Estate Series – Malbec, Argentina 10L (Red)

This is a very simple way to check the alcohol content of your home brew wine but remember – it is very approximate and you need to know how it works to avoid the common pitfalls.
It works on (still) wine only, not beer or spirits.
It will only work if there is no CO2 left in your wine.
It will only work if your wine is 8-13% or around these values
