Why you need this device Creates a richer, longer-lasting hop foam that lifts aroma and improves the taste of your beer by using the beer’s own carbonation. Consistent, bar-quality foam without complicated equipment or manual pouring techniques. One-step operation makes serving beer faster and simpler for home use, events, or outdoor gatherings. How it works Ultrasonic high-frequency vibration at 40,000 vibrations per second agitates dissolved CO2 and activates hop foam, producing a dense head that enhances aroma and flavor. The device harnesses the beer’s natural carbonation to generate stable foam rather than adding ingredients or changing the beer. Key features and specifications Ultrasonic vibration frequency: 40,000 vibrations per second. Simple one-step piston operation: choose between foam or liquid output as needed. Compatibility: fits full beer bottles and cans up to 500 ml (maximum diameter 68 mm, maximum height 290 mm). Durable materials: high-quality ABS outer shell, food-grade silicone tube for hygienic liquid contact, and a smooth vacuum-coated plunger for reliable motion. Disassembly: all parts except the upper head can be removed for cleaning. Practical benefits Easy to use: place the bottle or can into the device and operate the piston in one step to create a rich head or pour normally. Hygienic and safe: food-grade silicone components in contact with beer; robust ABS casing for everyday use. Long-lasting build: materials selected for durability in repeated home or outdoor use.
