Different opinion that no one Will agree with. 05 was my go to forever then I was hearing a lot of recommendations for 97 so I have used it in the last handful of batches.
In my experience, 97 is more sluggish, slower to clear, and leaves a bit more body. I find 05 to be more dry and neutral. I’ve never got the peach thing from 05 but just assume it exists at this point.
I think lallemand also promotes 97 as a strain capable of bio transformation
I’m not sure I have a preference and would use either depending on the circumstances.
