A pony keg is a popular choice for small gatherings, parties, and home entertainment. If you’re considering using a pony keg for your next event, you may have questions about its size, capacity, types, usage, and cost. This guide will cover everything you need to know to make an informed decision about using a pony keg.
What is a Pony Keg?

- Perfect size for small gatherings (ideal for 10-30 guests)
- Easier to transport and store compared to full-size kegs
- Lower cost compared to larger kegs
- Less beer waste if you don’t need a full keg
