This evening I'm in the middle of brewing a 'Cerveza' style with 4k of BB Galaxy Pilsener with 1kg rice as an adjunct. I was browsing on the UK site for Bairds malt and they say for two of their products:
Pale Ale Malts: ...........Even with a diastase of only 45L there is still enough activity to convert for example 5% of Crystal malt and 5 -10% of cooked adjunct (e.g. flaked maize).........
Premium Pilsener Malt: .........Although mainly intended for all malt beers, there is sufficient diastatic power to convert a limited amount of adjunct. Care will have to be taken that too much adjunct is not used or flavour could be impaired. Also, excessive dilution of soluble nitrogen could result in yeast nutrition problems, causing poor fermentation or flavour defects due to diacetyl for example.
Now it seems to be common wisdom on the forum here that you can whack in heaps of adjunct with Aus malts and as you can see I'm using 20% adjunct tonight. However I have done a few adjunct brews with UK Thomas Fawcett MO and GP using 500g of maize to 4kg of malt .. that's around 11% so just out of range, if TF is similar to Bairds in this respect, and have been getting a bit of diacetyl, which personally I love in moderation. I'm currently drinking my way through a Modern Summer Ale with 500g maize and its nice and buttery :icon_cheers:
I'm wondering if there's any hard information on how much adjunct Aus malts can handle?
