Most coffee lovers toss a pour-over once they realize the grind size is off, but James Hoffmann reveals that you can actually save a bad brew mid-pour. Whether your water is stalling or racing through the grounds, simple adjustments to timing and agitation can salvage the flavor profile. Learn how to stop a fine-grind disaster and rescue a coarse-grind failure without wasting expensive beans.
A stray pebble in your coffee bag feels like a death sentence for your expensive grinder burrs, but the mechanical reality is far more forgiving. We put high-end grinders through a gauntlet of wood, stone, and metal to see what actually breaks—and the results might save you from an unnecessary burr replacement.
The coffee siphon is a theatrical masterpiece, but beneath the bubbling glass lies a chaotic world of thermodynamics and vacuum physics. New data from custom-built sensors reveals that much of what we thought about siphon pressure and stirring is wrong. While the 'draw-down' looks like the main event, the real secret to a perfect cup happens in the invisible insulation of the coffee crust and the subtle shift of negative pressure.
Cold brew is often a wasteful process that sacrifices flavor for convenience, but new research suggests we've been doing it wrong for years. By borrowing a secret technique from professional winemakers, it's possible to use less coffee while achieving a significantly more complex and cleaner cup. Discover why your choice of bean roast might be ruining your chilled coffee experience and how a simple change in grind size can fix the most common flavor problems.
