Our take

What we make of this bottle

Sauvignon Blanc is the grape on this label, and our grape research describes it as a white variety known for a clear, aromatic character and lively acidity, usually made dry, though sweetness and oak use vary. Across the category, official guides point to citrus, fresh green herbs, gooseberry and tropical fruit, with cooler vineyards leaning green and citrusy and riper fruit turning more tropical. The wine is from California, and Grounded Wine Co. says Napa native Josh Phelps started the company as his own label. We do not have a shopper rating for this wine.

In our September 2026 checks the shelf price fell between $16.99 and $18.99 across the two stores that stocked it. That citrus and green-herb profile is what the guides expect from the grape, though the bottle in the glass is where the taste is settled.

Grounded Wine Co.'s own account names who is behind the label: winemaker Josh Phelps grew up in a Napa winemaking family and worked harvests alongside his father, Chris Phelps, also a winemaker, before starting this brand on his own. For the 2024 vintage, the producer's technical sheet confirms the wine is 100 percent Sauvignon Blanc at 13 percent alcohol, picked about two weeks earlier than usual after a light crop, then fermented cold in stainless steel tanks to protect the natural acidity. The producer's own tasting notes describe white peach, lime and Meyer lemon zest, with what the winemaker calls “natural tension” carrying through the finish.

Our call: reach for this if a named winemaker's own hand and a full technical sheet are what you want behind an everyday Sauvignon Blanc; Josh Phelps names the exact blend, the alcohol, and the harvest choices for this vintage. Pass if you want the crowd's confirmation first; no shopper rating has reached our record yet, so the producer's own account is what this bottle offers.

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 guideSauvignon Blanc

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

Getting to know Sauvignon Blanc.

Sauvignon Blanc is a white grape known for wines with clear aroma and refreshing acidity. It is usually made as a dry still wine, though sweetness and oak use vary.

Category guide

What to expect in the glass

Official regional guides describe citrus, green herbs, gooseberry and tropical fruit across the category. Cooler sites can emphasize green and citrus notes, while warmer or riper fruit can lean more tropical.
