Oh , I see your OG now . Thats a big beer. I see what your getting at . You could have made a hop tea , but since you've already bottled your stuck with what you got im afraid of .
Just serve a massive IBU IPA to your buddies first then follow with the red 😀
If you have intertap faucets , then yes you can buy the stout tip. Beer gas comes in a different tank then co2. I have 75% 25%. I have a specific regulator for that tank as well. I think its different then the regular co2 tanks .
Thats my process. I learned that here . Do you have to ? No I wouldn't say you have to. However I always leave beer in the fv for 3 weeks and this process puts me right about there.
I also slightly carb at the tail end so if I don't have an available keg I can sample from the fv
