Prati by Louis M. Martini Cabernet Sauvignon Sonoma California Red Wine

19 shoppers have rated this wine, at an average of 4.16 out of five, which sits in the bottom quarter of the ratings among the wines we track. The grape is Cabernet Sauvignon and the maker is listed as Louis M. Martini, though we have not confirmed an account from the producer for this bottle. The price changes from one store to the next.

Cabernet Sauvignon is a red grape grown in many regions; regional authorities say it often makes firm wines and is often part of a blend. They describe black currant, cherry and plum as common fruit notes, with noticeable tannin and possible spice from oak, and they say ripeness, climate and winemaking can push it toward lean and herbal or toward broad and fruit-led. The wine is from California, and Sonoma appears in its name, but that name does not settle which of those styles is in the glass. One of the September 2026 checks put the bottle as low as $14.99.

By August 12, 2026, the most a store asked for the same wine was $26.99. Across the seven stores in those September 2026 checks, the same Cabernet carried prices anywhere between the two.

Our call: the current shopper ratings argue for patience here; the shoppers who have scored this Sonoma-named Cabernet put it in the bottom quarter of the rated wines we cover. It suits a buyer drawn to the Martini name who gives little weight to shopper ratings, and anyone shopping by score should pass until the average tells a better story.
