alcohol free brew

Unread postby Onthebrew » Tue Feb 19, 2019 1:32 pm

In effort to cut down a bit on alcohol, i am looking to brew an alcohol free brew ( i know, don't start!) for when i am being good. I quite like brew dogs nanny state, and much prefer that to any regular soft drink, so will have a go at that. My worry is with such a low grain bill (circa 1kg) i am gonna get a few side issues - not even sure the BM can handle such a low grain bill.

one option would not to use the pump, do it all on manual and just let it seep( like boil in the bag)- i would maybe up the grain bill 10-20% to allow for loss of efficiency. anyone any advice? what about yeast- must be minimal id guess?

You might like and experiment with the style the German call - Malzbier - (Maltbeer)
It's very low in alcohol, not more than 0.5 % and is regularly given to children and
pregnant and nursing mothers as - Nährbier - (Nourishment Beer).

Good shout. I will have a go.

The BM doesn't worry me. I reckon my silicone seal around the top will hold it.

Equally I reckon, do it on manual. 66c for an hour. Turning the pump on occasionally to 'stir'.

Alternatively with only 1kg. Put it in a mash bag first.

I reckon 1/2 the yeast.

What grain mix through??
Flavour it going to need to go a long way?
Let's get a recipe going.

I am going to do some research.....

Just a thought, how about the dilution of a normal beer. Brew a rather small beer (like 10 Plato - SG1.040), yet heavy on flavor. Malty via caramel malts/low attenuation via high conversion temp and/or hoppy by higher bitterness, large whirlpool/dry hopping.

A 10 plato (SG 1.040) wort would end up around 4% ABV (with low attenuation due to high dextrine content).
As per the below calculator, mixing 10L of that flat finished beer with 10L of cold (previously boiled water to sanitize it and remove dissolved oxygen) and you have 20L of a 2% ABV beer.

The flavor balance will be tricky but I guess after a few trials, it could work.

The advantage is that it will be rather simple, normal brewing/fermentation process and water addtion at the end.

I recently brewed a 2.6 % mild which turned out very well. It drank like a 3%+ beer. I used a low attenuating yeast, mashed slightly higher and the recipie included Mild Ale malt, special B and 17% porridge oats which boilstered the mash thickness up a bit/ beer body. I was expecting it to finish a bit sweet but it didn't. The beer finished 1st in our recent club low ABV challenge ( less 2.8%)

For a low alcohol beer < 2.8% use a lightly kilned malt such as Vienna or Munich instead of your usual base malt and high mash temp and low attenuating yeast as mentioned above.

For a non-alcoholic beer <0.5%, you're probably better off making a low alcohol beer and then cooking the fermented beer at 85c for half an hour to drive off the alcohol. It probably won't taste great as all the flavour will cook off too - but it would be an interesting experiment. I suppose you could dry hop afterwards in attempt to add some flavour back.

Why a higher mash temp ?

A higher mash temperature will produce more unfermentable dextrines, resulting in a sweeter beer with perceived increased mouthfeel/ body ( and a lower ABV)

Could use 10l pipe, but fill water to the brim.

Malzbier tends to just taste like unfermented wort.

Yeah I get that - but low alcohol beer with a sweeter finish beer is surely similar on calories?

Quite. Depends whether the OP was thinking about his liver or his waistline!

haha it would have to deliver on both to be worth the effort!

a can of brew dog nanny state is only 36 calories and 0.5%. id hope to keep those stats with my version!
