Random Brew Recipe: 37g coffee / 1 kg water, 4 minute brew time.
Brew Method: Bonavita into Chemex
Actual Recipe: 37g coffee, 1 kg water at 200F
Coffee: New Harvest Coffee Roasters’ Rwanda Coko
Notes notes notes: This coffee I am fairly familiar with. It’s offered by a few roasters, each of whom have their own take. One of our employees recently competed in the NERBC using this coffee. It is actually going to be our first single-origin retail offering as well – so I’ve had this coffee a time or two. As such, it seemed like a good chance to use the RBG with a familiar coffee and an unfamiliar method. So, I used the Bonavita in the lab to brew into a large Chemex – and the 37g of coffee looked like a woefully small amount.
I was expecting the combination of a low throw weight with an odd brewing system to produce a washed-out cup, with much of the brew water passing the coffee entirely and what was left overextracting like crazy. As you can see in the photo, the Bonavita did not overfill the Chemex, though it kept the water level higher than I would have if I were brewing it by hand.
Honestly? It was tasty, and not unlike what I would have expected from a low dose using a special kettle. I shared with the incoming espresso training, and they liked it even more than I did – calling it ‘subtle’ and ‘tea-like,’ which are accurate descriptors. It had the same melon sweetness at the finish that New Harvest’s Coko always shows, as well as an awesome clarity – body, was lacking, but the combination of low dose and hearty Chemex filter probably had something to do with that. I’m going to play with this brewing combination a bit more – though with less random inputs, perhaps.
I’d give it a 7/10. It’s delicate and sweet and subtle, though a bit simple and thin.
