Mangrove Jacks Belgians: M31 and M41. Any views?

Post by MTW » Wed Oct 10, 2018 9:15 am

Haven't been here for a while, after a few months off. Anyway, got my backside in gear and planning to ferment 5kg pale, 500g special b and a bit of sugar for a darkish 20L of Belgian somethingorother. I've got 2 packets each of M31 and M41. Never used before.

Anyone got any experiences?
Cheers

Not those specific two but I brewed a Belgian Dubbel a couple of years ago using MJ 27 and it turned out very well. I'm guessing that MJ 41 is what used to be called MJ 27 as the latter is no longer mentioned on their site and the description of 41 fits with 27.
Best wishes

Thanks Dave. Glad yours turned out well. From a quick Google, it looks like M27 is (or was) a saison yeast, despite just being called 'Belgian Ale'. I can see why they've ended the confusion in the line up. Where M27 has gone, I don't know. M41 is described on the packet as monastic, and M31 as being suited to tripels or 'a range of Belgian Styles'. I have had a decent 'tripel' made with a saison yeast (Belle), but I don't want this one shooting down to 1.002 or anything. I hope that M31 is not M27 repackaged (though I appreciate you got good results in any case).

Edit - I see M47 is on their current list as as 'Belgian Abbey'. Hopefully this means they've got at least two different original abbey sources there, with the 'monastic' M41 as well.

I'm amazed how little is out there on people's results from these...

I did a Westvleteren 12 clone (all grain) with M31 and it's the best beer I've made to date, got it from 1.092 down to 1.011 which left plenty of body and flavour.

I used M47 place of the standard unbranded yeast in an old bulldog lager kit I got give, boosted with a little bit of candi sugar and a hop tea. Got that from 1.048 down to 1.016 but it still tasted a little thin. Perfectly drinkable though with some nice belgiany flavours.

No experience of M41 but if the other 2 were anything to go on, it'll be great.

Hope that helps

I'm not sure if it's the same strain but I did use the saison yeast a while back (before the rebrand.) Found it quite balanced and not too much of any of the big flavours (banana/bubblegum/phenolic) but definitely identifiable as a saison rather than a Belgian blonde etc.

Thanks all. Brewed today and pitched 2 rehydrated packs of M31 into a 1.068 Belgian. I got some feedback from a friend yesterday who said he used M31 in his kwak clone. I tasted that at the time and it was terrific, so fingers crossed.

For what it's worth, M41 certainly doesn't read like a saison strain on the pack, so I don't think M27 can have become M41, but I can't be sure.

I'm pretty sure M27 became M29 French Saison. Yeast sans frontieres.

Any recommendations for a tried and tested (simple) all grain recipe for a Belgian ale with M31 would be great, I know there are huge breadths in that genre but an introductory "can't fail" would be great to add to the shortlist of beers to brew very soon.

Here's the recipe I used for a quad/westy clone, warts and all.

Notes:
• I made my own candi sugar but the recipe is significantly easier, if not more expensive, to buy it.
• I used some oldish Tetnaang hops as the late addition as I didn't have any other noble hops to hand.
• Be very careful if using solid candi sugar as it has a tendency to sink to the bottom of the boiler and stick
• Whilst the recipe is fairly simple, temp control is key to getting the best results.
• The finished product needs a fairly long time to age and mellow out
• I used a grainfather so you may need to adjust according to your system efficiency

It's off well this morning. Can only have been a maximum of 12 hours or so lag. Lots of CO2, a fairly creamy head, and some banana smell just starting to come through:
