Organic producers in General Toshevo, Bulgaria have successfully grown Ethiopian teff, a gluten-free grain that is gaining global popularity for its healing properties. The grain, which is added to the cereals already grown by the producers, thrives in the region's conditions and is resistant to drought, diseases, and soil pollution. It is ground in a stone mill for use in both kvass and yeast. Ethiopian teff is the most common cereal crop in Ethiopia and plays a key role in the country's economy.
