Product Development Research Laboratory At the Product Development Research Laboratory at Fujisawa in Kanagawa, we extract the potential of fruits such as grapes in areas such as deliciousness and health functions, and conduct research and development into wines that enhance the enjoyment of the customer's dinner table and products that contribute to healthy lifestyles.

Grape quality is influenced by the local climate. Mercian is developing manufacturing technologies designed to bring out the characteristic aroma and hidden flavor components of every variety. These technologies are utilized in products such as Château Mercian Koshu Kiiroka and Château Mercian Koshu Gris de Gris.

We also develop products designed to meet customer demands for safety and security, such as wines made from grapes with a high content of components such as resveratrol and GABA and wines with antioxidant additives that have been carefully selected so as not to compromise flavor.

In the future we will continue to aim for research and development of ingredients and manufacturing technologies for the purpose of providing products that enable as many people as possible to develop an affinity for wine.
