For the first time, the boron isotopic ratio is reported for Brazilian red wines. The boron concentration, B/B isotopic ratio and δB were determined in 89 red wines produced in Campanha Gaúcha, Serra Gaúcha (SG), and Vale dos Vinhedos (VV) in South Brazil and Vale do São Francisco (VSF) in Northeast Brazil. A broad boron concentration range, < 0.07 to 20.4 mg L, was observed, where a few values were above the maximum allowed concentration according to the International Code of Oenological Practices (14.0 mg L). The obtained B/B ratios were quite different from those observed in the literature. The ratios were quite similar among the Southern Brazilian wine producing areas, but a large difference was observed when compared with the Northeastern wines, allowing for the differentiation between these two important Brazilian wine regions. The results have also shown that is possible, based on the boron isotopic ratio, to differentiate the Brazilian red wines from Chilean, Italian and Portuguese red wine.
