Mangrove Jack Craft Series Yeasts

[Milhouse]

Judging off my own experience and what I have read elsewhere it is a blend of two yeasts, one fast acting and another much slower.

Even so it doesn't attenuate that well and does need time to condition, tastes a bit yeasty and masks malt flavour early on.

I measured the SG and its come down 22 points from 1042 in 2 days, so in your experience would you expect this to drop further even though I can't see any bubbling at all in the airlock?

 

[Milhouse]

Probably will drop a little more, I would expect about 60% AA. A little extra time in the fermenter certainly won't hurt.

I'm hoping it drops to at least 1012 so I'll test it again after its been fermenting a week, normally on my previous dozen brews or so fermentation has finished by then and I leave it a further week. Just not seen airlock activity apparently finish in less than 48 hours.

Never judge anything by airlock activity. Only ever trust your hydrometer readings. You're not watching it all of the time, it may still be fermenting slowly, and you're just not seeing the bubbling when it happens

Where did you read that?

 

[Milhouse]

Don't go too much on airlock activity go on change in sg. That said I leave my brews around 2 weeks before testing and they are always done by then. Rea

I don't remember, it was an overseas forum, I have had a quick Google and can't find it now. I should say it was someone's opinion based on their observations. Which I tend to agree with as it ferments really well hard for a few days then takes ages to finish up

I thought I'd post my findings on the M36 - Liberty Bell yeast.

It's pretty great hey, I've been using it for the last coupe brews and really impressed with it, will definitely use it again!

Maybe it was this forum, as it has some good observations on Mangrove Jack yeasts and includes the M15 ?
