Draft towers and countertop taps with a stout faucet and onboard nitrogen. The cascade is the selling point: a nitro coffee poured through a stout faucet settles in the glass the way a Guinness does, and people film it.
Nitrogen — forced through a restrictor disc in a stout faucet, it drops the cascade and leaves a dense creamy head; plain cold brew on tap pours flat.
Not always — some models carry an onboard nitrogenator and run from air, while others take a gas cylinder like a stout line. We'll confirm which a given nitro cold brew machine uses before you order.
A countertop unit suits a cafe adding one or two lines; a tower with its own chilled keg suits volume and reads as a bar. Tell us your peak hour and we'll size it.
A nitro cold brew dispenser is the tower and the gas; a nitro coffee tap or nitro coffee faucet with a restrictor plate is what creates the cascade. A cold brew keg dispenser runs from a keg you fill yourself; a cold brew coffee machine commercial sites plumb in brews and chills in one box.
A commercial iced coffee dispenser holds brewed coffee cold and stirred without the gas — cheaper, and right where the menu says iced rather than nitro.
