So I finally got to brew with the XF, and for the first time impression and first time making pour over ever myself. I was very thrilled with the results.
I did a +6 on my Lido 3 (6 tick marks away from zero) with 20g coffee and total of 280g water. Ended up being a ~2:50 brew time. I just started with a 40g bloom for 30 seconds and went with slow circles until reached target water weight. I then let it drip all the way through. It was pleasant to drink, a bit underextracted actually, had an acidity that shouldn't be there with this blend (Campfire Blend by Lofty Coffee) IMO. I'll grind a bit finer next time I guess.
I am excited to try to make an Ethiopian Guji in the afternoon once I get done from school.
Made another small batch. 20g beans, 300g water, finished with 3:20 brew time with 30-sec bloom. The grind was a little bit finer this time and the cup was very very good. Very similar to the cups I've had in shops and they use a modbar for their water source and brew on Kalita Wave. Bright, juicy, hints of blueberry and red raspberry acidity.
