Re: Brewing alcohol free

Had a listen to that podcast and after the back slapping and shite talk you get to 30 minutes where he starts to chat about their mashing schedule. He mash @ 52C for 40 minutes and then quickly brings it up to 74C for 60 minutes. Sparge @78C. I'd say the 52C is for the limit dextrinase phase first t...

Re: Brewing alcohol free

On the search for yeast that eat maltose and not maltotriose you can look at Windsor. On the spec sheet for this yeast it states that it cannot deal with maltotriose.
My other research suggests PH 5.5 in the mash favours alpha more than Beta amylase without compromising the wort.

Re: Brewing alcohol free

I was chatting with a commercial yeast specialist who said he would not release this yeast for legal reasons. Said that the brewery using it would need to be super sterile and as most brewerys are not then a high degree of spoilt brews can ensue. I note from the 2 research papers we listed both had ...

If you want to slant it then have a pot of coffee on stand by and have a read here. The yeast I mentioned is commercial but the other yeast listed here is not.

Re: Brewing alcohol free

The yeast mentioned in the above article is here. My thinking about adjusting PH is referred to in it. They recommend mash PH is adjusted. My thinking outside the box is working. Now if I can get back in the box that will be progress. https://www.hefebank-weihenstephan.de/en/products/yeast/spezialhe...

Re: Brewing alcohol free

By raising the PH of the liquid mash you don't have the grain husks only the wort so extracting tannins should not be an issue. :?:

Re: Brewing alcohol free

We had our 5th Brecon last Saturday and a talk by WHC, a yeast provider who said he has a strain that only ferments a small range of the sugars available. He said they will not release it as brewerys who may us it would need very clean packaging as any bacteria would attack the remaining sugars.

Re: Brewing alcohol free

To help with the burnt issue I presume pre filtering before boil might be best.

Re: Brewing alcohol free

Being thinking about the issue of encouraging alpha amylase instead of beta. Under normal mashing at 64c/68c range we tend to opt for the low 5 PH range but in the cold mash scenario to produce low fermentables with some dextrins I'm thinking about flaring PH. Beta likes it best between 4.0 to 5.5 P...
