Troubleshooting - Gas Supply: Why Mixed Gas

Why Mixed Gas?

Let's hear a story about pot roast. Generations of women in a family had always prepared pot roast the same way: cutting the ends off the roast. The youngest daughter asked why, and after a chain of weird conversations, the answer was: The pot roast didn’t fit in the super small oven the great-great-grandmother had, so she chopped the ends off. If it ain’t broke, don’t fix it. But sometimes, something we are used to doing or experiencing needs another viewpoint for improvement.

People are used to wasting beer. Bartenders open the tap and stick the glass under the faucet. Owners think the 2 gallons of beer that gets dumped from the bucket at the end of the night is normal. One of our first customers was a college bar with a direct draw and 60+ beers on tap. He told us that the blender saved him over $2,000/month in wasted beer compared to using 100% CO2.

Just because we’ve done it this way for generations, or because everyone else does it that way, doesn’t mean that it is the only way to do it. The cost of the correct mixed gas can save you the installation cost several times a year and improve your sales.

Another customer upgraded their gas supply without telling any staff and found a 30% increase in sales immediately. The initial beer ordered with dinner was good, so one good beer deserves another. Just because we don’t think it’s broken doesn’t mean we can’t fix it.

If you’re seeing these foaming issues and would like some guidance, call us or your draught system technician. Maybe your draught gas supply would benefit from mixed gas.
