FUN FACTS ABOUT CARBON DIOXIDE

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. Below, we’ve summarised some of the most interesting and important facts about CO2. What Does CO2 Taste Like? The CO2 in our atmosphere is odourless and tasteless. 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 CO2 available in the air, you would notice a sharp acidic smell and taste. CO2 is also colourless, but pure is heavier than air so if you had a leak from a CO2 gas bottle, the gas would rest at floor level if it is undisturbed. It’s Used to Make Tasty Beverages Carbon 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. In wine making, a different type of carbon dioxide is used – dry ice. Dry ice is condensed carbon dioxide and it is used to cool down bunches of grapes to prevent spontaneous fermentation. Dry ice is typically used because, compared to water, it doesn’t affect the sugar concentration of the grapes themselves. When CO2 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). This is an important part of the taste of some drinks and counterbalances the sweetness in some.
