The fact you made a small cake implies cell division was being inhibited, which would stress the yeast and in turn make it throw more off-flavours. I'd look at better aeration and maybe some yeast nutrient - and 68F is a touch on the warm side for British yeasts, maybe let it free rise from 64F?
Have a good read of this big thread : https://www.homebrewtalk.com/forum/...emps-and-profiles-cybi-other-thoughts.221817/
I bought this yeast yesterday at the LHBS on a whim when my recipe calls for WY 1968...Thought I'd give it a try and maybe save a few bucks in the process. Glad I checked here, but wish I had done so BEFORE shopping!
Oh well. I am brewing "I'm not bitter, I'm thirsty" (Best Bitter) from BCS.
I'm going to mash low and hope for the best!
Is Lallemand/Danstar London ESB yeast less estery than Windsor? The Lallemand technical data sheets flavor profile diagrams show it to indeed be less estery than Windsor. I find Windsor to be generally rather dull. Does this make London ESB even more dull?
I brewed this on the 27th and pitched yeast at 4:25 at 68*. By about 11pm I saw some foam appearing.
By morning it was going strong. It raged on through the afternoon and by bedtime yesterday the high kreusen had fallen and it was back to a small surface foam. The yeast goes to work!
Is it even possible for this one packet of yeast to chew through 3.5 gallons of 1.048 wort in 24 hours? I haven't measured yet, but doesn't seem likely.
I've been bumping the temp and it sits at about 73* hoping to keep it from sleeping entirely.
I've bottled the beer and can report that the flavor is good and I don't really detect much residual sweetness, if any.
The yeast doesn't floc well as others have stated, but if a bottle sits in your fridge a couple days, it should pour mostly clear.
The problem I am having is that the carbonation just didn't come through after 2+ weeks of waiting.
I just double-checked the priming sugar I used and it is adequate (1.5 oz corn sugar for 3.25 gallons).
I have the bottles sitting at ~70F currently where they were downstairs in the low 60's.
Maybe that will help, but currently the beer is pretty flat.
Maybe the yeast?
Great questions, which unfortunately I cannot yet answer. I just bought some London ESB and will form opinions on that later. In the meantime, you might want to try Munton's ale yeast, which is very similar, very low attenuator like the others, but has a huge fruity ester thing going on like tutti fruitti.
Would that make Munton's ideal for juicy-fruity IPA's? There are two Munton yeasts. Which one are you referencing here. Standard or Gold?
Munton's ordinary is a close relative of S-33 and Windsor and seems to be widely white-labelled in kits.
Munton's Gold hasn't been sequenced but may well be a Nottingham derivative.
1.5 oz sugar for 3.25 gallons is definitely not adequate to produce pleasent carbonation, at least for my taste. I use around 5.5 oz table sugar ( beet or cane ) for 6 gallons. That's around 2.55 vol CO2. Works well for many styles of beer. I used 6.9 oz table sugar for 6.35 gallons of Hefeweizens, giving me a 2.85 vol CO2, which was OK. My latest Biere de Garde used 6.5 oz table sugar for 6.5 gallons of beer giving me around 2.75 vol CO2. I was shooting for 2.9, but I ended up with 0.5 gallons more beer. I tasted it. It needed more and I will go higher next time.
Your 1.5 corn sugar, which you need to use more than table sugar for the same purpose, will have given you around 1.7 vol CO2, which is why you didn't experience any " noticeable " carbonation levels. It's not an yeast problem, especially for one that does not flocculate well. I think the amount of corn sugar used was way too little.
I think it's potentially both. I got the 1.5 oz from Brewers Friend priming calculator, hitting somewhere in the middle of British Style Ales. Maybe a bit on the low side in comparison to other styles but shouldn't be flat.
However, after adding only the yeast to the beer in the keg, the yeast pressurized the beer in the keg. To me this indicates the the 34/70 ate the sugar that the ESB yeast failed to.
Just to add my experience:
I brewed a session IPA (1.046 OG) with this yeast 4 days ago. It took off like a rocket after I added the rehydrated yeast: within 10 hours a small krausen and airlock activity. The next day it was going bananas. After 24 hours or so it settled down, and today I checked and the gravity is at 1.011. The sample tasted great. So I might bottle this on the weekend, just a week after brewing.
If you add a yeast with higher attenuation after one with lower attenuation, than the second yeast will eat what the first left over. This does not necessarily have to be the priming sugar. Especially english strains can leave big amounts of sugar behind which are unfermentable for them, but perfectly fine for other strains.
It's a typical English strain. You have to mash accordingly and probably also want to include some fully fermentable sugar like Lyle's golden syrup in the recipe.This strain is well documented to be unable to ferment maltotriose - whereas those higher attenuating yeasts can do it.
In my experience with this yeast - it doesn’t leave the beer sweet - but only with a more full mouthfeel. It can though leave an alarmingly high FG.

I just read through this whole thread because I picked up a pack of this on a whim at the LHBS. I am planning to brew a dark mild tomorrow with an OG of (hopefully) around 1.038.
Since this is fairly low OG, do I need to adjust my mash temps for the ESB yeast? I’m planning on mashing at 158, btw.
Well if you mash that warm your ABV will only be like 2%. Whatever floats your boat. I would suggest adding more malt or brew a smaller batch to raise OG and thus ABV. Mash temp is less a worry than the OG methinks.
I’m in no position to really question anyone as I am barely above a beginner status. But, I am copying the recipe called Reaper’s Mild here on HBT and he said mash at 158. The point of a mild is to be, well, mild.
I only asked this question specific to this yeast because I don’t want my beer to go from 1.038 to like 1.025. Obviously that’s an exaggeration but people have had some issues but it seems as most have been with higher OGs. Oh well, it will be beer either way. Cheers
