Any thoughts on how a potential lactose additon would play with that grain bill? A local brewery here in Melbourne that does excellent Oatcream IPAs told me they use 4% lactose in an 8% beer.I'm glad the grain bill and hop schedule worked out well for you! That looks like a really delicious beer!
I just finally pulled the last two pints of mine last night and it held up really well until the last glass (I naturally carbed with CBC1). I really wouldn't change this grain bill at all for an Oat DIPA. It seems like it is a perfect grain bill to play around with different hops and yeasts!
