Bottle label for 2022 Prothro Sauvignon Blanc

2023 SAUVIGNON BLANC
WILDWOOD VINEYARD | SONOMA VALLEY

The 2023 Wildwood Sauvignon Blanc is our first from this vineyard owned by the Knude family. It expresses citrus, melon, guava, white stone fruit, dried hay, and wet stone minerality. Some Semillon and a touch of Pinot Grigio adds weight to the mid-palate helping the wine to be expansive with a long, crisp finish. An elegant and graceful wine that should continue to develop in the bottle over the next 5 to 7 years.

Prothro Family Wines 2020 Rosé wine front label

2020 ROSÉ
HERINGER ESTATE VINEYARD | Clarksburg

Our 2020 Rosé is dry, crisp, and complex. This is a serious wine with great balance and texture. We harvested Tempranillo and Mourvèdre from the Heringer Estate Vineyard in Clarksburg to create a very Mediterranean styled Rosé. Strawberries, watermelon rind, rhubarb, and white peach are exhibited on the nose with weight on the mid to back palate. The wine finishes with wonderful, crisp, juicy acidity. We have found our Rosés benefit from a little bottle age and continue to develop complexity over a few years.

Brix at Harvest: 21.9 (Tempranillo), 21.4 (Mourvèdre)

Bottle label for 2020 Prothro Cabernet Franc

2020 CABERNET FRANC
RED WINE | NAPA VALLEY

Big with depth and muscle, it is what you would expect from wine sourced from this legendary vineyard and from a block located 1,400 feet up Atlas Peak.

2020 CABERNET SAUVIGNON
SIGNATURE RELEASE | NAPA VALLEY

2020 is our third harvest using the Melrose Vineyard in the northern part of the Rutherford AVA, which is managed by Beckstoffer. We love Melrose and the classic profile of the Cabernet it produces. The wine has character, elegance, texture, and balance. You can feel the grainy tannins, lively acidity, and integrated oak that compliment the richness of the fruit. This is classic Napa Valley and an example of what put its Cabernets on a world stage. We fully expect this wine will continue to develop and gain complexity over the next 10-to-15 years. Rated 91 points.

HERITAGE RELEASE | RUTHERFORD

The 2020 Heritage Reserve Cabernet is sourced from one of the most iconic and legendary vineyards in the Rutherford AVA.

Lush, opulent, and balanced, there is a touch of grainy tannins with crisp acidity and integrated oak adding to the weight and texture in the mid palate and a lingering finish on the back palate.

2021 CABERNET SAUVIGNON
RED WINE | NAPA VALLEY

2021 marks a return to the Broken Rock Vineyard, which we used from 2015 through 2017. Broken Rock Cabernets are structured, powerful, and brooding. They open slowly to reveal dark fruits, coca, graphite, and anise with great acidity and subtle tannin. These wines are a little “old school,” and can age 10-to-15 years.

2021 CABERNET SAUVIGNON
LIMITED RELEASE | HOWELL MOUNTAIN

Howell Mountain is the Holy Grail to winemakers. These grapes were sourced between 1,800 and 2,000 feet on Howell Mountain. The 2021 is a stunning wine with impressive fruit, nice tight tannins, and a backbone of acidity. While it is beautiful now, this mountain grown wine will benefit from some bottle age, and we expect this wine to develop and gain complexity over the next 12-to-18 years.

2021 LIMITED EDITION ZINFANDEL
MOON MOUNTAIN DISTRICT | SONOMA COUNTY

The 2021 Limited Edition Zinfandel, sourced from a very fabled and iconic vineyard dating back to 1886, is a balanced expression of what this grape can do. Driven by tones of raspberry and blackberry, with just enough spice, this wine has good acidity and just a slight touch of tannin. It’s full and lively on the palate while maintain structure and depth. Versatile but focused, this wine rewards patience and time in the glass. While great out of the bottle, the 2021 Limited Edition Zinfandel will easily develop over the next 7 to 10 years.
