Transform any canned or bottled beer into a rich, creamy draught experience. Powered by 40,000Hz ultrasonic technology, the HopFlowir creates a dense, authentic foam head that locks in flavor, reduces bitterness, and keeps your beer ice-cold anywhere with its built-in sub-zero cooling medium.










Standard beer pours lose their carbonation and aroma quickly. HopFlowir uses micro-foaming ultrasonic vibrations operating 40,000 times per second to build a dense foam head. This natural barrier seals in the rich malt aroma, reduces bitterness, and prevents oxidation for a smoother drink.
Warm beer ruins the outdoor experience. HopFlowir features a built-in sub-zero ice pack designed to keep your favorite lager, ale, or stout perfectly chilled during barbecues, camping trips, picnics, or sunny beach days.


Heavy draft setups are a nightmare to clean and carry. HopFlowir weighs just 1,210g and features a modular, detachable body made from premium ABS and titanium. Simply disassemble, quick-rinse under running water, and you're ready for the next perfect pour.



"The HopFlowir is a masterclass in beer tech. By replicating the exact micro-bubble density of professional pub taps via high-frequency ultrasonics, it unlocks flavors in canned beer that consumers didn't even know existed. It's an absolute must-have for any beer connoisseur."
– David Vance, Research Specialist
