 NōKA went out of business in 2011.In December 2006, the blog DallasFood.org published a ten-part series on the company's chocolate products that detailed the company's marketing claims and noted its refusal, unlike many other similar firms, to reveal the source of its couverture (the chocolate from which finished confections are made).It presented research on available couvertures that matched NoKA's descriptions of its product and concluded that NōKA sold an essentially unaltered version of couvertures produced by the French company Bonnat Chocolates while charging more than ten times the price asked by Bonnat.
