The agricultural district around the town of Summerland on the west shore of Okanagan Lake, historically the heart of the BC tree fruit industry. The lake's influence is pronounced here — summer fog and moderate temperatures produce more restrained, aromatic wines than the southern desert zones. Pinot noir, riesling, and pinot gris are well-suited to the conditions.

Vintage assessments

2021	89	Heat dome conditions followed by a clean, extended autumn. Pinot Gris and aromatic whites particularly successful.
2020	81	Smoke curtailed the normally reliable Summerland growing season. Riesling harvested early showed clean fruit; most reds were compromised.
