A vine planted today will be farmed for decades. That makes replanting the single most consequential decision a small winery takes — and the one where science offers the clearest, most practical help.
What soil analysis answers
Soil is not one question but several: how it holds water, how it warms through the season, what the roots can actually reach. Each of these shapes which variety and rootstock will thrive as conditions change.
- Water-holding capacity decides how a vineyard survives dry summers.
- Soil temperature regimes affect ripening as much as air temperature.
- Depth and structure determine whether roots can reach reserves in a heatwave.
Where ERA's research programme comes in
Soil and vineyard suitability is one of the four priority areas of ERA's research programme. The aim is simple: by the time a family estate has to replant, the analysis that informs that decision should be affordable and understandable — not a luxury reserved for large producers.
Findings from funded projects will be published on this platform as practical recommendations.
