In almost every interview on The Seed Farmer, my guests and I wind up talking about tools. And one tool that podcast guests have mentioned more than any other tool is the Winnow Wizard. We use the Winnow Wizard at Torne-Sol Farm to clean seeds, so I understand the love that folks have for this machine. But I really wasn't expecting it for it to just keep coming back, interview after interview. And since it has kept coming back, I thought we should spend some time with the person who designed the seed cleaning machine, Mark Luterra. Mark currently works at Adaptive Seeds in Sweet Home, Oregon, but he started his seed journey at Wild Garden Seed, where he designed and built the first Winnow Wizard to make his seed cleaning days easier. He then went on to build another 104 machines that have been shipped all over the U.S. and Canada. He's now transferred production of the Winnow Wizard to Oppen Works in Wisconsin. In today's episode, Mark tells us what the Winnow Wizard does and how it works, and we do a deep dive into seed cleaning. And of course, the Winnow Wizard plays the key part in the seed cleaning stories, but Mark also explains how seed harvest and screening are equally important steps to get your seed clean. Mark also reveals some secrets of using a shop vac for seed cleaning. During the discussion, we go through four seed cleaning scenarios and how Mark would tackle each of them. Mark then wraps up the conversation by telling us about his next seed project aimed at small-scale seed farmers.
