From Ground to Glass: Discover the Terroir Behind British Columbia Wines

One of the key drivers behind the continued growth of British Columbia’s wine industry is the establishment of Geographical Indications (GIs) and Sub-GIs. These designations recognize the distinct terroir of winegrowing regions across the province and offer consumers a clearer understanding of where their wine comes from.

What Are GIs and Sub-GIs?

GIs serve as official appellations of origin, similar to France’s AOC or Italy’s DOCG systems. They’re used to define and protect specific wine-producing areas, ensuring wines labeled from a region truly reflect the character and quality of that place.

There are currently 9 Geographical Indications in BC:

• Okanagan Valley

• Fraser Valley

• Similkameen Valley

• Vancouver Island

• Gulf Islands

• Shuswap

• Thompson Valley

• Kootenays

• Lillooet

Within the Okanagan Valley GI, there are 11 officially recognized Sub-GIs, each reflecting microclimates, soil types, and unique topographies:

• Golden Mile Bench

• Golden Mile Slopes

• East Kelowna Slopes

• South Kelowna Slopes

• Lake Country

• Summerland Lakefront

• Summerland Valleys

• Okanagan Falls

• Skaha Bench

• Naramata Bench

Outside of the Okanagan, Vancouver Island is home to one recognized Sub-GI: Cowichan Valley.

Why GIs Matter to Wine Lovers

Under BC’s Wines of Marked Quality Regulation, wines bearing the VQA (Vintners Quality Alliance) symbol must contain 100% BC-grown grapes. For those labeled with a GI designation, at least 95% of the grapes must come from that specific GI, with up to 5% allowed from other parts of BC.

These standards help:

• Assure authenticity and traceability

• Promote agri-tourism and wine education

• Encourage quality winemaking and regional identity

Many producers have gone further by offering single-vineyard wines or small-lot bottlings, highlighting hyper-local terroir. Even within the same sub-GI, individual vineyards may have unique soil compositions, aspects, and elevations, offering wine lovers a deeper, more nuanced “sense of place.”
