Why do your recipe kits not have water measurements?
We don’t include water measurements with any of our recipes as water calculations are not a general thing that one set of rules will suit everyone. It varys totally depending on your equipment and method. You’ll also find you don’t get water measurements in any decent home brew book also just because of this reason, and its something that you will have to work out according to your brewing equipment and ability. Please check out our blog post which explains this in more detail along with a video.
You can find many online tools/calculators or software to help you work these out like this one https://www.themaltmiller.co.uk/sparge-water-calculator/
