Quick answer
Brewery walk-ins hold kegs and cases cold, usually 34–38°F, and often feed draft lines to the bar. Winery cold rooms run warmer and care more about steady temperature and humidity. Both put heavy, dense loads in the box and both suffer when warm product goes in. Service covers the walk-in system and often the draft or glycol equipment tied to it.
Typical setpoints
| Use | Typical range | Notes |
|---|---|---|
| Keg and case cooler (beer) | 34–38°F | Draft pours best cold and steady |
| Direct-draw keg room behind a bar | 34–38°F | Short lines; the walk-in temperature is the beer temperature |
| Wine storage | Around 55°F, steady | Humidity and stability matter more than cold |
| Grape or juice cold storage | Depends on the process | Large heat loads at harvest |
Brewery and taproom problems
- Warm kegs loaded straight from delivery overload the system; give them time or pre-chill.
- Foamy beer that is really a walk-in temperature problem. See the beer and draft guide.
- Glycol power pack issues on long-draw systems.
- Condensing units in hot brewhouses running long.
- Floors and doors damaged by keg handling.
Winery cold rooms
Wine storage cares about stability. Large swings during defrost or door openings stress product. Systems for wine rooms are often sized for low temperature difference and steady humidity. Harvest brings heavy loads and long hours; book maintenance before crush, not during it.
Designing or upgrading a brewery walk-in
- Size for pull-down of warm kegs, not just holding. See sizing.
- Use heavy-duty floors or floorless boxes on a sealed slab for keg carts.
- Plan draft line routing and insulation with the bar layout.
- Consider remote condensing units to keep heat out of the taproom. See self-contained vs remote.
Brands
U.S. Cooler's Brew Cave and many standard walk-ins serve breweries. See U.S. Cooler and brands we service. Small producers sometimes start with a CoolBot room and outgrow it.

Vietnamese-speaking staff are available.
Pulling down a warm keg delivery
A full keg holds roughly 15.5 gallons of beer, and a delivery of a dozen kegs at room temperature is a large heat load. A system sized only to hold temperature may take a long time to pull them down, and the beer already in the box warms meanwhile. Options include staggering deliveries, cold-chain delivery, a system sized for pull-down, and keeping the walk-in door closed while new kegs chill. Check product temperature, not just air, before tapping.
Draft lines and the walk-in
| System | How beer is kept cold to the tap | Walk-in impact |
|---|---|---|
| Direct draw | Short lines from a keg box or walk-in wall straight to the faucet | The walk-in temperature is the beer temperature |
| Air-cooled long draw | Cold air blown through an insulated duct alongside the lines | Adds load to the walk-in; duct fans must work |
| Glycol long draw | A separate glycol chiller pumps coolant along the lines in a trunk | Walk-in holds kegs; glycol keeps lines cold |
Foamy beer on long-draw systems is often a line temperature problem, not a walk-in problem. Check the walk-in first, then the glycol or air system. See the beer and draft guide.
Floors and doors in keg rooms
Kegs are heavy and get rolled, dropped and dragged. Walk-in floors take impact damage, and doors and frames get hit by hand trucks. Protect thresholds with ramps, add bumper rails, and inspect floor panels for cracks. A damaged floor skin lets water into the foam; a damaged door frame stops the door sealing. See panels and insulation.
Owner checks
- Check keg temperature with a probe, not just the display.
- Check the door closes and seals.
- Check evaporator fans and look for ice.
- Check the condensing unit is running with a clean coil.
- For long-draw systems, check glycol or air system operation.
When to call a technician
Call when keg temperature climbs or draft beer starts foaming after a busy day; often the walk-in cannot keep up with the load.
Open 7 days, 8 AM to 5 PM, with emergency service until 9 PM. CA Lic. #776244.
Frequently asked questions
What temperature should a beer walk-in be?
Usually 34–38°F for kegs and cases.
Why is my draft beer foamy?
Warm kegs or lines are a common cause; pressure and line issues are others. Check the walk-in temperature first.
Can I put warm kegs in my walk-in?
Yes, but a big delivery of warm kegs can overload the system. Stagger loading or size the system for it.
What temperature is good for wine storage?
Around 55°F with steady conditions is common.
Do you service glycol draft systems?
Yes, the refrigeration side of glycol power packs. See the beer and draft guide.
How long does it take to chill a warm keg?
It depends on the walk-in system and how many kegs arrive at once; large deliveries can take many hours. Check product temperature before tapping.
What humidity is good for wine storage?
Moderate, steady humidity helps keep corks from drying; follow your winemaker's guidance for your product.
Do brewery walk-ins need special floors?
Heavy keg traffic damages standard floors. Reinforced floors, floorless boxes on sealed slabs, ramps and bumpers help.
Can a walk-in hold both kegs and cases?
Yes, at the same 34–38°F, with shelving and floor space planned for each.
