In the context of the modern «economy of impressions» and the active development of domestic tourism in Russia, gastronomic tourism is becoming a key driver of regional development. However, many territories face the problem of low recognition and weak differentiation of their tourist products in the federal market. The purpose of this study is the theoretical justification and design of the visual component (design code) of the regional gastronomic brand, capable of accumulating the territory cultural code and ensuring its stable identification. The resort cluster of the Caucasian Mineral Waters (CMW) is considered as a key case. The methodological basis was a systematic approach, content analysis of existing gastronomic brands, a method of expert assessments and a detailed case stage. The author systematizes scientific approaches to the concept of «gastronomic brand» and analyzes existing brands in the region, including mineral waters and local gastronomic products. Based on the study of the cultural and historical heritage and traditions of Caucasian hospitality, the author suggests using a traditional pump mug and narzan ladle as the basic visual symbols of the CMW gastronomic brand. It is justified that the introduction of a single visual identity in navigation, the interiors of HoReCa establishments and digital communications forms a deep emotional connection with the audience. In addition, the article explores the role of public art and visual components in hotel branding on the example of Russian hotels, where the physical attributes of the environment act as a powerful tool for storytelling. It has been proven that a gastronomic brand visualization has a pronounced multiplier economic effect, stimulating the development of related industries and increasing conversion. The research results can be used by tourism authorities, destination marketers and representatives of the hospitality industry to develop comprehensive territorial marketing strategies and create competitive tourism products that can work effectively in a highly competitive domestic travel market.
