Abstract

The interest aroused by consumers stimulated the development of an experimental project to produce a seasoning named “Agresto” in the specific area of Amiata Mountain with the aim of affirming the territorial specificities of a natural product derived from unripe grapes obtained from local grapevine varieties to enhance their use in gastronomy. With this project, we intended to adopt several strategies in the vineyard and in processing in order to obtain a final product from grapes cultivated by “organic farming” having sensory characteristics suitable for various types of dish combinations. For this purpose were chosen local varieties grown in the ampelographic collection located in Cinigiano (Gr) and the hybrid ‘Isabella’ from which were obtained three experimental Agresto. In several years (from 2010 to 2014) was also produced from ‘Sangiovese’ the “Traditional Agresto” according to an ancient recipe. Tue variety ‘Isabella’ is grown sporadically without pesticide treatments while the other varieties were cultivated according to the organic farming method. Moreover the Agresto is produced without alcoholic fermentation, so as the final product is free from methyl alcohol. Tue goal is to get to the production of a unique and genuine seasoning through natural methods and without preservatives. Tue main composition of different Agresto produced was determined as well as antioxidant activity and microbial analysis. Interesting sensory profiles were obtained using a parametric sheet specially adapted to this type of product. Tue traditional Agresto currently marketed in very modest amounts remains a niche product particularly required by Tuscany kitchen. It is believed that its use will expand providing more opportunities for the productive sector.
