Anyone ever make a warm fermenting mead with this one?

I'm thinking about an unpasteurized (cold) mix (water+honey+mix like hell with a wine degasser).

I'm then thinking about letting it ferment at around 78 - 80 degrees.

Anything seem wrong about this?

Is this a ridiculous yeast choice?

I've done a cold mix before, but I had cooler fermenting temperatures.

I'm looking for something low maintenance, something I can ferment at my average room temperature.

Thanks!

It doesn't seem like a low maintenance yeast since you'll need to follow a good Staggard Nutrient schedule to meet the requirements of the yeast.

it sounds fairly good. not really going to know without trying tho.
need to pay attention to feeding and cooler will be better.
just watch it may take it a bit drier than most others due to low conversion efficiency of sugar ie eats through more honey before it hits alcohol tolerance.

give it a go and tell us how it turns out.

Hum ? Well it reads like it should be.good, though not as low maintenance as, say, K1V-1116.

Plus you'd have to hunt for it in home brew sized packs. Maybe somewhere like morewine!

If you can find it, it sounds like it might be a good candidate for high temp fermentations. Folks are always on the lookout for those.

I would still do your normal nutrient additions, it doesn't sound like a pitch-it-and-forget-it kind of yeast. But the extra glycerol sounds like it could be fun.

Since Fatbloke mentioned Morewine, I went to see if I could find M69 in homebrew size there and I didn't see it, but I recently purchased Lalvins Clos Yeast from them (haven't yet used it) and based on the description it seems like it might be what you are looking for

"Clos is a new yeast strain that was recently isolated in the Priorat region of Spain. Clos was chosen for its ability to re-enforce structure while emphasizing aromatic complexity and mouthfeel. Sweet red fruit (cherry), with pepper and chocolate notes are typical of what Clos brings to a fermentation. With hot climate/high Brix fruit, Clos is a great choice for its high alcohol tolerance (17%), low Nitrogen needs and short lag phase. Clos also does well with higher fermentation temperatures (max 95 F) and shows a good compatibility with MLF. Highly recommended for Syrah, Petite Syrah, Grenache, Tempranillo and Carignane."

High temp and low Nitrogen means fairly low maintenance. You can find it at http://morewinemaking.com/view_product/11425//Dry_Wine_Yeast_-_Clos_8g

Ooh, something else that's not bad at higher temps. Gotta make a note of that one! :)
