Posted in thread: Raisins & Gravity Calculation on 08-01-2015 at 03:49 PM
I am working on a beer in which raisins will constitute a good portion of the fermentables (5%
or so). Because of that I'm trying to figure out how to enter them into beersmith to get a

Okay, this is interesting. Multiple older papers cite delbrueckii as strictly homofermentative,
unable to ferment pentose sugars. The published genome for delbrueckii bulgaricus isolate ND02

(b) plate out on appropriate medium to find out what Wyeast and WL are actually including as
pure culture (or not). There are numerous reports of this occurring; indeed, for my yeast bank
I've found m...

One quibble: homofermentative strains shouldn't drop gravity at all besides biomass production.
Even with impossible complete attenuation, the apparent gravity can't go down 30 points.True,
but I was ...

Like Garth said, this is an interesting thread and a great example of confirmation bias. The
concept of a 100% lacto fermentation reaching full (>70%) attenuation has always been somewhat
of a joke. T...

I think that you all panic way too much about oxidation. I always rack to a secondary carboy
full of air, and from the secondary to my bottling bucket without a lid on it, and I've never
had a single ...

RDWHAHB - yeast grow pretty good in wort, your starter will be fine. Nutrient gives you a
little better yield, but that's about it. Adding it now would simply risk infection.B

I hope that is an error, I assume you meant 107.The imperial system is a mystery to me - you
could tell me that 42C is 1,270F and I'd only be modestly suspicious.Actually if you run it
above 110 F, (o...

Like Ed said, if you do want to go this route it would be best to use a flask/container to
contain the dry ice, and to then pipe in the sublimated CO2 using sanitized tubing. Plus, as
