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.

Vintage 2019

2019 CABERNET SAUVIGNON
SIGNATURE RELEASE | NAPA VALLEY
2019 marks the second vintage we’ve used the Melrose Vineyard in the northern part of Rutherford and bordering St. Helena. Managed by Beckstoffer, Melrose produces classic Napa Valley Cabernets and share a lot of similarities to Cabernets from Oakville. For the 2019 vintage, we created a blend that is 95% Cabernet Sauvignon with Merlot, Petit Verdot, Malbec and Cabernet Franc. Like the 2018 vintage, this wine has character, elegance, texture, and balance. Grainy tannins pair nicely with lively acidity and integrated oak to compliment the richness of the fruit. This wine will continue to develop and gain complexity over the next 10-to-15 years. Rated 91 points.

2019 CABERNET SAUVIGNON
LIMITED RELEASE | HOWELL MOUNTAIN
2019 marks a return to Howell Mountain. Our first wine under the Prothro Family Wines label was a 2014 Howell Mountain Cabernet Sauvignon. That wine won a Gold Medal at the San Francisco International Wine Competition and was rated 90 points. Sourced between 1,800 and 2,000 feet of elevation, the 2019 is just as stunning with impressive fruit, nice tight tannins, and a backbone of acidity. The depth and assuredness of this wine is amazing. While it is beautiful now, this mountain grown wine will benefit from some bottle age. We expect this wine to develop and gain complexity over the next 12-to-18 years. Rated 93 points.

Our Cuvée no. 6 Red Wine is a big Merlot based wine. It’s been described as a baby Cabernet and is 96% Merlot finished with Cabernet Franc and Petit Verdot.

This is a rich wine with completeness across palate and a lasting finish. With immediate appeal, we expect it to develop and gain complexity over the next 7-to-12 years. Rated 91 points.

2020 CABERNET FRANC
RED WINE | NAPA VALLEY
The 2020 Cabernet Franc is big and structured with an elegant entry, fullness on the mid-palate, and a lasting finish. Elegant with darker to blue fruits, pronounced dark cherry, a nice touch of floral notes, and slight herbaceous undertone. 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. This wine has immediate appeal but will continue to develop and gain complexity over the next 7-to-10 years. Rated 93 points.

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.

2020 CABERNET SAUVIGNON
HERITAGE RELEASE | RUTHERFORD
The 2020 Heritage Reserve Cabernet is sourced from one of the most iconic and legendary vineyards in the Rutherford AVA. Originally known as Beaulieu Vineyard 3, this vineyard produces wines that are everything you would expect from a world-class Rutherford Cabernet Sauvignon – dust, black cherry, dark plum, cassis, current, cocoa, cedar, and barrel spice. 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. This is an outstanding Cabernet that should continue to develop and gain complexity over the next 10-to-15 years. Rated 93 points.

Vintage 2021

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.
