Which grape variety is legally allowed to be blended with sangiovese to make a Chianti?
D. All of the above
While Chianti mostly consists of sangiovese, Tuscany’s most-planted grape variety, both red and white grapes are used in blending. A basic modern formula for Chianti can be anywhere from 70% to 100% sangiovese; no more than 10% canaiolo; and no more than 15% “other authorized reds” like cabernet sauvignon and merlot. The white grapes malvasia and trebbiano can still be used (although they rarely are) for up to 10% of the blend.
