“Interesting mate! The JH video suggests >=21% extraction compared to The Next Level at 23%. Of course, he mentioned the cup lacked clarity.”
21% might be normal for a Kenyan, Colombian, or Yemeni coffee, this is meaningless. I’ve had very tasty V60s at 23%… all at typical brew ratios (60-67g/L).
EY is a range, based around an average, You can dial in with a coffee sure, but it’s not a sniping tool.
V60 02 Drip assist: Still honing the technique, but here is where I am as of now:
Coarse grind, 94 on Niche (9% at 400 Kruve, 20% at 600um ASTM/ISO), 13.8g coffee, Pour 7 pulses of 30g, every 30s to 210g total, (each pour taking about 10s), First 3 pours in the centre, last 4 pours around the outer ring.
Medium drip grind 12% at 400 Kruve, 30% at 600um ASTM/ISO, 13.8g coffee, Pour 5 pulses of 40g every 40s, each pour taking~13s…still undecided over whether to pour 1 or 2 in the centre to start, remainder around the ring. Have also been pouring 40g in 30s, 2 inner, 3 outer pours. At this grind I have been using the Kalita 185, 5 pours of 40g every 40s (each~ 13s), 1 inner 4 outer.
Again, Drip Assist brews are a work in progress, so things may change.
