Did a kettle sour for the first time. Boiled it for 20 min before pitching lactobacillus plantarum and kept it at 100F for 2 days. When I opened the kettle I noticed a pellicule and some people ask me if there's was brett and no. I taste like a sour and no taste of brett. Is the pellicule normal in a sour kettle?
Cheers,
