Troubleshooting Higher Esters and Hot Alcohol in a Kolsch

Soft parts are definitely prone to infections if you're not careful

So as long as your parts stay hard, you're fine.

But you gotta keep 'em clean, too.

Yeah, soft parts like tubing are prone to hanging onto things like that. Have you used the filter on anything since?

I haven't used it on anything since. I really only use it with Kolsch and lager yeast - the ones that don't floc. I don't want to chance another batch, so I'm just going to retube everything.
