I'm trying to figure out what's going on with our past 3 batches of bottled beer.
Our first 3 batches were great. Perfect, even.
The only things we have changed were....
(1) Went from ale pale bucket for primary to 6.5 gallon glass carboy.
(2) Went from pitching subsequent batches on the primary's already existant yeast cake [of an unknown yeast type] to washing US-05 that was given to us by a local brewery and always pitching the correct amount of 50ml "yeast slurry".
(3) Went from gently swirling priming solution & beer in the bottling bucket to violently swirling until there is a 6 inch vortex for at least twice the stir time as the first three batches.
What's intersting about these three changes are...
(1) For some reason, switching to a glass carboy at primary led to less beer in the secondary. There was much more headspace in the secondary when the glass carboy was used as primary vessel. Unexplainable to me, but it did happen. This could potentially explain how the pre-rationed individual napkins, each full of 5 oz priming sugar, could be too much this go around when just 4 oz of sugar would have worked great.
(2) I personally believe that this US-05 is a "super yeast" since it has likely been used a number of generations by this brewer under 110% super-ideal conditions. But others say this has no effect whatsoever on over-carbonation
(3) Gently swirling worked great our first three batches. I told my friend to create a vortex when swirling with the last three batches. He made one crazy vortex for a longer period of time than I personally would have. Perhaps this could be the cause??
Other notes:
- First three batches took 4 weeks to carbonate. Last three batches took ~2 weeks to carbonate, and some bottles did explode. Only problem is that the beer is not really conditioned, because it still just tastes like "regular old beer" until the 4 week mark.
- There is only one bottle that I truly got to enjoy the taste of, and that was the half-full 22-oz bottle of Amarillo hops. Only 10 or 12 ounces of beer inside a 22-oz bottle, yet that beer was ALSO overcarbonated!! This leads me to believe that just 4 ounces of priming sugar for 4 gallons, or even just 2 ounces of priming sugar for the whole ~4 gallon batch, would have still led to overcarbonation.
Could it be possible that a violent stir / mixture of priming solution caused our bottled beer to overcarbonate??
... Or did the violent mixture just kick up a dormant fermentation that somehow wasn't able to complete with a 7 day primary / 21 day secondary (as well as a 10 day primary / 21 day secondary for the 6th and final batch, due to timing constraints)???
