A glass of cold beer with foamy head and sweet fizz guarantees a pleasant experience in the summer. As you may have realized that the major gas component in the bubble is the same one warming our planet, it would be natural to ask how many CO2 bubbles are released during our toast and how much beer bubbles contribute to the global CO2 footprint. Answers to these questions require an understanding of thermodynamics and kinetics of bubble nucleation and growth, provided by a recent report, and a grain-to-glass life-cycle-analysis.
