Multiple winemaking sites
In addition to Katsunuma, Kikyogahara Winery was established in 2018 and Mariko Winery in 2019. You cannot determine that all grapes come from Yamanashi simply by the producer name Château Mercian. Distinguish between wines and facilities for each region.
The Mariko vineyard began operation first.
The Mariko vineyard was established in 2003 and the winery in 2019. The vineyard, at about 650 m elevation on clay soil, is planted with Merlot, Chardonnay and others. Do not interpret the facility’s establishment year as the year the first vines were planted there.
Compare left and right sides of the river in Hokushin
Chardonnay in Hokushin is explained by separating the left and right banks of the Chikuma River. The left bank is clay soil at 330–360 meters altitude, and the right bank is gravel soil at 430–600 meters. Read this as a comparison not only of river sides, but also of altitude and soil type.

Château Mercian Source Interpretation: Vineyard and Winery Establishment
Check and compare the region, raw materials, and process from the materials, and explain what can be learned from the comparison.
Comparative tables are based on the source’s target year and the explanation at the time of verification. Descriptions without year specifications are not treated as specifications common to all harvest years or shipped portions.
| Comparison items | Source description/content | Subject to verify |
|---|---|---|
| Mariko 2003 | Vineyard establishment. | Not the year the winery was established |
| Mariko 2019 | Establishment of the winery | Differentiate the year planting began |
| Both banks of Hokushin | Chardonnay regions differing in elevation and soil | Not a comparison limited to only riverbank conditions. |

What does Mariko 2003 represent?
The Mariko vineyard was established in 2003 and the winery in 2019. The vineyard, at about 650 m elevation on clay soil, is planted with Merlot, Chardonnay and others. Do not interpret the facility’s establishment year as the year the first vines were planted there.
When was the Mariko Winery established?
The Mariko vineyard was established in 2003 and the winery in 2019. The vineyard, at about 650 m elevation on clay soil, is planted with Merlot, Chardonnay and others. Do not interpret the facility’s establishment year as the year the first vines were planted there.
What differences are indicated in the materials between the two banks of Hokushin?
Chardonnay in Hokushin is explained by separating the left and right banks of the Chikuma River. The left bank is clay soil at 330–360 meters altitude, and the right bank is gravel soil at 430–600 meters. Read this as a comparison not only of river sides, but also of altitude and soil type.
