Whoa, iPad typo fail. I have an amber in primary that I mashed with 9 oz. hazelnuts. Anyone added tstd hazelnuts to secondary? If so, how much and how was it added. I am thinking of either adding cold steeped liquid (3-5 day steep) or just crushing and racking onto. My main fear is oils causing lack of head retention. However I will be kegging , so not sure if oils matter. Any thoughts/insight are appreciated.
