i. Biography
For oenology, laboratory discipline is not an accessory to cellar work; it is one of its controls. In the career of Graziana Grassini, Consultant Oenologist of Giusti Wine in Treviso, Italy since 2020, that line runs through analysis, Italian wine institutions, tasting commissions, and estate consultancy. The working principle is direct: wine is not to be manipulated, but revealed.
The Path
The technical base was built through an Analysis Laboratory specialized in the oenological sector, founded early in Graziana Grassini’s career, then extended through collaboration at Giacomo Tachis from 1994. The Title of Oenologist in 1994 fixed that scientific practice inside the recognized profession. Subsequent work moved through Sicily and Tuscany: project collaboration at Regional Institute of Wine and Oil of the Sicily Region (former IRVV) in Sicily, Italy; teaching at Faculty of Agriculture of the University of Pisa, Italy; and presidency of the DOC Wine Tasting Commission at Grosseto Chamber of Commerce in Grosseto, Italy. The current field of work includes Consultant Oenologist of wineries in Italy, member of the Scientific Committee of O.N.A.V. (National Organization of Wine Tasters) (since 2019), and Consultant Oenologist of Giusti Wine (since 2020).
The Work Today
Consultancy at Giusti Wine in Treviso, Italy, from 2020 to the present, places technical reading, tasting discipline, and cellar judgement inside a contemporary estate setting. In Graziana Grassini’s work there, the emphasis remains on revealing material rather than correcting it into anonymity. The official oenologist role at Tenuta San Guido in Bolgheri, Italy, sits within the same Italian consultancy practice, where cellar decisions are tied to site, variety, and continuity of house work. Institutional tasting work requires a different discipline from production: assessment must be communicable, repeatable, and useful to other tasters. Graziana Grassini’s 2019 appointment to the Scientific Committee of O.N.A.V, the National Organization of Wine Tasters, connects her technical and tasting practice to an organization devoted to wine assessment. Regional interpretation, as she has described it, starts with the varieties and the production method already present. Her stated goal is to work on Montepulciano and Trebbiano, and also to interpret the Metodo Classico that Nicola Di Sipio, one of the first in Abruzzo, decided to produce from the beginning.

In Their Words “My goal will be to work on the region’s iconic varieties, Montepulciano and Trebbiano, but also to interpret the Metodo Classico, which Nicola Di Sipio, one of the first in Abruzzo, decided to produce from the very beginning.” “My scientific approach to wine began when, as soon as I graduated as an industrial chemist, I started my Analysis Laboratory.”
Acclaim
The Title of Oenologist in 1994 marks the formal point where scientific training entered recognized oenological practice in Graziana Grassini’s career. The presidency of the DOC Wine Tasting Commission at the Grosseto Chamber of Commerce added a public standard-setting function in Maremma’s wider wine culture. The 2019 appointment to the Scientific Committee of O.N.A.V. Continued that line of recognition, placing her expertise inside a formal framework for Wine Tasters.
