These appear to be:

M15 Empire ale
M36 Liberty Bell
M42 New World Strong ale
M44 US West Coast Ale

Any views on any of these? And how they compare with the alternative from other yeast manufacturers, US-05, S-04, S-33, Nottingham, Windsor, ESB, Muntons Gold, Gervin etc?

Would you strongly recommend any of them?

I’ve only used the Empire and it wasn’t suitable for the type of beer I was brewing. It throws out loads of dark fruit. You would need to use it in a dark beer where this fruit cake flavour will be balanced by the malts used.

I would be interested to know what people think about the liberty bell though.
I don’t have hobbies. I’m developing a robust post-apocalyptic skill set.

I've not used any of the above bar the M15 Empire , and my thoughts are well known on the subject, strong fruity ester profile with high attenuation in my experience.  Other MJ Yeasts I have used tho :

M02 Cider - Clean, fast fermenter, gave a nice clean apple flavour and attenuates well but not quite to full dryness, 1.002-1.006 most common IMO - this leaves a small amount of residual sweetness to the brew

M31 Belgian Triple - Clean belgian charecter, 70:30 balance in favour of phenolic spice in my experience, suits the Belgian brown Ale I used it for (but would not be so good in a blonde as I prefer esters) fermented @ 22 degrees - profile may shift if pushed at a higher temp tho. 72% Attenuation in a 7% abv brew.  Floculates well with time, but its not a stone dropper.

Beer is like porn - you can buy it easily enough, but its so much more fun to make it [wink]

I've used all but M15. Here's my thoughts:

M36 - only used it once. Made a nice golden ale and produced some nice esters. Wasn't sure about the beer to start with (due to the Jester hops), but it was another that came good a couple of months in. Would use it again for sure.

M42 - again, only used it once in a hoppy Motueka pale ale. Ferments clean and beer is perfectly clear. Beer is not as hoppy as I'd expect for using 100g, not sure if it was a duff pack of hops or the yeast stripped the flavour. Not fussed about using it again.

M44 - used this a fair bit. Without making the same beer and trying it side by side, I honestly could not tell you if there's any difference against US-05. M44 is more expensive and you get less (10g vs 11.5g), which could make a difference in a high OG brew. Often, but not always, takes FOREVER to get going. I've had beers take 72hrs to start, even with rehydrating. I've used it in my current Mosaic IPA and have found it really hard to pour a clear pint without disturbing the yeast, but not had this issue before that I recall. Verdict, just use US-05.

I've used the M15 Empire Ale in its former name M03 Newcastle Dark Ale.  I used it in a brown ale and was happy with the end result, but wasn't thrilled with the performance of it.  It took ages to get going and also took ages to finish... even then, it finished a good few points higher thn I was expecting.  The M44 was great, although I couldn't notice any difference between it and US-05, in terms of performance and finished product.... BRY-97 performed better and I think it flocced better too.  M42 New World Strong Ale performed terribly for me and I had to overpitch a packet of Gervin GV12 to get the ferment to finish.  I wouldn't use it again.  Not used the Liberty Bell.

Other reports I've read about M42 have been very different, that it performs brilliantly and ferments out in about four days. It's pretty normal for people to have vastly different experiences of the same yeast, it seems.

Also used M36 to good effect in a Golden Ale quite fruity for a dried yeast worth a go if you want something with a bit more character than your standard options

Yeah, I'd heard good reports too, thats why I gave it a go.  I can only speak as I find though.  Others have not had favourable reports on the Lallemand London ESB dried yeast, but I have been very happy with my two attempts using it.

Only one possible conclusion. It's you!  [wink]
