In both the water calc & mash water pH adjustment tools please allow the brewer to pick/insert the acid % rather than select from a predetermined list (or increase the available options). For example 85% & 96% Phosphoric Acid is readily available in many brewshops as a means of adjusting pH but only the 10% option is available in the list.
Also a small typo - Within the Mash Water pH Adjustment tool the word ‘Adjustment’ is spelt incorrectly.


Hi Michael,
This is currently on our roadmap. We’re aiming to release this in the next app update :)
You will be able to customise the acid concentration after that.
