Hello Brewers,

I’ve been testing my recently finished yeast harvesting machine.

The main idea behind it was to design something that would allow home brewers to culture a yeast strain indefinitely, without the inevitable colonisation by wild yeast and bacteria.

Please take a look, if that sort thing is of interest to you.

It’s a closed system for culturing pure yeast and inoculating sterile wort. The air filter stops airborne microbes (wild yeast and bacteria) contaminating the starter wort. The stirred culture is a 1.5L starter (more than I need for a 23L brew). When it’s done, 500ml of the culture is pumped to another 1L batch of sterile wort, inoculating the next 1.5L starter.
