Small streams and ravines dissect the gentle slopes and swales of this appellation creating a complex landscape with mostly north- and east-facing slopes. During the dry summer months, the headwaters of these streams, some originating at the base of the Niagara Escarpment, serve as a reliable water resource for vineyards. In the spring, excess surface runoff and groundwater are easily drained away into Lake Ontario. The higher elevation of the bench combined with the airflow patterns of the escarpment allow for cooling breezes in summer warming breezes in winter to reach the entire appellation.
The mineral rich soils and complex landscape of the Beamsville Bench provide ideal conditions for growing grapes. Sloping vineyards backed by the escarpment, moderating breezes and excellent drainage all contribute to the natural character of the wines from this appellation.
Soils in this appellation form a heterogeneous mixture of boulders, gravel, sand, silt and clay, as well as bits of shale, sandstone and limestone from the continuing erosion of the Niagara Escarpment. This complex mix has resulted in soils that have a relatively high water holding capacity but with good drainage in the sub-soils. This provides an important advantage in dry summers when rains are insufficient for growth, and make the land particularly well suited for viticulture. Dolomitic limestone is an important component in the soils and is thought to have a direct impact on the mineral character found in many Beamsville Bench wines. The soils also show a striking visual feature - variegated colours of red, yellow and olive clays occurring in approximately equal proportions - which reflect the colours of the shale and sandstone bedrock.
The combination of short slopes of moderate steepness, high elevation and lake breeze circulations moderate both day and night temperatures and lead to a very small range of temperatures from day to night during the growing season. Heat tends to accumulate across the appellation, beginning in May and continuing well into the third week of October, establishing a long growing season and fully mature, well ripened grapes at harvest time.
The relatively high elevation of the area and the almost continuous lake breezes even out the heat, and keep the humidity in the vine canopy in check during the warm months of July and August.
