Like the ballon idea. I’ve only seen people who made what’s called prison win use balloons. When it’s time for more yeast I’m going to try that kviek yeast. Northern brewer now sales that brand. They are still hit and miss but they are getting better
Those Kveik yeasts have been fun to use. Good luck with your brews. The goal of the balloon is to gather CO2 to prevent sucking back air or sanitizer while cold crashing. I know there is an article on Brulosophy, but I originally saw the idea on Homebrew Talk: www.homebrewtalk.com/threads/prevent-oxygen-during-cold-crash.662552/#post-8527464
In the sample I tried before dry hopping, I got a bit of a banana flavor (classic bubblegum flavors are a mix of banana and strawberry flavors). If it is there in the final beer, it blends in with all the hop flavors. I get more of a touch of a clove character, especially in the aftertaste.
