You’re doing everything right: tilt, pour, straighten. But your glass is wet from the dishwasher. Disaster. A wet glass dilutes the foam and kills carbonation instantly. It’s like a sneak attack on your beer’s soul.
Always use a dry, clean glass. Some purists even chill the glass—but not too cold. Frosted glasses can cause the beer to go flat or skunk. Room-temp glass, rinsed in cool water and dried? That’s the sweet spot.
