Nagy-Somló covers vineyards situated on the three volcanic hills of Ság, Kis-Somló, and of course Somló which frequently overshadows the appellation with its own smaller, more specific production rules. This is a white wine growing area, particularly Furmint, Juhfark, Harslevelu and Chardonnay.
Kreinbacher is one of the largest estates on the Somló hill, although with less than fifty hectares under vine, the emphasis is still on quality rather than quantity.
