    I've tried using the water calculator to hit my intended mash pH. I've been using Bru'n Water and also Brewer's Friend and the two give really different outputs.

    I think the difference is down to the Brupacks Carbonate Reduction Solution (CRS) that I'm using with the mash water. Brewers friend lists the two components as 6.4% Hydrochloric and 8.6% Sulphuric acid. There is then the acid strength option below which is set to 100%. Should I adjust this to be 15% as the combined strength of the two constituent acids, or should I leave it at 100% as it is already taking in to account the percentage strength of the acid?

    Thanks, Simon

    Same question here, thank you

    EDIT : Sorry it seems it's been answered in the FAQ : "This mix, also sold as AMS3, is popular among UK home brewers. A strength of 100% refers to the strength of this acid in the bottle."
