=== Climate and mesoclimate ===

[[Climate]] defines the broad limits of [[viticulture]], determining whether a site can reliably ripen grapes. Within a given region, mesoclimatic variation related to elevation, [[slope]] orientation, proximity to water and air [[drainage]] can significantly affect [[growing season]] length, frost risk and heat accumulation.<ref>Gladstones, ''Viticulture and Environment'', ~~Winetitles~~, ~~1992~~, ISBN ~~978-1875130101~~.</ref>

South- or east-facing slopes are often preferred in cooler climates to maximise [[solar interception]], while warmer regions may prioritise sites with moderating influences to avoid excessive [[heat stress]].

=== Topography ===

[[Topography]] affects both microclimate and vineyard logistics. [[Slope]] angle influences cold air drainage and erosion risk, while elevation can moderate temperature extremes and diurnal range.<ref>Keller, ''The Science of Grapevines'', Academic Press, 2015, ISBN ~~978-0124199873~~.</ref>

ISBN 9780124199873.</ref>

Cold air drainage is particularly critical in frost-prone regions, where low-lying sites may be unsuitable despite otherwise favourable conditions.

=== Water availability ===

Access to water, whether through natural rainfall, soil water-holding capacity or regulated irrigation, is a central consideration. Chronic [[water stress]] may limit [[yield]] and [[vine]] longevity, while excessive water availability can compromise balance and fruit concentration.<ref>Jackson, ''Wine Science'', Academic Press, 2020, ISBN ~~978-0128161180~~.</ref>

Regulatory constraints on [[irrigation]] may further influence site suitability in certain regions.
