In some beer bars and brewpubs, you might have seen a bartender flip a glass upside down and press it down on a water sprayer, just before dispensing beer into it. This isn’t just for show, and it’s not a trendy gimmick. It actually serves many purposes.
Quickly blasting the inside of a beer glass with water conditions the glass and improves the pour. Benefits include:
- It removes particles that washing may have left behind.
- It removes detergent residue, no-rinse sanitizer or other cleaning agents that may be invisibly residing in the glass.
- It rinses away dust in glasses that have been on a shelf for a while.
- It reduces foaming issues because the water “softens” the glass, making it have less friction.
- It cools the glass slightly, so it won’t warm up the beer beyond its serving temperature.

He also says that it helps to cool down glasses that have just exited the glass washer, especially during busy times when glasses are needed as soon as they exit the washer. “We wash our glasses with a high-temperature glass washer, which allows us to use less detergents,” he says, “but the glasses need to be cooled
