“Monte da Casteleja” – Our Story


The name “CASTELEJA” was given by an archaeologist who discovered, on this land, the ruins of a small castle dating back to the roman period. Archaeologists believe that the ancestral city of Lagos, called “Lacobriga”, was born around this valley, with sea coming much further inland, very close to our property.

“MONTE” is a typical Portuguese farm with a house on top of a small hill and its surrounding lands.

Guillaume’s grandfather, born in Sagres, a man with a high reputation in the Lagos fishing industry, bought this farm in 1952.

His french father first introduced him to the magic of wine, showing Guillaume how to carefully serve wine and teaching him the major differences in wine styles. Later he realized the great potential of Portuguese wines and soon became passionate to discover the richness and complexity of the world of wine during his travels and studies.

Guillaume inherited the land, long since abandoned, from his Portuguese grandfather and began revitalizing the property with the intention of making his own organic wines. He planted the first grapes in 2000 and in 2004 Monte da Casteleja produced its first wine.

Single Estate Vineyards

We want to recreate the concept of “vin du producteur”, using the combination of new technologies and ancestral art, like feet treading, maceration with stems, ageing in wood vats.

One of the most important times of the Monte da Casteleja is the grape harvest. It is the culmination of a year´s work, taking place in several days and creating wines for years to come. Despite the long days of intense work, concentration, and quick decision making, the harvest is accompanied by good human energy, entertainment, and festivity.

Since its inception in 1998, which wished to do the harvest “old-fashioned way” with the manual labor of selection and cutting of the grapes, transport to the winery in boxes of 15 kg, followed by steps on mill the best grapes at the end of day, as is still done in the best vineyards of the Douro.

There are long days loaded with songs and emotions that fill the hearts of those who participate.

And so, the harvest of Casteleja already beginning to get known, more and more poeple are interested in spending a day in the field, under a blazing August sun, between loaded strains and willful people, and that makes our wine very rich and powerful from all the synergies.

“terroir” and Algarve’s Viticulture

"terroir" and Algarve's Viticulture

The grape varieties, soil, climate and the sculptural work of man.

The “terroir” is the combination of these main features able to give shape and identity to a wine.

The Monte da Casteleja soil is unique in the area, good for vine growing, medium depth with a high percentage of clay and lime.

Inside, water is strongly kept and slowly released to the roots during the summer, when the plants need it more.

We believe that we have a special “terroir” here at Monte da Casteleja
