If you are talking about the Uvaferm... I think we source that from winequip Melbourne.

Can that stuff be used to restart a stuck UJ ferment or only neutral??

If you have hit a wall...I find it the best last resort yeast....so yes, it can save a batch that may otherwise be lost... it just does not bring out the fruity esters that a good old ale yeast brings to the table.

What quantity of yeast do you use i take that what applies to making beer does not apply like the higher temperatures and at higher temperature would ferment quicker and if do not boil and do not kill off all the enzymes could there be more slow conversion by any leftover enzymes at the lower temperatures.

with Safspirit malt we use 26 grams to 50-60 liters...with Uva ferm we pitch 250 grams to 1000 liters.

we make a starter wort and grow our yeast colony then pitch at around 30 degrees...never had a stuck ferment or a bad batch in hundreds of thousands of liters...but make sure you feed the yeast we use Go - Ferm and Ferm - Aid....not sure what your implying but as a commercial distiller absolute success is getting every ferment to dry....which we do daily.

Ok i get it if you are making yeast starters :handgestures-thumbupleft: but without starters 26g dry yeast in a 50l wash is a heap of yeast :scared-eek:

Hey doc, if you dont mind me asking, in the case of a sour mash when the grain bed/yeast cake are re used, and a "finishing yeast" is used, when the next gen is added will the "finishing yeast" take over the next gen and over power the the wanted yeast say safspirit american whiskey?

Is it better to ditch the cake and grain bed when a finishing yeast is needed? :-B

IF you are referring to using Uva ferm as a rescue yeast...there is no need to get rid of the settled yeast cake... Uvaferm is a dominent yeast...it will out compete safspirit malt and take over the ferment... I hope that is the answer you were gunning for.

I think he was referring to using the yeast cake in the next wash.
As you mentioned it's a dominant yeast I suspect he has his answer though.

I was hoping it was subbmissive so it could be used alongside the malt yeast. Malt yeast does the bulk of the work then uvaferm finishs off. I guess in this case re using the cake would not be benificial. Thanks for your help doc :handgestures-thumbupleft: and coffee..

Unless you killed the yeast cake with boiling water and then added new yeast...

Hey doc have you tried the new "uvaferm restart" yeast. Apparently a new product. I am sticking with the uvaferm 43 this time around but interested to hear if you have used the new one...
