So I played with natural yeasts and cultivation. Had few strains isolated and kept in fridge. But recently one extremely resistant strain contaminated all of it.

Had some good brews, some bad, some meh. So what is yours experience, did you tryed it or want to?

    That sounds like a nice weekend project. How do you isolate the strains? Do you make an agar plate and just spread around and then grow the colonies you like?

      Weekend? It takes several weeks. You have few options to capture them - wort with fruit/leaves in mason jar, agar plate, wort sitting outside. Then let it ferment for 2 weeks, spread on plate, in incubator for 5 days. Then you take single “colony” repeat fermentation and agar plate step.

      You don’t need special equipment just some Petri dishes and optionally incubator. For agar I made my own from wort. Everything is sanitised in pressure cooker.

      After you have single strain on agar plate/tube you then have to propagate them and brew with it.
