Chateau Mercian Koshu Amicus 2025 and Chateau Mercian Japanese Sparkling Koshu Amicus Traditional Method 2024 to Be Newly Released on July 14 (Tuesday)

Mercian Corporation (President Masami Otsuka, hereinafter 'Mercian') and Viña Concha y Toro (President Eduardo Guilisasti, hereinafter 'Concha y Toro') will launch nationwide on July 14 (Tuesday) the fourth installment of their collaborative wine project, the 'Pacific Link Project': the 'Chateau Mercian Koshu Amicus 2025' and the 'Chateau Mercian Japanese Sparkling Koshu Amicus Traditional Method 2024'.

Last year’s third installment, the 'Chateau Mercian Koshu Amicus 2024', marked the beginning of new vineyard-level initiatives, including joint cultivation discussions and guidance with Concha y Toro. Focusing on the contemporary Japanese food and beverage trend of 'umami and aftertaste', the wine received acclaim for its complexity and depth, earning a gold award in the Koshu category at the Japan Wine Competition 2025.

Building on this success, this year the companies are exploring new possibilities of Japan’s indigenous 'Koshu' grape variety by launching not only the 'Chateau Mercian Koshu Amicus 2025' but also the new 'Chateau Mercian Japanese Sparkling Koshu Amicus Traditional Method 2024'. This product features secondary fermentation in the bottle (Note 1), preserving the fresh, fruity character of Koshu while delivering a rich, rounded taste and a pleasant drinking experience.

Note 1: A winemaking method where fermented wine is bottled with added yeast and sugar, triggering a second fermentation inside the bottle—primarily used to create bubbles in sparkling wines.

The 'Pacific Link Project' involves winemakers from Chateau Mercian and Concha y Toro visiting each other’s wineries to jointly develop wines. Through this initiative, Japanese wines from Chateau Mercian and Chilean wines from Concha y Toro are alternately produced in each country. Under the four concepts of 'Innovative', 'Sustainability', 'Global', and 'Luxury', the project aims to promote the charm of Japanese wine internationally and further invigorate the wine market by leveraging the expertise of both nations.

■ The Four Concepts of the Pacific Link Project

'Innovative'

- Winemakers from Japan and Chile collaborate with shared vision and passion. The annual winemaking cycle occurs twice—autumn in Japan and spring in Chile—due to differing climates, broadening expertise and introducing diversity into winemaking.

- Ongoing collaboration fosters annual innovation, continuously delivering new surprises and感动 to customers.

'Sustainable'

- Both Mercian and Concha y Toro aim to evolve their sustainable winemaking practices together.

- To offset greenhouse gas emissions (Note 2) generated from wine production and transportation, tree planting will be conducted in Chile to achieve carbon neutrality. (First planting carried out on March 6, 2024.)

Note 2: Calculation of greenhouse gas emissions from wine manufacturing and transportation.

'Global'

- Leveraging Concha y Toro’s global market experience, winemakers from both companies share their philosophies and co-create wines aiming for world-class excellence.

'Luxury'

- Targeted marketing campaigns are designed based on research into affluent consumers in Japan and Asia, aiming to expand into new consumer segments domestically and internationally.

- By uniting two leading wineries from Japan and Chile, the project challenges conventional winemaking to achieve premium positioning.

Mercian continues to propose new ways to enjoy wine, guided by its corporate purpose: 'Transforming nature’s blessings into happiness.' Together with nature-positive initiatives, the company aims to enrich human connections through the joy of wine.
