A person or machine that produces, processes, or deals with buckwheat grain.
From 'buckwheat' (a grain crop) plus the agent suffix '-er' meaning 'one who does or makes.' Buckwheat itself comes from Dutch 'boekweit,' literally 'beech wheat,' due to the seed's resemblance to beech nuts.
Buckwheat was so important to European agriculture that it got its own occupational titles—the fact that 'buckwheater' exists shows buckwheat was commercially significant, not just a subsistence crop!
