Strained, or "Greek" yogurt as it is called in the U.S., is much thicker, creamier, and tangier, with a higher protein content, as the whey is strained out. To manufacture strained yogurt, Ulukaya needed a million-dollar commercial machine called a milk separator, which the American-style Kraft factory did not have. He found a used one in Wisconsin and negotiated to buy it for $50,000. On his trip to pick up the separator, the name "Chobani" – a variation on çoban, the Turkish word for shepherd – popped into his head.
