Not anymore but they have done a expansion and they offer courses now for all kinds of things so you get value. We did a fermentation course for food last year. NoneUsed to be that Bok singing tower was a free area of course I am going back to the early 60's so much has changed. I did love it there
Besides long term storage, the fermentation is really healthy for your body and healthy digestion. My wife has always had issues with digestion and this helps her dramatically with all the healthy bacteria it creates.I dry food and have made wine but have never looked at fermentation of food, what is the purpose of it?
