Oat milk is used as a substitute for dairy milk in custom coffee preparation[1][2][3] and in fermented dairy products, such as yogurt and kefir.[8][24][25] Baristas claim that oat milk needs less steam than cow milk, froths favorably, is tasteful, rich, and creamy like cow milk, and effectively balances the acidity of espresso coffee.[3][6][8][7][26] It has growing applications in coffee preparation at major coffee shops like Starbucks.[8] Like other non-dairy milks, oat milk may be used as a substitute for dairy milks when cooking or baking.[18]
