Brewer to Brewer: Rowan van Dijk and Davide Callegari

Rowan van Dijk of Moersleutel interviews Davide Callegari of Brew York. This Episode is Sponsored by: Berkeley Yeast Our Tropics yeast is based on a London Ale strain, but we added a new gene to its genome that codes for a unique thiol-releasing enzyme. The enzyme converts the precursors in barley to free thiols that smell and taste like passionfruit and grapefruit. It’s super clean. No off-flavors like burnt rubber or other sulfurous notes. Just tropical aromatics. You don’t have to do anything unusual either, like mash hopping. Just pitch dry Tropics and supercharge your hazy IPA. Sennos Sennos is redefining fermentation intelligence. Their new SennosM3 is a multi-parametric, in-tank sensor that delivers real-time fermentation insights and predictive analytics—so brewers can monitor critical variables, catch issues early, and get consistent results every batch. Brew smarter, waste less, and profit more with Sennos. Turn your tank into a smart tank.
