Checking the production year, bottling date, and batch details of a bottle of Kweichow Moutai involves closely inspecting the specialized security labels, inkjet printing codes, and packaging markers found on the bottle. Authentic Moutai bottles feature a distinct multi-line inkjet laser code printed on the side of the red bottle cap or neck seal. This inkjet text typically consists of three distinct lines of data: the top line explicitly indicates the exact calendar date when the bottle was produced and left the factory (providing the precise manufacturing year), the middle line details the blending date, and the bottom line displays the unique factory batch serial number. Additionally, collectors and buyers examine the bottle's bottom glass factory symbols, label textures, and official anti-counterfeiting reactive markers to verify authenticity alongside the production year.
