Hey Everyone,
So I've been struggling with bottling any of my beers that use wyeast 1968 (WLP002). Any beer that I put in a bottle will end up overcarbonated. I even keg and bottle off the keg. I know the source of the issue is that the yeast doesn't attenuate the sugars completely and then reattenuates in the bottle.
What I've tried:
Oxygen system: Helped quite a bit. I've found 1968 to love o2 (other sources have confirmed this) The pure o2 increased my attenuation by 1.004sg on back to back recipes.
Rousing(swirl method): no real help.
Rousing (sanitized spoon): So far the most promising. One recipe stopped at 1.020. When roused the 1st time dropped to 1.017. A second rousing dropped it to 1.014.
Things to rule out:
Fermentation Temp: I never let the fermentation temp drop after fermentation has started. Always finish +68F
Pitching Rate: Starters with new packs and 8-16oz harvested yeast pitches.
Some people have issues when bottling this yeast, some don't. Let's get to the bottom of it.
Thanks, Jeff
