Low abv beer

[Dark Arts]

Look up home to make zero beer, basically make you beer per usual method(maybe use less fermentables as well) then when your all fermented stick in a pot boil off the alcohol 80°ish? Not sure how long per abv to remove etc but thats the gist from the article ive just read.......or just buy it

Not much to go on̈ but heres my notrs

I have discovered accidentally that adding an extra litre of water to a beer kit does reduce the ABV amount… did a coopers larger and added 1 litre more than I should have!!! ABV went down to 1.5… I did manage to increase it up to 3.5 by fermenting an extra week with 500g of sugar added.. all turned out well in the end… so, yea. If your using a beer kit, if it says add 23 litres, add 24 or nearly 25 litres… That should sort out the alcohol levels in your beer by reducing the ABV for yea

Brilliant, thank you.

Brilliant, thank you.

I can't see how 1 litre of water in 23 would make much difference to the ABV. There's a dilution calculator here where you can work out the exact amount based on the amount of extract you're using.

No I can only assume either a hydrometer mis read, or an incomplete fermentation based on time rather than gravity reading.

I've done a few low alc AG brews using 300-500g base malt in 20l and what I have found is they take an absolute age to drop clear even using S04 yeast, it takes as long to clear as a 4% wheat beer using S33 yeast.

this has a whole section on the different methods of achieving low abv beers, looks interesting.
