On July 21, 1969, history was forever changed when American astronauts Neil Armstrong and Edwin "Buzz" Aldrin became the first people to walk on the Moon’s surface. Armstrong’s famous quote, “That's one small step for man, one giant leap for mankind” also describes the “leap” dairy processors are making when manufacturing cheese, milk, and fermented dairy products like kefir, yogurt, and cottage cheese. Since ancient times, cultures and enzymes have evolved, leading to a longer shelf life, improved taste and texture, and a cleaner label for dairy.
