Please join us from the USA, Monday, October 2 at 8 pm EST, for a virtual webinar featuring 2022 Daphne Zepos Teaching Award recipient Trevor Warmedahl.

Trevor spent the bulk of 2022 researching the world of coagulants in cheesemaking. He dove deep into traditional rennet extraction in the cheesemaking communities of Sardinia, the Canary Islands, and throughout northern Spain.

Trevor first presented his findings at the American Cheese Society conference in Des Moines in July 2023. He covered the gamut of rennet production from the farm level to the industrial. He also reported on the different sources: animal, vegetable, and synthetic.

If you are looking to expand your knowledge of rennet, this is the event for you.
