I can confirm that according to Brewfather low alcohol, (LA), doesnt necessarily give you low carbs. I've been trying some LA brews recently using the high temperature, (80°C), mash method. To give some examples here are the ABVs and Carbs/100ml for some recent brews. (I dont know how accuarte these are its all taken from brewfather).
LA - a haze for days - 1.6% ABV, 6.4g carbs - this one tasted good
LA - to use up my inventory - 1.1%, 6.5 g carbs - this ones not quite ready yet, but sample tastes good
LA - tropical XPA - 1.1% ABV, 4.7g carbs - this one tasted ok but a bit thin
LA - Lucid moments - 0.8%, 3.8g carbs - tasted thin
London Porter - 5.1% ABV, 5g carbs
SMASH using maris otter - 3.8% ABV, 4.3g carbs
80' clone - 4.9% ABV, 3.9g carbs
I'm happy to share the recipes and method if anyones interested. I got most of the information and recipes from
Ultra Low Brewing - Alcohol Free and Ultra Low Beer Brewing Techniques Other than the 'inventory' LA recipe above the originals are available on brewfather.
