The original building was put up in 1840 by J & J Grant of the
legendary Grant dynasty who ran it pretty un-spectacularly until Seagram got hold of it and modernised it.Grants extended production in 1973 to 6 stills but the brand really expanded under Seagrams ownership in 1977 when they upped capacity to 10 stills.
Sadly this compromised the quality a bit. Since Seagram bought this classic Scottish distillery in 1977, it has become more successful, especially abroad.
