Our take

What we make of this bottle

When a winery's name turns up on a California Cabernet, what are you really buying? The shelf price is a fair place to begin. Across our September 2026 checks the lowest observed price was $19.99 and the highest was $33.99.

The shopper score here is on the low side. It sits at 3 out of five, and the number of shopper ratings so far is 1. Among the wines we track, that lands near the bottom of the range.

Caymus Vineyards puts the winery's start at 1972, established by Chuck Wagner along with his parents, Lorna and Charlie Wagner Sr., and says the Wagner family owns and runs it to this day. That is the history of the winery itself, not a note about this particular bottling.

On the grape, official regional guides fill in what to expect. They describe Cabernet Sauvignon in general as a red that often builds firm, tannic wines and turns up often in blends, with black currant, cherry and plum among the usual fruit notes and possible spice where oak is used. They add that ripeness, climate and how the wine is made can carry it toward the herbal and lean or the broad and fruit-forward. For now, its shopper score is 3 out of five.

Region guideCalifornia

A little background helps this bottle make sense.

Getting to know California.

California on the label is useful provenance but weak detail about place. For these wines, sourcing disclosure, blend construction and house-style consistency carry more decision value than a generic climate paragraph.

The place

What the name means

A state-level appellation, broader than an individual American Viticultural Area. It permits a multi-region blend and does not by itself identify one climate or soil.

Weather

How grapes grow here

The state spans cool maritime zones and hot inland valleys. A California designation alone does not reveal which conditions shaped the fruit.

Soil

What lies under the vines

At state scale, sourcing and house-style construction matter more than any single soil story.

How large the region is

Reusable question
Which counties or AVAs supplied the blend, and did that mix change by release?

Places within the region

Resolution limit
County, AVA and vineyard claims begin only when the release names them.
Grape guideCabernet Sauvignon

The grape name gives context. It is not a review of this bottle.

Getting to know Cabernet Sauvignon.

Cabernet Sauvignon is a red grape grown in many wine regions. It often makes firmly built wines and is also a common part of red blends.

Category guide

What to expect in the glass

Regional authorities describe black currant, cherry and plum as common fruit references, with noticeable tannin and possible spice from oak. Ripeness, climate and winemaking can move the wine from lean and herbal to broad and fruit-led.
