Sustainability

Sustainability score: 6/10

Mars Hosaka sources locally-grown grapes, employs integrated pest management, and uses water-saving irrigation with some natural treatments; moderate attention to lightweight packaging and energy management.

Mars Hosaka Winery demonstrates above-average sustainability via local sourcing, integrated vineyard management, and efforts to minimize water and energy use. However, lack of formal organic/biodynamic certification and standard packaging limit its score. The winery’s location in Japan reduces food miles for the local market but increases carbon impact for exports. Ongoing improvements and greater transparency around energy and packaging would further enhance sustainability.
