New York-based siggi’s, maker of Icelandic-style yogurt, introduced three flavors of single-serve, whole-milk, drinkable yogurts: vanilla, strawberry and blueberry.

Consumers are guzzling the drinkable cultured dairy options — sales for refrigerated kefir products and shelf-stable yogurt drinks are on the rise. Sales for sour cream are also up. Meanwhile, sales for regular yogurt and cream cheese have dropped.

While yogurt sales increased a bit; those of other cultured dairy products, like yogurt drinks, kefir and cottage cheese, are seeing greater sales growth.

Karoun Dairies, San Fernando, Calif., launched Blue Isle Mediterranean yogurt drinks in four flavors: plain, strawberry, blueberry and pomegranate.
