Exploring Mesophilic Starter Cultures: A Comprehensive Guide to Culturing Milk

Mesophilic starter cultures are a versatile, accessible way to create a wide variety of cultured dairy products, providing unique flavors, textures, and nutrients that add depth to culinary dishes. Unlike thermophilic cultures that require high temperatures, mesophilic cultures thrive at moderate, room temperatures, making them simple to use for home and artisan production of dairy. In this article, we’ll dive into the different varieties of mesophilic starter cultures, their origins, uses, and ideal recipes, as well as how to feed and maintain these starters for the best results.
