Part three of the presentation is titled “CO2 Supply Chain and Purity”, here are some salient points:

“Commercial CO2 is produced from a wide variety of sources… quality can vary by region… impurities may remain in the CO2 due to residual traces carried over from feedstock, or an inefficient or poorly maintained gas treatment system…”

“CO2 is… an ingredient in finished beer, a CO2 purification system ensures that the CO2 gas used… is free from impurities or contaminants that have a negative impact on the flavor, taste, or appearance of the final beverage.”
