About The Wine


The Dry Stack Vineyard rests 550 feet above sea level on the eastern slope of Mt. Taylor. The soils are marine clay loam with many small to medium sized stones throughout the profile, helping drainage and soil texture.


Robert Parker Jr. describes this site as, “Dry Stack Vineyard in Bennett Valley is one of California’s best examples of this Italian clone of Sauvignon Blanc that is planted in these gravelly, loamy soils.”


This fruit was hand harvested and brought on a cool morning in the begining of October, close to a month after the area’s other Sauvignon Blanc was harvested due to the cool site location and coastal influence. Jesse lightly whole cluster pressed the fruit to a stainless steel tank where he let the juice chill at 50˚F for two days to settle. On the third day, the team cleaned and racked it to a smaller tank leaving the heavy sediment behind. Three days later, the fermentation started naturally and they kept the fermentation below 56˚F until half the sugar was consumed. At 12 brix they transferred the young wine to barrels. Jesse used neutral French oak  barrels, 1/3 once used French oak barrels, and 1/3 new French oak. The wine was placed in our cold room to keep the fermentation cool and slow, keeping freshness and aromatics bright. As the wine slowly fermented for an additional month in barrel, he topped and stirred each barrel weekly. The wine stayed in those same barrels for 6 months and stopped malolactic fermentation in order to keep the natural bright acidity.


As Jesse Katz studied the art of winemaking in Bordeaux, he spent some time at Haut Brion’s cooperage, where he found a barrel unlike anything he had seen before in the US. He tasted through the Haut Brion Blanc barrel by barrel and found that they used an individual custom oak, that imparted a profile to the wine, that he loved. He knew he wanted to incorporate this distinctive barrel into Aperture’s first white wine. Jesse then shipped these unique French oak barrels with acacia barrel heads and Haut Brion’s own signature toast from Bordeaux to California. 


Aperture Sauvignon Blanc 2019

  • "The 2019 Sauvignon Blanc Dry Stack Vineyard is blended with 4% Sémillon in the style of a Bordeaux Blanc and has extraordinary appeal this year. It opens with classic notes of gunflint and smoke that flesh out to a peachy core accented by notes of beeswax, lychee, floral perfume and ripe citrus. The palate is dynamic, medium-bodied and textured but bursting with ripe, mineral-laced fruits, buzzing with bright acidity and finishing long and addicting. I find it hard to resist drinking this immediately, although it could age well in bottle."

    "From the cooler Bennett Valley, the 2019 Sauvignon Blanc is terrific, offering juicy notes of white peach, nectarines, and exotic flowers to go with a medium-bodied, balanced profile on the palate. It's another classy, beautifully made white from this estate."
