“…The remaining three individuals have strontium isotope values higher (Or_07 and Or_12) or lower (Or_11) than the predicted local range, although still within the estimated values for the immediate to broader hinterland (5-50 km). Nevertheless, 87 Sr/ 86 Sr values between 0.7090-0.7105 are consistent with volcanic geologies in central Italy (Holm and Munksgaard, 1982, Palombo et al, 2005, Pellegrini et al, 2008, Marchionni et al, 2013, Tescione et al, 2015 as well as the value (0.710216) of spring water bottled at Orvieto (Voerkelius et al, 2010). Strontium isotope ratios from individual Or_11 (less than 0.7087) fall below the 0.7092 value of modern seawater (McArthur et al, 2001).…”

“…The precise location of these localities requires further Sr baseline sampling of the area; however, related studies provide an indication of possible areas of 666 management. Two sheep (Or_07, Or_12) derived from an area with relatively high Pellegrini et al, 2008, Tescione et al, 2015 or regular ranging between a volcanic geology and area(s) with lower bioavailable 87 Sr/ 86 Sr values. Sheep Or_11 had an origin in an area 673 with low strontium isotope values (<0.7087) distinct from the previous zones.…”

Highlights-A multi-isotope pilot study offers a high-resolution investigation into sheep management in proto-historic Italy -Sheep exploitation at an Orientalising aristocratic residence (7th century BC) was consistent with management in the local hinterland -An Archaic Etruscan city (5th century BC) drew animals from a mosaic of iso-zones -Neither Etruscan site produced clear evidence for long-distance vertical transhumance 25

“…[30,31]. The winemaking process of red and white wines does not affect the 87 Sr/ 86 Sr ratio of wine, so this allows to link the Sr-isotopes of wine to those of the vineyard substratum [32,33].…”

“…Preliminary studies using Sr isotopes as possible fingerprint for deciphering the geographic provenance in high quality wines provided questionable results essentially due to the analytical uncertainty of 87 Sr/ 86 Sr measurements reported, which were usually larger than the Sr-isotopic variability shown by most of the rocks/soils on Earth (e.g., Horn et al, 1993;Vasconcelos, 2003, 2004;Vorster et al, 2010;Di Paola-Naranjo et al, 2011). In the last years the mass spectrometry analytic techniques were improved, allowing the researchers to perform Sr isotope measurements on samples of grape, must, wine, and soil with the same analytical precision of that obtained for geologic materials, thus enabling the comparison of the Sr radiogenic isotope composition in red wines to their own terroir of geographic provenance (e.g., Boari et al, 2008;Marchionni et al, 2013Marchionni et al, , 2016Tescione et al, 2015;Durante et al, 2016Durante et al, , 2018Vinciguerra et al, 2016;Braschi et al, 2018;Epova et al, 2019).…”

The measuring of 87 Sr/ 86 Sr in wine, grape, and bioavailable soil fraction samples with the same uncertainty of geological materials allows fully comparing the whole wineproduction chain with the peculiar geochemical isotope signature of any geographic area. Indeed, this signature is the same as the final product inherited by the soil bioavailable fraction and, in turn, by the geological substratum of the vineyard. On the other hand, the few data available in literature that referred to white wines cast doubts for the use of this geographic tracer due to the common use of geological derived additives, such as bentonite, in the white wine-making procedure, which may overprint the original geochemical signature of the vineyard substratum. To tackle this issue, we analyzed the Sr-isotope compositions of four white wines produced over a period of almost 10 years in a high-quality organic farm, located on the volcanic units of the Vulsini Volcanic District (southern Tuscany, Italy). The 87 Sr/ 86 Sr values of rock, soil, grape, grape juice, must, and wine were compared among them and further weighted against the isotope fingerprint of the bentonite and yeast employed during the winemaking process. The 87 Sr/ 86 Sr values from the entire white-wine production chain reveal that no variations are observed from the signature imprinted by the original geological substratum (rocks and soils), suggesting that no further contribution is given by the addition of bentonite and yeast to the white wine Sr-isotope values. On the other hand, intermediate 87 Sr/ 86 Sr compositions are found when grapes from different vineyards are used for making multi-cultivar wine blends. Indeed, the experimental data clearly show that the Sr isotope composition is maintained through the wine-making process for white as well as for red wines. Both grape and final wine preserved the isotope signature inherited from the labile fraction of the soil where the vines are farmed. Our data thus confirm, also for white wines, the robustness of the Sr-isotope tool in studies where it is important to define terroirs and geographic provenance.
