Biondi Santi was always a staunch defender of a 100% Sangiovese Brunello di Montalcino, even at times when his wines were considered old-fashioned and out of date.
Red Solopaca wine is a blend of 45-60% Sangiovese, 10-20% Aglianico, 20-25% Piedirosso and/or Sciascinoso and up to 10% of other local red grape varieties permitted to fill in the remainder of the blend.
In the Pomino DOC based around the Rufina sub-district of the Chianti zone, Abrusco is permitted along with other local red grape varieties to make up to 15% of the blend along with Sangiovese (60-75), Canaiolo, Cabernet Sauvignon, Cabernet franc (collectively 15-25%) and Merlot (10-20%).
Another vineyard untouched by the blight is the Lisini estate in Montalcino: a half-hectare vineyard of Sangiovese, with vines dating back to the mid-1800s, which inexplicably never succumbed to phylloxera.
