Mesoclimate is what happens in a region on a smaller scale. The mesoclimate has variables in altitude, soil types, and the distance from a river ~ where the fog will burn off further away from a river’s bank first, and evaporate to the river’s edge as it goes through the burning off process.

Microclimate is what exists within a few rows of a vineyard. It’s in the microclimate that vineyardists have the most control of managing for distinct flavors and aromas of wine grapes and the resulting wine. This is the reason why we’re continually reading about this particular climate over all the others.

As I walked with Dick Keenan at his Kick Ranch Vineyard, Dick explained that those winemakers who are buying his fruit are very row specific for what they’re purchasing, because they’ve been in on all the vineyard practices for those exact microclimate rows. The winemakers know the rows so well, and have had a hand in shaping the vines’ microclimates, that they’re not interested in anyone else’s vines, except as a curiosity once the wine’s been produced.

Canopy microclimate refers to the environment around the individual foliage of a vine. While a vineyard would have had early morning fog, as it burns off, cool moisture remains under the vine’s canopy. While it’s burning off above the vine bringing in warmer air, within the canopy system, it takes a bit longer for the fog to evaporate, and consequently keeps the grapes a bit cooler for an extended period of time.
