Shownotes
How do decisions made on the farm show up in the cup? Today we’re joined by Nicholas Rae, Head of Coffee at Toby’s Estate, who has been working to answer that question through specialised coffee research.
Toby’s is one of the few roasters to have a research plot, almost a hectare of land at Daterra Coffee Farm in Brazil. It’s here they investigate coffee processing, specifically how water composition during fermentation impacts coffee flavour. So… What happens when you treat coffee with minerals, does it increase the cup score, and ultimately, do these findings have the potential to change the industry?
Much to consider!
If you're new here (welcome), our show dives into some of the best coffee conversations on the internet, but we will always remind ourselves at the end of the day - It's Just Coffee!
