In this episode of the Specialty Match Podcast, hosts Ryan and Zongjun (Sam) delve into the world of matcha milling. They explore various milling mechanisms, including traditional stone-ground (ishi usu) matcha, and modern approaches such as ball mills and jet mills. The conversation highlights the operational complexities of these machines, the importance of particle morphology and heat management, and the grinding mechanisms of each method.

Additionally, they announce features of the matcha mill they are currently developing, Sanko Usu One, to mill matcha fresh anywhere and everywhere to a similar quality standard of a traditional stone ishi usu. For more information on Sanko Usu One, please email hello@sanko-cha.com or message us on Instagram @sanko_matcha or @specialtymatcha for a link-only Notion page with all of the details .
