Commercial Beer Glass Frosters: A Buying Guide
Beer glass frosters chill mugs and pint glasses well below refrigerator temperature, keeping draft and bottled beer colder for longer once poured — a small detail that matters a lot to beer-focused bars and restaurants. Choosing the right froster depends on your glass volume and bar layout.
Countertop vs Underbar Frosters
Countertop frosters sit above the bar for quick access and visibility, doubling as a merchandising element. Underbar models integrate into existing underbar equipment runs, saving valuable counter space in tighter bar layouts.
Capacity Sizing
Glass frosters are sized by how many mugs or pints they can hold frosted at once, generally ranging from a couple dozen up to several dozen. Match capacity to your peak-hour beer volume to avoid running out of frosted glassware during a rush.
- Small capacity: lower-volume bars, restaurants
- Large capacity: high-volume sports bars, breweries
Temperature Range
Look for frosters capable of reaching temperatures well below standard refrigeration (often near or below freezing) to achieve the frost effect on glass surfaces — a standard reach-in cooler won’t produce the same result.
Glass Shape Compatibility
Confirm the froster’s shelving and interior dimensions accommodate your specific glass shapes, since oversized mugs or specialty pint shapes may not fit standard shelving spacing.
Placement for Bartender Workflow
Position the froster within easy reach of the tap system and pour station so bartenders aren’t taking extra steps mid-rush to grab a frosted glass.

Frequently Asked Questions
How cold do beer glass frosters get?
Most reach temperatures well below standard refrigeration, often near or below freezing, to produce the visible frost effect on glass surfaces.
How many glasses should a froster hold for a busy bar?
This depends on beer volume — high-volume sports bars and breweries typically need larger capacity frosters than a lower-volume restaurant bar.
Do I need a countertop or underbar froster?
Countertop frosters offer visibility and double as merchandising, while underbar models save counter space in tighter bar layouts — the right choice depends on your available footprint.
Will a standard cooler frost glasses the same way?
No — standard refrigeration doesn’t reach the low temperatures needed for the frost effect, which is why dedicated glass frosters exist as a separate equipment category.
