The environment plays a huge role in growing fruit.

The subtleties of texture and flavor (and hence the finished wine) 
depend not only on variety and growing practices, 
but also (and critically) on environment.

Environment can be discussed on many scales:
    within the row of vines/trees/plants = 'microclimate'
    site conditions = 'terrior'
    regional environment
    global - especially with reference to climate and ecological drift.
