It’s been a while since I’ve actually written anything,
partially due to work travel and partially due to just general laziness, but I’m
back. This beer is the third iteration of sour beer to come out of my sour
barrel. The barrel itself is surprisingly going strong and it’s up to six
generations of sour beer production. If you include the first two clean beers
you’re looking at 8 uses, which is pretty good for a $70 barrel that I got
almost 3 years ago. I really don’t do much to keep it going other than leaving
it empty for no more than a day. As long as it’s full there is less risk of
acetobacter and the barrel drying out and splitting. The one problem that I
have with it is that it sours beers very quickly. That’s not a bad thing per se
but it does require me to brew fairly often to keep it going. The beers that
come out of it have a nice house funk character that I can recognize from batch
to batch and a lactic acidity rather than a pedio acidity.
Appearance: The
beer pours a hazy orange-yellow with a small amount of white head that quickly
fades. I’m not surprised that the head retention is pour since the beer is not
truly carbonated and sour beers usually have pour head retention since the
Brett usually eats any protein structure given by any wheat I use.
Aroma: There is
surprisingly still a hint of barrel character that comes across as oak. Light
funk and some citrus notes. The acidity is apparent and there is a touch of vinegar
as well. I remember the volume of this beer being too low and I never topped it
up so I’m not shocked by the vinegar character.
Flavor: Sharp
acidity up front and a light acetic character on the finish with citrus notes
and funk in between. Oddly compared to the aroma the funk is much stronger in
the flavor.
Mouthfeel: Low
carbonation, dry finish with some sharp acidity. I’m hoping the carbonation
will pick up, but I’m worried with the increased carbonation that the acidity
will become even more apparent.
Overall: I think
the acidity is a little sharp, which is probably due to the beer being in the
barrel for too long. I try to pull them out a lot quicker than I have, but doing
so requires me to have time to brew and refill it. I’m disappointed in the
carbonation. I didn’t add any fresh yeast to increase the speed of the
carbonation. I’ve done this in the past and the beer eventually carbonates
usually, but it takes a while. Due to this I think I’m going to go back to
using Champagne yeast to carbonate my sours. I like that its carbonated quicker
and it also guarantees that the beer will carbonate because the yeast is fresh,
rather than relying on old yeast.
I'm curious to see how the acetic characters evolves over time. Have you tried adding more hops to inhibit lacto production and achieve a softer pull for next time around? I know a lot of the big sour producers add more hops than we do on the home brew scale, and I'm pretty sure it's because their house cultures would make acid beers without them.
ReplyDeleteI have not tried adding more hops, but that would only inhibit the lacto production. Acetic acid production would come from acetobacter, which is not inhibited by iso-alpha acids. That's more about limiting O2 intake post fermentation. I actually like the lactic character that I get from the barrel, but I might try to increase the hops next time to see if it slows down production of lactic acid. My current plan, if I want to reduce acidity, is to start blending with basic saisons and just stay on top of removing beer from the barrel.
