Had a Pina Colada IPA for the first time yesterday. It was pretty damn tasty. The coconut was there in a subtle way. Would like to to make an attempt at brewing one. I've checked out a few recipes and most add lactose. Is lactose a necessary component for a pina colada IPA or even just a coconut IPA? I would be ok just going with my usual NEIPA recipe and just adding in coconut towards the end of fermentation. If the coconut is added during fermentation, would there be any concern about infection? Thoughts?
