For this, a 3.5 MHz transducer has been used by means of an immersion technique in pulse-echo mode. The tests were performed at various temperatures in the range 14\u201318 \u00b0C. The evaluation has been carried out studying, on the one hand, conventional analysis parameters (velocity and attenuation) and, on the other, less conventional parameters (frequency components). The experimental study comprised two stages. In the first, the feasibility of the study was checked by inspecting twelve samples belonging to six varieties of red and white wine. The results showed clearly higher ultrasonic propagation velocity values in the red wine samples. In the second, nine samples of different monovarietal wine varieties (Grenache, Tempranillo and Cabernet Sauvignon) were analyzed. The results show how ultrasonic velocity makes it possible to unequivocally classify the grape variety used in winemaking with the Cabernet Sauvignon variety having the highest values and the Grenache the lowest. In addition, the wines of the Tempranillo variety are those that present higher values of the attenuation coefficient, and those from the Grenache variety transmit higher frequency waves.<\/jats:p>","DOI":"10.3390\/s24134294","type":"journal-article","created":{"date-parts":[[2024,7,2]],"date-time":"2024-07-02T05:08:34Z","timestamp":1719896914000},"page":"4294","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Use of Non-Destructive Ultrasonic Techniques as Characterization Tools for Different Varieties of Wine"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9018-8083","authenticated-orcid":false,"given":"Jos\u00e9 \u00c1ngel","family":"Corbacho","sequence":"first","affiliation":[{"name":"Department of Applied Physics, IPROCAR Research Institute, Centro Universitario de M\u00e9rida, Universidad de Extremadura, Avda.
