I am planning to brew sahti, which is supposed to have clove (phenolic) and banana (esters) flavors. They are said to be possible to make with baker's yeast, which I believe is possible for the moment.
My question is whether I should make a ferulic break during mashing to enhance phenols from rye malt (which is about 30% of fermentables) or is this technique only viable with wheat malts? In other words: does rye malt can be source of ferulic acid and if yes, is the ferulic break temperature the same as for wheat?
