The invention belongs to a technical field, and particularly relates to a carbon coffee yoghourt and a production process. The carbon coffee yoghourt is prepared from the following components in parts by weight: 83 to 88 parts of raw milk, 12.0 to 13.0 parts of edible sugar, 0.3 to 0.5 part of an emulsion stabilizer, 0.2 to 0.5 part of concentrated whey protein, 0.2 to 0.5 part of caramel syrup, 0.1 to 0.3 part of ground coffee, 0.5 to 1.5 parts of single cream, leavening agent Streptococcus thermophilus AibiS4.02T inoculating 25 to 50 EA/T, and leavening agent YO-MIX187 inoculating 30 to 60 DCU/T. The edible sugar is muscovado and monosaccharide, the quantity of the muscovado is 8.5 to 10.0 parts, and the quantity of the monosaccharide is 2.5 to 4.5 parts. The carbon coffee yoghourt solves the technical problems that the fermentation of high sorbose fermentation is difficult and the fermentation flavor and structural state are extremely poor after long-time high-temperature browning of milk, the empyreumatique flavor and fermentation flavor of the product are good, the product also has unique flavor of coffee and natural butter flavor of single cream, the structural state is uniform, fine and smooth, the fermentation time is relatively short, the quality is high, and the carbon coffee yoghourt is popular for consumers.
