Pour-your-own tap walls and table taps, metered so the guest pays for what they pull rather than by the pint. The argument for them is always the same two things: no queue at the bar, and people trying beers they would never order a full glass of.
Guests pour their own beer and are charged by the volume poured, against a card or wristband that staff activate at the bar.
They cut bar queues and free staff at peak; you still need oversight for age checks and line care, so treat it as redeployment rather than headcount removal.
Tap walls suit high-traffic venues, table taps suit group seating, and mobile kegerator counters suit events or overflow bars — send your layout and we'll match it.
Power, a drain, a chilled keg supply within line reach, and a network connection for payment; some units carry built-in refrigeration for up to 16 kegs, which changes what you need to plumb.
You do, at the point where staff activate the card or wristband — a self serve beer tap checks credit, not age, and most venues also cap the volume one card can pour.
A self pour beer wall meters what each guest pours against a card or a wristband, so drinks are charged by the millilitre. A self pour tap system cuts the queue and the over-pour at once, and the reporting shows exactly which keg is selling.
