Grapes and growing conditions

What is planted

The source lists Riesling as planted here. A linked wine may use one of these grapes or a blend.

Soil and vine spacing

Recorded soil: Blackish-grey slate with volcanic elements; highly mineral. Geology: Slate and volcanic material.

The geological description alone is not enough to infer drainage, water storage or measured soil density.

A soil name is not a bulk-density measurement. BottlePicker only shows soil bulk density where a laboratory or modelled value exists. Texture interpretation follows USDA NRCS soil-water guidance.

Seasonal heat

Riesling: Cool-climate example; typically 1,800–2,500 growing degree days on the °F scale, equivalent to about 1,000–1,390 °C-days accumulated above a 10°C base.

Heat bands use Oregon State University Extension. The OIV climate method treats growing-season temperature as accumulated heat above 10°C, not a fixed daily target.

Site conditions

Aspect: Steep south-facing slope.
