Beer Mix 40 is another commonly used gas mixture for dispensing various types of beer, particularly draught beers. This blend consists of a 40/60% ratio of Carbon Dioxide and Nitrogen, which helps address wastage issues that can occur with slow moving bulk beers.
As with other beer mixes, the "as brewed" CO2 content in all beers plays a significant role in determining their taste and appearance. Beer Mix 40 ensures that the beer maintains its intended balance. The Carbon Dioxide component helps maintain the original CO2 volumes, while the Nitrogen part provides the necessary pressure for effective dispensing.
