You definitely make some beautiful looking beer!! I have used gelatin and biofine in the past with good results but never have I had beer quite this crystal clear. Well done!
Thanks brother. I swear I'm trying over here. On every batch I want the beer to look this way. Taste is first, clearly but I always want the beer to look polished too. I just finished a run of seven batches with S-04 and that yeast drops like a rock so I think there will be some clear ales coming up. Some process "simplification" has helped on the clarity front as well, IMO. Cheers.
007 is my favorite ale yeast. Attenuates and drops out to a solid cake. I haven’t used 04 in a long time. 007 and 04 are hard to tell apart for me. Nice beer!
Yeah, a lot of the UK yeast strains drop nicely and leave a nice, clear beer behind. They can stall or leave the beer slightly underattenuated under the right (wrong?) conditions and many of them are notorious for diacetyl too. On the lager side, Czech 2278 and White Labs 940 are known for "medium-high" and "high" flocculation which is a big help.
For years I have been trying to determine what aspects of brewing can impact clarity. The crush, the mash process, pH numbers, yeast strain, boil rate, etc. With no real scientific backup for this, I have to assume that improper pH numbers throughout the process must have an impact on clarity. One of the "simplifications" came from Brewbama who displays his beautiful beers here often. His strategy (which I believe was inspired by Gordon Strong) was to just get your strike water to a premash pH of 5.5 and let the rest take care of itself. Some who like to focus heavily on mash pH might find this reckless but it seems to work beautifully. Another angle on it is to withhold very dark grains from the mash, crush them separately and add them to the MT at the end of the mash. This way they won't futz with mash pH very much. Very dark grains are usually in small percentages and each brewer can decide what to mash and what to add later as they see fit. If I make a darker beer with maybe 1-2% carafa or midnight wheat, I can easily hold that until the end. I have a Vienna Lager on tap now where I did this with carafa. It's delicious, well-balanced and clear. You could literally put your pH meter on the shelf with this approach and I pretty much have. I have a perfectly good Apera meter that I just have not used since I started this. Yes, I needed it to determine how much acid I needed to get my strike water and sparge water to a pH of 5.5 but after that... I don't bother taking readings anymore. The mash pH is going to be in range. For those who
prefer to get into the mud and look at numbers, plot and chart them, etc... avert your eyes.
