Kalttaisina
Kalttaisina is a term that refers to a specific type of cold brew coffee, originating from Finland. The name "kalttaisina" is derived from the Finnish words "kaltta," meaning cold, and "sinä," meaning you, which translates to "cold you." This unique brewing method involves steeping coffee grounds in cold or room temperature water for an extended period, typically 12 to 24 hours. The result is a smooth, less acidic coffee with a lower caffeine content compared to traditional hot brew methods. Kalttaisina is often served over ice and can be enjoyed as a refreshing beverage, particularly during warmer months. The process of making kalttaisina is simple and requires minimal equipment, making it an accessible and popular choice for coffee enthusiasts. The drink's popularity has spread beyond Finland, with variations and adaptations appearing in other countries.
