J.M. Goncalves Factory Portugal

The history behind J.M. Goncalves:

The art of the cooper began nearly 100 years ago with Abilio Goncalves, (The Father of the Company) who started the manufacturing of barrels for wine producers in the region of Tras -os- Montes in Portugal. 

 This hand crafted process was carried on by his son, the founder, Jose Maria Goncalves for almost 20 years. 

 The mid 60’s saw Jose leave Portugal and moved to France to work in a cooperage. Soon after this he started a small workshop in his Garage, working day and night with the help of his older children. 

 In 2001 Jose Maria had made a huge name for himself and the family business continued growing and a new factory was built in Cantara, the East Coast of Portugal.

Great lengths and research goes into the rigorous selection of the geographical & botanical origin as well as the type of grain. Only then is it possible to achieve a superior organoleptic characteristic of great wines. (i.e, characteristics that can be perceived by human senses: smell & taste). 

The cooperage selects its own wooden trunks which guarantees its origin. 

All of the Oak comes from ecological forests and is under a controlled slaughter. 

The process of identification and traceability is certified by Bureau Veritas. 

Based on this system you can track the entire production process, following the route from forest to the cellar.

Types of Oak:

European Oak - A selection of this timber begins in the beautiful forest of Allier (region of central France) and Voges (massif located in the Alsace-Lorraine region of France close to Germany), the best quality of Oak, (Quercus petrel or sessiliflora). This timber is characterised by a particular type of grain, (visible growth rings inside the trunk of a tree) thin. It is a privileged wood, delicate nature, with a “boise” very thin, which fully respects the fruit wine throughout their probationary period. 

 This type of Oak can also be found in other regions of Eastern Europe, particularly in Russia, Hungary and Romania. 

 American Oak - (Quercus alba) comes from Missouri, Ohio Pennsylvania and Minnesota forests, is selected from the best type of American white oak. 

The selected American oak reveals a rich and complex aromatic character.
