Kefir is not milk with a pedigree, but it is cultured and it's the lifeblood of Lifeway Foods. In addition to the yogurt-like dairy beverage called Kefir (sold under the Tuscan, Lassi, and BasicsPlus brands), the company's products include farmer and cream cheeses, Sweet Kiss (a sweetened cheese spread), and a vegetable-based seasoning called Golden Zesta. Its ProBugs offering, a flavored drink with live kefir cultures packaged in pouches, is aimed at children. A longtime staple in the dairy cases of health-food stores, Lifeway's products are available throughout the US, as well as internationally. The dairy products company has been expanding its products portfolio with additional children's items.
