Each year, International Beer Day is celebrated on the first Friday of August. As you may know, beer is produced using only four ingredients: water, hops, malt and yeast, through a process called fermentation.

Of course beer is harmful in excessive quantities, but don’t let that give you any misconceptions about fermented foods. Generally speaking, they play an important role in boosting gut health. There are many other alcohol-free alternatives too, if you’re looking for a fermented beverage. These include kombucha, a fermented tea which contains B vitamins and vitamin C, and kefir, which is a kind of fermented milk.

How do fermented foods interact with our bodies? How does fermentation actually work? How can I get started producing homemade fermented foods? In under 3 minutes, we answer your questions!
