So I brewed my vienna lager recipe with some slight tweaks. The recipe was designed using 4.1 AA Hallertau. Since I order most of my hops online I don’t know the actual AA till I get them. I usually adjust my recipe when the hops get in to make sure im using the right amount. Well I forgot to do that this time. The Hallertau I got were 2.4 AA. So needless to say I will have a pretty malty vienna on my hands (coming in at 11 IBU according to BeerSmith).
