New Mangrove Jack's strains?

[lasultana]

On a different forum (ba or aussiehomebrewer, not sure) they said that M42 (M07) is in fact the same yeast as Danstar Nottingham.
Does anybody have further information on this?
Thanks!

Kegged the Amarillo SMaSH IPA today. Final Gravity was 1.013 for a 79% attenuation (1 packet). Very pleased with the outcome. Initial taste was very good. Will let it sit on gas for about a week and pour my first pint afterwards. So far I'd definitely use this yeast again. [emoji106]🏻

No it doesn't attenuate as much as notti. Its more comparable to S-04 but much better in my opinion. For a liquid yeast comparison it is like wlp007.

Brewed up 4 beers yesterday.
let them cool over night and will pitch some MGJ yeasts today.
One is a Rye IPA with M42 but the other one is a Cali Common with M54.
I got a bit more beer than expected for the Cali Common so there's not much head space left in my 18L bucket (about 3 litres)
Anyone know if this yeast usually has a big Krausen?
OG is 1.052 so if it's something like US-05 or the M42 it shouldn't be a problem.
I also read it is a slow starter so that also helps.

Thanks

If I'm allowed to quote myself

All 4 beers were bubbling away when I got up this morning. So I don't get this general consensus that mj yeasts are significantly slow starters. The m42 is going crazy and the m54 is a bit more reserved. Will report back in a few weeks. I never brewed a Cali common but have brewed the same rye IPA with US-05 a while back. So I'll see if I can can compare them by memory

Hey thanks for the answer.
Do you have any hard facts on that or is it just hearsay? I've read that other people assume it's a dry WLP 007 - and others that say it's Nottingham...
How far does it attenuate for you? According to its data sheet it should attenuate 77-82 % (which would be the Nottingham range). The temperature range doesn't exactly fit Nottingham, it starts too high.
So again: Any facts?
Thanks!

007 is quite fruity, sort of plum-like, just like 002. M42 is not supposed to give these esters.

 

[thehaze]

I read that the Wheat yeast and the Witbier yeast from Mangrove Jacks' are quite OK and reasonable for the style.

Can anybody confirm?

I am also looking for a good belgian strain. I can see they have a few. Are any of those good for saisons and Belgian Dark Strong Ales?

I just brewed a Witbier with Mangrove Jack's Witbier yeast. I think it was reasonable. It gave good amount of Witbier characteristics, but also quite strong flavours. I was hoping a bit more delicate ester production for this style. But my fermentation temperature might have been bit too high, and the flavours could mellow with time. Would use diffrent strain next time though.

I like M47 for dubbels and blondes, although you have to push the fermentation temperature a bit to really get the yeast character. It's not the most attenuative strain as Belgians go, so it may not be ideal in a stronger ale.
The M29 is nice for saisons, and very attenuative, but again, I find that it needs higher temperatures to give the right character.

 

[Weezy]

my experience with the Cali Common with M54, it started fine but didn't finish very well and ended up kind of sweet so some rousing might be needed or late sugar

Note my experience at all, but I do use a temp controlled ferm chamber. Are you controlling temperatures?

I have never used wlp007 so I must admit that is just information I found elsewhere on the internet.

For Notti v M42 I also unfortunately I don't have any hard facts only some things I have observed the 5 or so times I have brewed with each.

All different beers with different OGs and mash temps so never a direct comparison. However they were all brewed in my basement around 64F ambient temperature. Looking at my notes a few of the beers with Notti ended under 1.010 but all the M42 beers ended between 1.010 and 1.013.
M42 seems to be more forgiving of higher temperatures too but Notti seems to work faster and drop quicker. So I would say they have some similarities but are significantly different.
I guess the only way to really compare them is to do a split batch with a moderately hopped medium to light coloured beer.

I found this when looking for a comparison:

Again just a fellow brewer's opinion but useful for anyone interested in finding out more about how MJ yeasts (probably) compare to other strains.
Some interesting links to other yeast comparison charts too.

I am holding an unopened packet MJ31 bought at texas farmboy shop in Houston..shall I brew with it?

Go for it. Unfortunately the beer I brewed with M31 didn't turn out as well as I'd hoped, but that's more my recipe than the yeast. I used whole homegrown hops in a fine mesh bag that just didn't give me the bitterness I'd hoped for. The yeast character was pretty spot-on though.

If you're looking for a dry yeast for Belgian darks then Fermentis T-58 would be an obvious choice, not the most "shouty" but it's supposedly used by De Struisse who make benchmark beers in that style. Not sure it would work with saisons though. You should also hold a little bit back and add it as a 5-10% seasoning to NEIPA yeast blends, per the ongoing Tree House thread....

A previous thread had some MJ equivalencies, allegedly. I've used M36 quite a bit - it seems fine, I'm waiting to do some big yeast comparison experiments though.

 

[JKaranka]

Have been using M42 and M44 for a while now. Just brewed a Belgian with the M31 Tripel yeast (all Pilsner, 15% sugar). I guess with the attenuation it has that OG of 1.061 might deliver a 7.5% abv beer...

PS: assertively hopped with Bramling Cross, which I do not often see in these styles

 

[Shenanigans]

Brewed a Rye IPA with M42 which turned out good but still a bit catty from the Simcoe. Might be because I dry hopped for 2 Weeks. Maybe it just needs a few Weeks to calm down a bit. I brewed almost the same beer with US-05 and it was significantly smoother.

 

[Shenanigans]

Has anyone actually brewed a Barley wine with M42?
I was thinking about doing a beer like SN Bigfoot but replacing the Chico with M42 because I want to try not order any new brew stuff until I've used up what I already have.

 

[Shenanigans]

This thread has died a little

Just wanted to report I will brewing a few beers with MJ yeasts soon and will give some feedback here in the Spring.
First two will be a Brown porter with M36 and an IPA with M42 in a few weeks.
Although I can already say that M42 makes a good IPA.

In March/April I want to use up a pack of M54 but don't feel like making a cali common so it will be a Sticke (secret/strong) Altbier.
Not quite imperial but about 6.5% instead of the normal approx. 5%.

OG 1.060 IBU 42

 

[GurraG]

I'd be happy to hear how the Sticke comes out!

Hopefully it's ready sometime in May.

Have you used M54? States on there site not to re-use.

I only used it for a Cali Commom.
Turned out OK but I never had a commercial example so I couldn't compare.

For the Sticke I ill use a new pack but I wouldn't take much notice of them recommending not to reuse it.
Might be some minor flavour/characteristic changes but of course they would rather that we always buy a new pack.

Thanks, what was the floccuation like?

 

[user 227424]

Looking forward to finding out...

I love mangrove jack yeast

Just about all I’m using anymore

Have you used M54? What styles have you use mangrove for? I'm looking for a high floccation yeast that can make beer it under 2 weeks using pressure fermentation. Hopefully, german lagers.

 

[jalc6927]

I’ve used 54 numerous times with great results right from the pouch without rehydration

I used a lager one as well with great results as well, don’t have the specific number with me

I’d like to try a witbier strain next time I do my blue moon style

 

[Shenanigans]

Flocculation was very good. One of the clearest beers I every brewed. Attenuation was higher than I expected too but that could be process related.

 

[Shenanigans]

About 6 hours ago I pitched 3 MJ yeasts.
M36 for a Brown porter
M42 for an IPA
M21 for a White IPA

The 42 is already bubbling about every 2 mins - only know because I'm surfing and sitting beside the fermenters

Sounds awesome. I had to get my LHBS to order some M54, he's great like that. Can't wait!
