![]() ![]() Venus’ atmosphere consists of roughly 96 – 97% carbon dioxide. If the Earth’s entire atmosphere consisted of carbon dioxide our planet’s habitat and atmosphere would closely mimic that of the planet Venus. You can read more about how gas is used in pubs and brewing on our blog Carbon Dioxide or Nitrogen: Which Do I Need?Ĭarbon dioxide is known as a greenhouse gas and this means that it can ‘trap’ and retain heat. This is an important part of the taste of some drinks and counterbalances the sweetness in some. When CO 2 is used to create such beverages, sometimes it can leave behind the acidic or sour taste that is experienced if one inhales the gas in high concentrations (this is not recommended). Dry ice is typically used because, compared to water, it doesn’t affect the sugar concentration of the grapes themselves. Dry ice is condensed carbon dioxide and it is used to cool down bunches of grapes to prevent spontaneous fermentation. In wine making, a different type of carbon dioxide is used – dry ice. ![]() CO 2 is also colourless, but pure is heavier than air so if you had a leak from a CO 2 gas bottle, the gas would rest at floor level if it is undisturbed.Ĭarbon dioxide is used to produce carbonated soft drinks and sparkling water, such as Coca-Cola. As beer gas, carbon dioxide is typically used to transfer beer from kegs to dispensing taps via pressurised carbon dioxide. This is because it is at such a low concentration that we are accustomed to it but if you were to increase the amount of CO 2 available in the air, you would notice a sharp acidic smell and taste. The CO 2 in our atmosphere is odourless and tasteless. Below, we’ve summarised some of the most interesting and important facts about CO 2. Carbon dioxide is vital to our planet, from the air we breathe to the beer and construction industry, carbon dioxide is used in many wondrous ways. ![]()
