Portugal has become a popular tourist destination in the recent years, encouraging the development of wine tourism. With increased demand and greater competition among wineries, managers must enhance wine tourism experiences to attract high-value customers in order to make wine tourism profitable and sustainable. One option is to have an appropriate set of standards to implement best practices in service, hospitality and overall experience. This research paper focuses on the development of a knowledge tool, in the form of a best practice manual. With the support of ViniPortugal, an inter-professional organization dedicated to promoting Portuguese wines, 63 wineries were selected to participate in this project, of which 47 confirmed their participation and provided the basis for the project findings. This paper will show the development behind a comprehensive best practice manual, based on literary theory, research, and real life evidence in wine tourism experiences in Portugal. The framework used for the best practice manual was an adaptation of the Knowledge-To-Action framework [1], which is divided into two sections, Knowledge Creation and Action Cycle. The project methodology is based on the Knowledge Creation format as follows: knowledge inquiry, knowledge synthesis and finally knowledge tool. By accumulating knowledge from different sources, the finished manual will be a powerful tool that provides management with practices, standards, and protocols in all areas of the wine tourism offer. The application, limitations and future use of the best practice manual are also discussed.

Phenolic compounds are important constituents of red wine involved in its sensory properties. Although wine tannins can come from microbial and oak sources, the main sources of polyphenol remains grape skins and seeds. In order to better understand the grape seed and skin tannins contribution to the final wine tannins content, an original approach of winemaking has been set up. Our protocol explains a simple method to determine the percentage of skin and seed tannins extracted in wine all along the winemaking. The advantages of this method are presented below:•This method allows us to describe tannins extraction kinetics in wine according to the berry part (skins and seeds).•Additionally, our protocol allows to specifically determine the percentage of tannins extraction according to the winemaking stages (alcoholic fermentation and post-fermentative maceration) and the berry part (skins and seeds).•To sum up, this method serves to enhance the comprehension of tannins extraction process in wine according to the berry part., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence work reported in this paper., (© 2020 The Authors.)
