I am in the middle of this do what you want talk. Part of me says, it’s your beer. Do what you want. If you want a pound use a pound. Also, part of me says heed the warning, 1/4# is not that much so if you want some, start small before going big. I know in my experience I usually go big and then I’m like, chit, over did it and now I have to deal with this. So I’m startin to learn that I can start small and do the opposite. Chit, I under did it, next time I’ll use a little more.
I think the Pilsner and Vienna is a good combo, it’s taste will be there but I personally would only be adding Munich for color and a little flavor (same with Cara) , I might scale that back if it were my beer and raise the pils Vienna ratio equally.
You may not have the ability to lager but can keep your beer cool with other methods, wet T-shirt for example, or in a tub of water.
I come to the forum to have it help me make up my own mind. Sometimes people say do this, and I’m like nah, and post my results later and share. Sometimes people say do that, and I had never thought of that before.
Cheers.
