Explore fermentation from Aceh to Papua

Indonesia's tropical climate makes it rich in fermentation. Almost every region has its own foods and drinks.

Foods

Indonesia has many fermented foods because its tropical climate supports the growth of microorganisms.

Drinks

Indonesia also has a tradition of fermented drinks, a cultural heritage passed down through generations.
