Notes

Experimental brew comparing use of non-toasted koji rice/mugwort vs toasted koji rice/hops for effects on flavour, body and head retention, as well as the citric acid level as a by product of the koji

koji strain: Aspergillus kawachii (non pigmented strain of black koji)

Will update recipe when brews are completed, or as I go during the process

Oh, this is my first beer. I take no accountability for terrible beer if you attempt this recipe
