New Mangrove Jack's strains?

[modifier]

Does anybody have more experiences with the M36?

I made an oaty english ipa with it and was quite pleased. Apparent attenuation was 74% i think, it kinda really fused the flavours together. Nice, soft bitterness, aftertaste was mostly malty, esters were subtle, but still enough for brittish style.
Even my mother liked it and she doesn't even drink beer..

EDIT: Well, the yeast i used was previously called Burton Union, but Liberty bell is the new name for it so.. It's the same yeast, maybe just hearthier.
Also i want to warn you about the flocculation! It doesn't pack as tight as most brittish strains, so use irish moss, cold crash a bit if you can and be careful when racking and it'll be clear.

I've tried the majority of them.
Living in New Zealand I have ready access to the brand.

Here's my thoughts:
[...]

am i missing any?

Have you tried the m41 belgian ale?

 

[crusader1612]

Have you tried the m41 belgian ale?

Yep - Not good!
after trying beers with this, and the new M29, I believe the 41 is actually the old M27 (I do not like this) and the M29 is actually a new Saison type strain.
I could be wrong, but it tastes very similar, and I'm not a fan TBH.

Crazy thing happened to me on my first ferment with the M10-Workhorse. Did a 10 gal cream ale and split between that and Wyeast 2112. I do 3 week primary and then keg. So at the end of 3 weeks the 2112 was at the FG 1.012 that it was supposed to hit and the M10 was at 1.016. Kegged both and on 30 psi at 68* for 3 days,then 20 for 1 week and in the kegerator it went. Nothing but foam from the M10 , 2112 pouring well. Keep popping the relief valve for 1 week twice a day. When it started pouring so I got more then 1/2 glass I put the hydrometer to it and it was 1.009 WTF?

Workhorse will ferment at lowtemps.
hence why it continued to drop.

 

[hottpeper13]

You would think that after 3 weeks at 70* it would be done. The taste is much more fruity than the 2112 which is kinda bland. Might have to try this beside 2565 at 55* and see what it tastes like.

thanks man!

Well my first M36 liberty based beer has turned out very nice and balanced between the malt and hops.

Basically tried this instead of going with 34/70 but I haven't used the 34/70 for this grain bill so cannot compare.

Grain bill was 4.2Kg (94% pilsner, 3% light crystal, 3% dextrin).
Water profile was fairly balanced (100 Ca, 50 Cl, 75 SO4)
10g 18% AA for the boil, 70g staggered hop additions with 30g dry hop.

The fruity esters are not there like the starter batch had which was a little disappointing. I fermented at 19c for the first 2-3 days before ramping up compared to the starter being done at 21c so I guess that's why.

1050 to 1014 (7 days) which is fairly spot on to what I was after (the dextrin ups the FG) as I like my beer 4.5~5.0 abv. Flocculated very well and dropped clear with 24hr 4c cold crash, kegged day 9 and sampled day 14.

I did split my starter so will make another similar beer perhaps fermenting 20c to start with. Over the weekend I met the master brewer from Sprig and Fern (Nelson, NZ) and got the inside word on the hops they use for the beer I was copying!

I was literally just logging on to write a review of M47-- I brewed four different beers with it in the last couple of months and had been planning to write up my findings, as there weren't any good reviews out yet when I purchased it. Should have the post up soon!

 

[cycomiko]

I have a Belgian Blonde just finishing up with M47 currently. Hoping it turns out as nice as people are saying.

I'm very interested to hear your thoughts on this!

 

[eulipion2]

Finally brewed my wit with M21 yesterday. Bubbling along happily. Next brew will be a Belgian single with the Tripel strain, and an ordinary bitter with Liberty Bell. Slowly working my way through the lineup!

 

[TheMadKing]

Just started a porter with M03 Dark Ale/M15 Empire ale (same thing I believe), fermentation was vigorous after only 4 hours, so I'm pretty happy with it so far, I'll report back on the finished product!

 

[Kharnynb]

haven't used their beer yeasts yet, but the cider yeast makes a decent dry cider, not too dried out, but nice and tart.

 

[isildur]

Hi guys!
Have anyone here used M15 Empire Ale with high gravity stuff like Imperial Stout or Barleywine ? What is alcohol tolerance of that strain ?

 

[modifier]

Their documents say it's 8%, so M15 isn't for imperial strength brews..

 

[blaster_54738]

I just used M15 on an oatmeal stout. OG was 1.060 and fermenting at 68. It took off right away, bubbled well for about 2 days and has slowed now. I haven't taken a read lately though. Did try a sample yesterday and it was very good so I can report back when it's done fermenting. I've used their yeast a few times and have had pretty good results with it

 

[Radboud]

I started a kit and kilo yorkshire bitter last weekend with Liberty Bell (had to choose from that or Nottingham), I will post the results.

 

[Shenanigans]

My Goose Island IPA using M42 is now 16 days in the bottle and tastes very good. I dry hopped with Cascade and the grapefruit/citrus flavour is really shining through. I don't know if it's the yeast or a combination of other factors. For example I ended up dry hopping for 14 days instead of 7. I only have 5 bottles from 30 left so I'll definitely brew it again but only a 7 day dry hop and see if I get similar results. Anyway I wouldn't hesitate using it in an IPA again, would prefer it to S-04.

Reporting back:

OG: 1.052
FG 1.020

This is WAAAY underattenuated

My mash temp was 150 for 60 minutes, and the bulk of my grain was standard 2-row. I rehydrated the yeast, fermented at 66, ramped to 72 after 6 days. FG has been stable for 3 days, so I'm starting the cold crash and planning to keg it on friday.

Taste-wise, it's clean but there's a hint of lingering bitterness that's not hop related. It has a heavy mouthfeel but doesn't taste overly sweet.

Overall, I would use S04 if I had to do it over again.

i have mixed feelings about MJ yeasts. i had batches that tasted great, some bad. some attenuated well some not. some cleared some stayed cloudy.
latest batch of APA with m42. 4 weeks in primary - the most murky beer i’ve ever seen.

The one beer I brewed with M42 the yeast dropped like a stone and makes a compact layer on the bottom of the bottle. I ordered 3 more packs but still have to decide what I want to brew with them. I have 2 packs of the wit yeast too. 1 for a Raging Bitch inspired Belgian IPA and the other for a white IPA.

I also have a pack of liberty belle , anyone have a recipe they would recommend for that?

i think MJ might be having quality control issues or something. how is it that peoples experience with them is so varied. i even had mixed results with the same yeast.
a while back made hefe with m20, beer was spot on flavour and appearance-wise. made the same batch again, same ingredients, same equipment same yeast - the beer was very different. flavour was weird and the yeast flocculated and compacted like mad - making it a kristallweizen.
im bottling a belgian this weekend with M47 yeast, will see how that goes.
cheers.

 

[Shenanigans]

I still need to try but I think maybe M42 it's not the yeast for a bone dry IPA/DIPA but more for something that should have a decent bit of malt character. So basically any IPA where they/or I decided to use British pale ale as the base malt i.e. Maris Otter, Golden Promise etc.
Keeping that in mind I'm going to try it out for a Rogue Brutal Bitter/IPA inspired beer.
Using it instead of Pacman and swapping the Crystal hops with Mt. Hood and Strisselspalt.

I would not jump to conclusions because different people with different setups brewing different recipes are getting different results.

 

[brewbama]

I was super excited with MJ offerings but after using them a few times I had some interesting unanticipated tastes from MJ on a couple different strains. Not bad per se, just unanticipated which does not lend itself to the predictability I am trying to get out of a dry yeast.

 

[Mihkelj]

Has anyone brewed a bigger beer using only one sachet of their yeast? Mangrove Jacks say to use 2 packs per 23 litres/ 6 gal for ales with an OG over 1.050. I just bottled one with on OG of 1.061 with two packs of M42 and there was a massive layer of yeast on the bottom of the fermentor. I'm just wondering if it would be possible to get away with one pack as long as the gravity isn't too high. Could it just be their way of selling more yeast?

Also, they state you shouldn't harvest it, quote: "As a result of the drying process, Mangrove Jack’s Craft Series dried yeasts are not suitable for harvesting and/or repitching." People harvest other dried yeasts, so what makes theirs different?

I tried a single pack. And it didn't turn out well. Undeepitching is very easy with these yeasts as the packs are 1.5g smaller than fermentis as well. I always overpotch these yeasts now, as some take longer to take off and a small overpotch is not really detrimental IMO

The reason for no repitching is because these strains (particularly M44) is that it morphs significantly from beee to beer and dries out further.

 

[Radboud]

This one is still fermenting, took off fast enough and has been bubbling away steadily. Is this strain known to be slow? OG was 1.046, pitched 1 pack into well aerated 5G.

 

[eulipion2]

Just bottled my witbier (M21) yesterday. OG 1.045, FG 1.012. Despite being flat, it tasted really nice. Next up is a Belgian single using the Tripel yeast (M31), and a smoked porter using US West Coast (M44).
