Kim Seung-baek, the 2022 Korea Brewers Cup champion, brews this on a metal V60 paired with the Nucleus Paragon chilling system. The standout is efficiency: just 12g of a light-roast Geisha and 250g at 93°C (1:20.8) — yet the Paragon's rapid chilling traps so much aroma in the cup that a small dose drinks like a much larger one, with a long aftertaste and creamy body. Pour in a thick center-out-center stream, 50g every 40 seconds across five pours, letting the chilled extract concentrate the coffee's sweetness and acidity.
