As a consequence, Tom Scott wasn’t able to see all or possibly even most of the Agroscope facility. But he was able to pry out of the food scientists why Swiss cheese has (or at least used to have) many holes inside. It’s not because of the traditional explanation: bubbles of carbon dioxide formed during the fermentation process.
