A pony keg, also known as a quarter barrel, is a small keg that holds around 7.75 gallons or 29.34 liters of beer. Pony kegs are commonly used for parties, picnics, and other small gatherings where a full-size keg may be too large. But exactly how big is a pony keg?
The Dimensions of a Pony Keg
A standard pony keg stands 23.3 inches tall with a diameter of 16.12 inches. Laid on its side, a pony keg measures 23.25 inches long by 16.12 inches wide. In terms of volume, as mentioned above, a pony keg holds 7.75 gallons or 29.34 liters.
To visualize the size, a pony keg is about two-thirds the height of a full size keg and about half the volume. It’s small enough to be lifted and moved by one person but large enough to provide beer for a medium-sized gathering.
Weight When Full and Empty
When completely filled with beer, a pony keg weighs approximately 47 pounds (21 kg). When empty, the keg itself weighs around 15-20 pounds (6.8-9 kg). The weight varies slightly depending on the material the keg is made from – aluminum or stainless steel are common materials.
So a full keg is quite heavy, while an empty one is light enough for one person to carry around. Keep this in mind when stocking up for a party!
Amount of Beer in a Pony Keg
As noted, a standard pony keg holds 7.75 gallons or 29.34 liters of beer. Here is how much beer that equates to depending on cup size:
Cup Size | Amount |
---|---|
16 oz pint | 124 pints |
12 oz bottle/can | 165 bottles/cans |
10 oz glass | 195 glasses |
5 oz taster | 388 tasters |
As you can see, even though a pony keg is smaller than a full size keg, it still holds a considerable amount of beer – enough for a medium to large gathering, depending on serving sizes.
Comparing to Other Keg Sizes
To put the pony keg size in context, here’s how it compares to some other common keg sizes:
Keg Size | Total Volume |
---|---|
Pony Keg | 7.75 gallons |
Quarter Keg | 7.75 gallons |
Half Barrel | 15.5 gallons |
Full Keg/Barrel | 31 gallons |
So a pony keg contains half as much beer as a full-size keg. Quarter keg and pony keg are in fact the same size, just different names. As you move up to a half barrel and full barrel, the capacity significantly increases.
Advantages of a Pony Keg
There are a few key advantages to choosing a pony keg over a larger keg size:
More Manageable Size & Weight
At around 24 inches tall and less than 50 pounds when full, a pony keg is much easier to transport and maneuver compared to a large, heavy full size keg.
Right Amount for Smaller Parties
For gatherings of 25-50 people, a pony keg is a perfect amount of beer. You reduce the risk of having too much leftover.
Lower Cost
Obviously, a smaller amount of beer costs less than a large keg. Pony kegs are an affordable option.
Takes Up Less Room
A pony keg can easily fit in a refrigerator or cooler, great for keeping the beer chilled at home or transporting to a party.
Easy to Finish
With just over 120 pints of beer, a pony keg is a manageable amount that won’t go stale before it’s finished.
Where to Get a Pony Keg
Wondering where you can get your hands on a pony keg? Here are some options:
Liquor Stores
Many local liquor stores will stock and sell pony kegs. Call ahead to check availability. Prices can range from $65-$100 depending on brand.
Beer Distributors
Beer distributor warehouses are a great place to browse and buy kegs. Expect discounts for buying in bulk or choosing less popular brews.
Directly from a Brewery
Support local breweries by buying a pony keg directly from them. Ask what sizes they have and how far in advance you need to reserve one.
Online
Numerous online beer and liquor delivery services offer pony kegs. Shop variety packs or build your own custom order. Remember to account for shipping costs on heavier kegs.
Serving Beer from a Pony Keg
Once you secure a pony keg, here are some tips for serving beer from it:
Chill Properly Before Serving
Always chill a keg to around 38-42°F before tapping and serving. This prevents foaming issues. Store in a refrigerator or use a chilling sleeve/bucket.
Use CO2 for Best Taste
For ultimate beer taste, dispense from the keg using a CO2 system. This prevents oxygenation as the keg empties. Rent or buy a pony keg CO2 tapper.
Consider a Tub/Ice Bath
For outdoor gatherings, set the keg in a large tub filled with ice to keep cold. The drain allows removing melted ice water.
Clean Lines & Replace Couplers
Always sanitize beer lines and replace the keg coupler between kegs for best results. Dirty lines can ruin the taste.
Offer Different Tap Beverages
Consider offering 1-2 different beers on tap from multiple pony kegs. Or do a beer + wine combo. More variety for guests!
