Chinese coffee chain Luckin Coffee unveiled a much-discussed new product Monday in cooperation with spirits maker Kweichow Moutai: This latte macchiato contains a shot of high-proof millet-wheat liquor – Moutai. The alcohol content is said to be less than 0.5 percent, according to the supplier. Offered for 38 yuan, the drink will be half-price at launch. Kweichow Moutai already launched an alcohol-infused ice cream last year.
