Indeed, it is common practice to use mixtures of simple and complex carbohydrates at mashing, as an adjunct to the malt, to control the fermentability of the resulting wort. Sourness The sourness of beer is, unsurprisingly, due to the presence of acids in the final beer. 4, although some products do extend this range to some extent. The pH scale though is, of course, logarithmic, so that the range of proton activities which this scale represents are from around 40 up to 126 M. e. 5 to 1 M). This has a small but observable effect on the acid dissociation constants of weak organic acids, as might be expected because the dielectric constants of such aqueous ethanolic media will be less than that of pure water and therefore less able to maintain ions in solution.
