A new Excel tool, SunMask, is proposed to assess the topographic sunpath in a vineyard. Hemispherical pictures are used to describe light microclimate within the canopy. Light profiles in 11 positions around and within the canopy are reported. Possible effects of row orientation on berry temperature/composition are discussed.
