Need to Boil after Mash Out?

Need to Boil after Mash Out?

Postby Toddy » Sun Aug 14, 2016 11:36 am

After Mash out do we need to do the "Boil" before running through a plate chiller directly into the Fermenter?
I don't think they do a boil step in commercial distilleries? (could be wrong here)
I know the boil kills off any nasties (wild yeasts etc.), but would going straight into the fermenter from the mash tun and adding yeast asap alleviate this problem?

Thanks.

I always gave it 10 minute boil in the past but lately I haven't bothered. I always sanitize the fermenter and run the batch as soon as it's cleared and so far I've had no problems. I'd say try without and see. :obscene-drinkingcheers:

No boil needed for grain washes.

Or looking at it another way.
If it is going to foam up it will do so. Do you want it to do it in your still boiler, and has it got the headspace to cope with it?
Might be convenient to boil before cooling to fermentation temp, but if not take it into account later.
