Gongju, a city in South Korea, has introduced a new product, 'Bam Yeoyu', a chestnut milk made by adding chestnuts to locally produced milk. The product is now available in local food stores and online markets. The city hosts an annual contest to develop chestnut-based products and hopes that the new milk will stabilize chestnut production farms and boost the local economy. Gongju is home to 2,100 farms that produce 8,000 tons of chestnuts, which is 17% of the country's annual production.
