Don Rafael López de Heredia acquired the Tondonia vineyard from a group of clergy in 1913. Situated on the right bank of the river Ebro, in Rioja Alta, it stretches over 247 acres; the soil is alluvial clay with a high proportion of limestone. There are 4 varieties of red grapes planted in this vineyard—Tempranillo, Mazuelo, Graciano and Garnacho—as well as a few acres of white grapes (Viura and Malvasia) planted in the whitest soils, from which R. López de Heredia makes their Tondonia Blanco.  

Tondonia represents the bulk of their production.
