The vineyards are distributed around the cellar going from the Ebro rivers left shore to Cantabria hill range, close to the entrance of the Ebro river inside Rioja. This altitude gradient allow them to keep a steady production of good quality wines, no matter what the summer temperature is.
There are 500 Ha. of vineyards that their engineer monitors daily, utilising even satellites to do it. The strategy of Cesar, the engineer, is to prevent environmental hazards, so as to reduce the application of chemical treatments. Fertilisation is almost completely organic. Their chief wine-maker, Manu, takes the different batches of grapes to different tanks so they can produce very dissimilar wines. Manu comes from a well-known family of oenologists in Haro. Of course, the quality-control system includes a Hazard Analysis and Control of Critical Points HACCP and it's got the BRC and the IFS certification.
