The Twenty Mile Bench, found within the boundaries of the Niagara Peninsula, stretches east to west from Fifteen Mile Creek to west of Cherry Avenue. The sheltered north-facing slopes and the air circulation from Lake Ontario provide for year round temperature moderation, setting up an ideal growing season for quality grapes. The soils consist of clay and till, with a high proportion of limestone and shale. These soils are well drained, and their density and water-holding capacities provide a definite advantage during the warmer period of the growing season when precipitation is limited .
