Abstract: Provided herein are compositions and methods useful for producing thermophilic fermented dairy compositions, such as thermophilic fermented dairy products, having cream flavor. The compositions and methods provided herein include bacteria, e.g., Lacticaseibacillus rhamnosus, useful for decreasing acetaldehyde content and increasing diacetyl content in a thermophilic fermented dairy composition and producing a cream flavor. Thermophilic fermented dairy compositions, including stored thermophilic fermented dairy compositions, produced according to the methods described herein are provided. Also provided are methods of identifying bacteria useful for producing thermophilic fermented dairy compositions having cream flavor.
