Coopers commercial yeast method

[PaddyBrew2]

Harvesting the yeast from the 6 pale ale stubbies. What kind of gravity can this method handle. I’m thinking of doing the toucan stout soon. Would the yeast from 6 stubbies handle this OG?

I’d go more paddy for anything over a 1050 OG brew. The other and better way I think is get a sanitised 2L water or coke bottle and make a starter in it.

Isn’t that what it is though in effect , a starter?

I would say that six coopers bottles gives a big enough starter for a standard, sub-1050 OG brew.  The 2019 Coopers Vintage says to use the Commercial yeast starter plus the brew can yeast.  It is effectively a toucan plus 1kg dextrose.

Cheers mate. Will give it a go

Make it the way with the bottles and sugars in each of the bottles. Once they get active put it into another solution of about 1.8L (preferably malt based) in the 2L bottle. There you have a stepped starter and will be plenty enough yeast.

Cooper own strain will ferment concrete slurry. 

It's a beast
