condition, you boil 1-2 cups of water, and add the corn sugar and stir until it dissolves. And then other texts that I’ve read advise simply that you can replace the corn sugar with DME if you want to improve the flavor of your beer.
What they don’t tell you, is that if you use DME instead of corn sugar, you shouldn’t just boil and dissolve, you should boil it for at least 15 minutes prior to adding the priming mixture to your beer and then bottling (make sure you don’t have a boilover — watch your pot).
I tried this while doing my most recent batch, and I have to say that I have much more excellent bottle conditioning results after only a few days.
I hope that this helps someone else out who was in the same predicament that I was.
Update: The new conditioning method worked great. Of note, You will need to use more DME for conditioning than corn sugar. I like my beer a little less fizzy than most recepies call for, so I use about .75-1.25 cup of DME per 5 gallon batch, depending on the style.
