Brewing alcohol free
« on: April 10, 2019, 02:27:14 PM »
Some time ago I heard that the big brewerys were involved with research into a new strain of yeast that can ferment a wort but not produce any alcohol. If such a yeast can become viable then the whole new world of beers that taste like beer with no alcohol would truly take hold. However try as I have I cannot find any information out there  . Anyone know anything

NEER yeast. Read about it a while back, patiently waiting.

Apparently there's a small % of this type in all strains so some part of your beer is already fermenting with no alcohol by product. Think the trick is now to make it its own strain assuming there's no biological co-dependency factors etc.

A technique that may work would be to produce a high temp mash and after boil to starve the wort of any oxygen and to ferment at 2 to 4 C. Anaerobic yeast growth will happen which should inhibit ethanol.

Why are posts 3 and 4 empty?

Works fine on Tapatalk, probably doesn't agree with the web forum

I am thinking about releasing a 'non alcoholic' yeast . There is a pair of them that do the job that I have been looking at.

Basically they can ferment fructose, glucose and sucrose but not the other constituents of the wort. If you start with a 1.023 gravity it should finish with about .5% ABV which falls technically into the non alcoholic category. Do you think this is something homebrewers would be interested in/?

I'd give that a go. Would it produce a watery beer? Your 1.023 example would only drop about 4 points to give 0.5%  abv. Would it be as simple as substitute this yeast for us05 in a simple pale ale for example?

It would be actually more on the sweeter end as there is still a lot of residual sugar unlike most not alcholic beers which can be watery. If you used the yeast in too high of a starting gravity it with will be way too  sweet due to small attenuation of the yeast and therefore the amount of sugar left behind.

So brew a beer (a pale ale for example) to about 1.018 and let it drop to about 1.014 and keg? Hmm, could be worth a try so long as the body of the beer is ok

Would like a bash at this yeast too. Liffey Brewers meet at end of month be a good place to chat about this GREAT yeast. :-*

I'd be interested in something like this also.

The high finishing gravity reminds me of Guinness' non-alcoholic ale. A bit sweet but I'm sure that comes with the yeast. Kinda wondered how they did it
