This video offers a full kveik yeast harvesting guide. This guide will show you how to reculture kveik yeast from liquid or dry form all the way through to liquid or dry form again. This is ideal for ensuring that you never run out and have fresh kveik to use. These methods also work well for regular yeast.
There is a great deal of advice, hints and tips in this video that I hope you find very useful.
