Gaia & Rey is a white wine produced from Chardonnay grapes sourced from two vineyards in Barbaresco and Barolo regions. One vineyard was planted in 1979 in Treiso, while the other, established in 1989 in Serralunga d'Alba, adds acidity and structure. The 3.6-hectare area focuses solely on Chardonnay, with poor soils limiting vine vigor. Higher planting density reduces yields to 30 hl/ha.
