The single use gas cylinders (74gr CO2 and 18gr Nitrogen) offer the most portability with the QuikTap Tabletop Dispenser. Our bulk gas option offers a less expensive gas dispense cost and is ideal for long term placement on the bar or for larger pouring events where space is not limited. The best part is our QuikTap lineup of dispensers are modular and can be adapted for both single use gas cylinders and bulk gas.
