I know it seems like there is a ring sticking out of my back and every time you pull the string I talk about clarity… so I apologize.
Over the weekend I used Biofine for the first time and at some point this week I will check the clarity on that beer. I have been a gel solution user for pretty much all my brewing since 1999. I often get clear beer. I sometimes get clearish beer and I have also gotten cloudy or cloudy-ish beer that stayed that way all throughout the keg. I get very clear wort into the fermenter, I do not use exotic malts that cause haze or a lot of low-floccing yeast. I pay attention to pH throughout the brewday and I always fine the beer. I have very high hopes that the Biofine will work well. I do hear some brewers say that their beer clears by itself without fining. I hate you. Just kidding, I don’t hate you but I hate you. :D I added the Biofine in a way where it would mix well with the beer being transferred to the keg which seems to be one of the big things about Biofine… good dispersion. If the biofine does not work to clear this beer (as gel sometimes doesn’t) then where should I look to find the issue? I do 60-minute, single infusion mashes around 150°. Nothing in my notes tells me that anything is “really different” between a beer that drops bright and one that stays stubbornly cloudy. I could point to my water but I am always using the same water so why would it vary? Thanks gang.
One thing I have noticed is that beer that sits an extra week in the fermenter at fermentation temperature (not cold crashed) often clears up pretty well on its own.
I wonder if sometimes we rush things and package too soon. In that case, yeast may resist flocculation simply because there is sugar or other nutrients still in suspension. But, in that case, if the beer has been chilled and taken off the yeast the time to finish out the fermentation completely, which the yeast really want to do, gets way slowed down. The yeast in suspension will finish it off eventually and then flocculate but only when they are ready.
When I got a Tilt hydrometer I noticed that fermentation is not always over when I think it is. A lot of fermentations go really fast for 3-5 days and then have a very slow tail (several more days) where they drop 2-3 more gravity points over that extended period. I think the rule of thumb of waiting 3 days after the last gravity change works well if you take this tail into account.
That’s a good angle. I typically let the beer sit in the fridge (ale or lager) for a good 6-7 days and then take it out and leave it on the basement floor for another week. Activity is done and the beer is sent to the keg on day 12, 13, 14… something like that. Are there cases when the beer is not done at that point? I’ll say no. Are there cases where things are still settling and the beer is not clear yet? Probably. But I always figured that’s what the finings are for and I don’t necessarily want to leave the beer in the fermenter much longer than 2 weeks. I do think my issue is more chill haze than anything but I just don’t see a pattern. I might use the same grains from the same bags and the same colony of yeast and one beer is crystal clear and one is clearish but certainly hazier. My water is very, very consistent so it’s not like a spike in TDS or bicarb or something so I don’t see water being the issue. My pH is always in the same zip code without BIG variations (I use an Omega meter) and in the old days I used pH test strips and had clear beer most of the time. Thanks tommymorris.
Mash pH? Are you getting a good cold and hot break? Those are the keys to beer clarity for me. BioFine works well too, but only if those things are ironed out.
Mash pH of between 5.3 and 5.4 (at room temp) with my Omega meter which has been excellent. Cold break when I chill (especially now with cold ground water temps) and then I rest the kettle in the sink with ice and water while everything settles. It’s usually 100% crystal clear wort going into the fermenter but occasionally I have had a bit of trub in the last half-gallon or so. As far as hot break, when the boil is over and I go to chill, I do see the “egg drop soup” pieces floating in the wort so I think that’s in place as well. But you do bring up something that could be the culprit: Lower boil rate. The LOers have mentioned something about reducing boil rate (I can’t remember the exact reason) and it’s possible that I have had some boils that were more sluggish in the past 6-12 months. I also remember being a new brewer and hearing that a good, strong boil is one good way to ensure clarity (NO WIMPY BOILS!) but a lot of things I heard when I was a new brewer turned out to be questionable so take it for what it’s worth. But it could absolutely be part of the issue. Thanks for the jolt on that one.
I have always just boiled where it it was just turning over. Mostly because i am always trying to squeeze too much into an undersized kettle. Boiling temp is boiling temp. Aggressive boils don’t get hotter than gentle boils.
But do you remember some of the old-school homebrewing commandments that said that a vigorous boil helped to ensure clear beer? Or am I remembering that wrong? Some of my boils are stronger than others which could explain why some beers are clearer than others. I also wonder if a weak boil does something where even finings don’t help (that’s been my issue with some beers even when adding gel solution TWICE!). I might be grabbing at straws but a weak boil seems to check a lot of boxes.
There was a Brulosophy Exbeeriment on this and the conclusion was that a weak boil and stronger boil created beers with very similar clarity. So there’s that. But I found a BYO article that does address the hot break and the relationship to clarity:
Last Saturday I made a Helles and had a pretty vigorous boil. The hot break was VERY noticeable in this batch. That is not always the case with my batches so when that beer is kegged and Biofine is used on it, I will be paying close attention to clarity. I know there is evidence that I’m sniffing around the wrong fire hydrant but it feels like there is something there.
So what if I came to the end of the boil and I did not see that noticeable hot break? Would that guarantee me a cloudy beer or maybe just make it more likely? I’m not married to this being the culprit but it seems to check a lot of boxes.
Yes I think a hot break is important to beer clarity. Different malts have differing proteins and some have more break material that others. I get a huge hot break with pils but much less than … say, Maris Otter. That said my maris otter beers come as clear as I want them too
Yeah, this helles was 80% Best Malz pils. Lots of hot break in this one. I’m going to just put this info in my back pocket and keep it in mind. Might be something there, might not.
Most commercial breweries either filter or centrifuge … the latter being probably the most common now due to less loss. BioFine works really well if all the other stuff falls in line
I’m keeping my fingers crossed on the Biofine. But it sounds like the clarifiers we use are not magic… other things need to fall in line first as you say and I think I have failed in that regard. If I hit a batch with a gel solution twice and it still doesn’t clear then it’s obvious I have done something. The boil rate is probably a spot where I’m not as tuned in… if it’s “at a boil”, fine. I do remember coming out to the garage this past Saturday and the kettle was really cruising. If I make 10 batches in a row with a more vigorous boil and I get more consistently clear beer then there is something to it. If not, the search continues. Thanks & cheers.
Their beer is ultra clear so maybe soft water + long boils + “everything else being perfect” is enough. I see a lot of crystal clear commercial beer and I don’t lose much sleep over that because I assume they have some sorcery to get the beer looking like that. Sometimes my beer looks like that and other times it does not. But I see other homebrewers getting very clear beer so I wonder what the variables are. Cheers.
All I can tell ya is that I don’t do anything other than Whirlfloc and cold crashing and I get the same results you do. Sometimes crystal, sometimes not. So maybe it’s not any of that stuff.
I think you will see that after a week or maybe more, your beer is going to be nice and clear. I just started using biofine too, 4-5 brews now and I haven’t had one that did not clear to absolute crystal clarity. With that said, the batches were 4 lagers using OYL106 and one pale using Denny’s 1450.
The first batch I used 5ml to a 5 gallon keg and that took maybe 12-14 days to fully clear. I was impatient and tapped the keg in a week and it was not clear enough. All other batches have cleared quickly after I upped the solution to 10 ml, about a week. Again, impatient and had to verify that 10 works for my beers. I might go to 15ml just to compare.
