Do Okanagan wines contain Sulphites?

Yes, almost all Okanagan wines contain sulphites, but the levels are usually low and safe for most people. Here’s a clear explanation using Canadian spelling and context.

Sulphites in Okanagan wines — the facts

  • Natural sulphites — All wines (red, white, rosé, sparkling) produce sulphites (sulphur dioxide, SO₂) naturally during fermentation. Even wines labelled “no added sulphites” still have small natural amounts, typically 10–40 ppm (parts per million).
  • Added sulphites — Winemakers add extra sulphites as a preservative to prevent oxidation, spoilage, and unwanted bacteria. This is standard practice in Canada and worldwide. Total sulphite levels in most Okanagan wines range from 20–150 ppm — often lower in reds (20–80 ppm) and higher in whites, rosés, and sweeter styles (80–150 ppm).
  • Regulatory limits — Health Canada allows up to 350 ppm in wine. Most Okanagan producers stay well below that, usually under 100 ppm, because the cool climate and low disease pressure allow minimal intervention.

Organic and biodynamic wines — lower sulphites

Organic and biodynamic wineries in the Okanagan generally use fewer added sulphites (or none at all), making them a good option if you’re sensitive or prefer minimal intervention:

  • Organic wines — Under the Canada Organic Regime, added sulphites are limited (often capped at 100 ppm total, but many producers add little or none). Natural sulphites only remain.
  • Biodynamic wines — Certified biodynamic (Demeter) producers follow even stricter natural principles. Many add no sulphites or only trace amounts to preserve the “living” character of the wine.

Notable examples on Kelowna & West Kelowna routes:

  • Summerhill Pyramid Winery (East Kelowna, on many Kelowna wine routes) — Certified organic and biodynamic, uses no added sulphites in most wines (only natural levels, often <20–40 ppm). Known for clean, expressive, low-intervention wines.
  • Kalala Organic Estate Winery (West Kelowna upper bench) — Fully organic, minimal or no added sulphites.
  • Off the Grid Organic Winery (West Kelowna area) — Organic focus, low-intervention, low-sulphite wines.
  • Other low-intervention producers on the West Kelowna wine route (Lakeshore Road, Mount Boucherie) also prioritize minimal or no added sulphites.

My take as a guide: From leading hundreds of tours, I’ve never seen a guest have a sulphite reaction. Most sensitivities are actually to alcohol, histamines, tannins, or dehydration — not sulphites. Guests who are cautious do very well with organic or biodynamic wines like those from Summerhill or Kalala — cleaner feel, still full of flavour. We can point out these options on tours or include them on private routes when requested.

Red Dog Wine Tours visits a range of wineries, including organic and biodynamic ones with low or no added sulphites — just let us know your preferences when booking.

As of 2026, Okanagan wines remain safe, delicious, and — for those sensitive — increasingly available with minimal sulphites.
