Data Notes and References

Notes

Farm Certifications: See the certifications page to learn more about the farm certifications Everyvine tracks. Soil Horizon: Bedrock value set to "-" is not available. Available water capacity units are cm/cm. Solar Radiation: Area Solar radiation has been calculated in watt hours per square meter (WH/m2) Topography: Topography values are averaged over the block area. Aspect is expressed in positive degrees from 0 to 359.9, measured clockwise from north. Growing Season: For use in various statistical averages, Everyvine defines the vineyard growing season as the period April 1st to October 31st.
