This rock sees widespread use in America as a "gray granite". The name is pronounced "berry". This material comes from the Barre Granite (Barre Pluton) of Vermont. It's actually a granodiorite, derived from a calc-alkaline pluton formed by partial melting of Silurian-Devonian sedimentary rocks that had been folded & regionally metamorphosed during the Acadian Orogeny in eastern America.
