To get the best pour possible you want to make sure your glass is free of dust, debris, and dish soap residue. The easiest way to do this is with a quick rinse of cold water right before pouring beer into the glass. This drip tray features a push-activated jet that can be hooked up to a pressurized keg or main water supply. To give your glass a quick spritz, simply press it down on the rinsing platform to activate the jet. The drip tray also has a pre-plumbed drain outlet to run to a nearby bucket or drain. For best results feed the jet clean, cold water at a pressure between 15 to 60 psi. If directly connecting to your main water supply, we recommend using an inline regulator to lower the water pressure as needed.
