The Hario V60 02 is the most widely used pour-over brewer in specialty coffee. Introduced by Japanese glassware maker Hario in 2004, its name comes from the sixty-degree cone angle that gives the device its distinctive silhouette. The 02 size fits one to four cups and has become the de-facto benchmark most modern pour-over recipes are written for.
Three design choices define the cup. The 60° cone concentrates the coffee bed and lets the slurry fall toward a single large hole, giving you direct control over flow rate. The tall spiral ribs prevent the filter from sealing against the dripper, allowing air to escape and water to drain evenly. Together they produce a brew with high clarity, articulate acidity, and the kind of floral or fruity top notes that define light-roast filter coffee.
A typical V60 02 recipe uses 15 g of coffee to 250 g of water (1:16 ratio), a medium-fine grind, water at 93–96 °C, and a total brew time between 2:30 and 3:30. The method rewards technique: a strong bloom, controlled pour spirals, and a flat bed at drawdown are what separate a good cup from a great one. Canonical recipes to try include James Hoffmann's "Ultimate" V60 and Tetsu Kasuya's 4:6 method.
