D47

[Vlabruz]

In making a mead that started at 1.114 sg I believe d47 is a 14% yeast. Does that mean that it will die off and the mead won't go below 1.007ish or it still can? I assume ill need to take readings looking for it to be stable?

The published limit of a yeast is an average from a laboratory setting. Your actual results can be higher or lower. If the fermentation stops where you expect it, I'd still bulk age at least 6 months to help ensure it's really done. @Rice_Guy reports that aging 9+ months starves the yeast, and he does not get a renewed fermentation.

You can add sorbate and k-meta to ensure the fermentation does not restart.

Note that members have step fed EC-1118 (tolerance 18%) up to 21%.

I've been step feeding this fermo so i guess ill see.

Please report your final results.

Time is your friend. By the time you hit the limit, it's highly likely it won't restart, although I'd still bulk age to ensure that.

Mead? there is a slug of non-fermentable sugar in all honey so “normal” number with sucrose/ glucose/ fructose don’t apply. It might wind up at 1.007 and maybe not, we all monitor to see when readings are stable. ,,,, A healthy mead has several nutrient additions as Fermaid O and Fermaid K, we’re you adding honey (sugar) to step feed or nitrogen? I hope you were doing nitrogen since a single DAP feeding probably will crash. We have other variables as a slower ferment is less likely to get stuck and organic nitrogen is less likely to get stuck.

I pitched yeast with fermaid and have be step feeding with ferm-0.

I've had D47 get to 14.8% in an faux ice cider I did -- and No nutrients were ever added...just 100% AJ & FAJC.

Good luck & Cheers!
