Muga sources its fruit from five separate vineyards throughout Rioja. Each vineyard enjoys a unique microclimate, which provides a wide range of influences on grape production, from the soil, through Atlantic, Mediterranean and landlocked winds, to elevation and solar exposure. With tempranillo as the predominant varietal grown and used, Muga also uses garnacha, mazuelo (aka carignan) and graciano for the reds, the last of the three being blended in small portions with the tempranillo to produce the winery’s different Riojas. Viura (aka macabeu) and malvasia are used for the white and sparkling (cava) wines.
