I have been nervous about running this test for months, which is why I did it within moments of arriving home with the first Black edition production unit. A/B testing to check that performance of the new Black model matches up with the Walnut model. Swipe 👉 to see and swipe👇 to read details.
1. Grind setting 10 @Baratza Encore both units
2. 17.0 grams of coffee both units (a fresh and tasty Rwandan by @Almanac_Coffee)
2. 250 grams of brew water at 94 degrees both units
3. 1 x paper filter rinsed thoroughly both units.
4. Start timer and add water simultaneously.
5. Immerse until 45 sec elapsed.
6. Open valves simultaneously.
7. Add press cylinder simultaneously.
NB. Both have the new Gen 2 brew chamber (available soon for both models), the Walnut model is otherwise 1 year old.
1. Total brew time was 1:29 for Black and 1:31 for Walnut (very close!)
2. Yield was 238g for Walnut and 239g for Black. Amazing consistency.
3. %TDS was also very close at 1.03% for Black and 1.06% for Walnut. A touch light in strength for both as I started press a bit too early for the test, and the ground coffee didn't seem to absorb a lot of moisture (high yield). Overall it was incredible to witness such precision and consistency in press time, brew time, yield and relative brew strength between the two units, especially as it was literally the first test undertaken on the new model fresh out of the box. More testing to follow, but as always, It's promising that it looks like consistency is something unique on Trinity, and now for models 1 and 2 combined.
