I save up a 50ml shot glass full of ABV and dump it all into a small blender quart sized smoothie when the time comes.
Strawberry yogurt, fresh strawberry, frozen banana, vanilla icecream, and a scoop of peanut butter, and your prefered kind of milk. These ingredients do nicely to mask the ABV taste and get the liquid slosh down the gullet easy.
I didn’t measure how many Gs of abv but I estimate about 10g of ABV was used I’ll try to scale it if I make this kind of post in the future.
A friend gave me the idea actually, I was using it or giving it away for years before I started composting it. All I use is half of a wooden barrel with a hole in the bottom of it. I dump all my ABV and yerba mate leftovers into the barrel every day and mix it around/add water sometimes. After a couple weeks it’s more or less dirt again lol. Sometimes I mix it into recycled soil, sometimes I use it as is. Just depends on what’s being done.
