Look up, for example, why top Napa vineyards go for low yields. It's also basic chemistry. There is a finite number of nutrients in the soil, and the plant can make a finite amount of such things out of these nutrients (like phenols in the grape skins and... er.. this is not my subject, but I can look it up again myself should I have to).
- uvdiv 14y agoLook up, for example, why top Napa vineyards go for low yields. I tried and failed (wikipedia) -- can you point me to something informative? I don't know what I'm looking for. There is a finite number of nutrients in the soil, and the plant can make a finite amount of such things out of these nutrients (like phenols in the grape skins and... er.. this is not my subject, but I can look it up again myself should I have to). In general they're not finite. Phenols are just C,H,O -- they're made from water and CO2. All of these compounds, as far as I can tell: https://en.wikipedia.org/wiki/Phenolic_content_in_wine https://en.wikipedia.org/wiki/Phenolic_content_in_wine I haven't found anything that says that, for example, soil nutrients correlate with phenol concentrations in vines (for example). It's not obvious.
