Our take

What we make of this bottle

This is a red wine from France's Rhône Valley, sold in a 750 ml bottle. Regional guides describe the Rhône as stretching from hillside vineyards in the north to a much wider spread of countryside in the south, and note that the two ends do not share one climate, with the south catching more of the Mediterranean warmth and the Mistral wind. The name on this bottle is Côtes du Rhône, one of many protected appellations inside that broad region. The same guides are clear that Côtes du Rhône, Côtes du Rhône Villages and the named crus each draw their own boundaries and follow their own rules. In our September 2026 checks the store listing put it between $18.99 and $25.49 across three stores.

We do not have a shopper rating for this bottle. The grape or grapes are not something we can confirm; what Château de Saint Cosme does say is that the estate has stayed in the same family since 1490.

Region guideRhône Valley

A little background helps this bottle make sense.

Getting to know Rhône Valley.

The Rhône links northern hillside vineyards with a much larger southern landscape. A Rhône Valley reference gives regional context, but the exact appellation still matters for grapes, place and production rules.

The place

What the name means

The Rhône Valley is a broad French wine region containing many protected appellations. Côtes du Rhône, Côtes du Rhône Villages and named crus have different boundaries and rules.

Weather

How grapes grow here

Northern and southern parts of the valley do not share one climate. The south has stronger Mediterranean and Mistral influence, while the long river corridor and surrounding landforms create local differences throughout the region.

Soil

What lies under the vines

Granite, clay, limestone, sand, stones and other river and slope deposits occur across the valley. The northern and southern vineyards use these soil groups in different combinations.
