2023 Hanna Sauvignon Blanc 750ml

Russian River Valley

Vineyards: Our Slusser Ranch fruit is the single largest contributor. The blend also includes fruit from Barnwell, Shone Farms, Redwood Glen, Mirabelle, Ottar and Cameron.

Russian River Valley 2023: Another wet winter followed by a cool spring and summer allowed clusters to size above expectations. Continued moderate temps in late summer and early fall resulted in slow ripening and a harvest that was a month later than 2022 with bright acids, and fresh flavors. We had no heat waves and ended up with 2700 Degree-Days at our Slusser vineyard. Our 2023 Sauvignon Blanc was harvested between September 6, and October 19, 2023. The grapes were harvested at an average of 22.5° Brix, TA of 0.75 g/100 mL, and pH 3.29.

Winemaking: Our winemaking begins in the vineyard. We manage the canopies to promote photosynthesis and protect clusters from heat and light from fruit-set on. Harvesting is done at night by hand or machine depending on vineyard infrastructure and block size. Press cuts on all lots are de rigueur. Our Sauvignon Blanc is fermented and aged in stainless steel tanks, which keeps the wine fresh and bright. Bottling typically takes place from January to July at monthly to bi-monthly intervals.  

Winemaker’s notes: We grow and vinify our Sauvignon Blanc to be fresh, vibrant, and evocative of the grapes themselves. We have chosen a tin lined screwcap closure—unsurpassed in its ability to retain our wines exuberance. Please note that proper conservation requires cool, even temperatures and the absence of light. 

We have included Thiol and Pyrazine analysis below. Thiols are naturally produced in the fruit and liberated by fermentation. Their concentration is reported in parts per trillion! They are important contributors to Sauvignon Blanc varietal character. 3MH is described as passion fruit, grapefruit. 3MHA is described as boxwood, cat pee or passion fruit, and 4MMP is described as guava and boxwood. Pyrazine is also naturally produced in the fruit. Its aromas are described as bell pepper, or herbal.  This is not an exhaustive list!  Many other compounds not listed- or elucidated for that matter- are contributory.

Tasting Notes: A joy-eliciting rush of orange blossom, guava, key lime, cosmic crisp apple, Anjou pear, and fresh basil emerge upon pouring. Flavors of tangelo, mango, fennel, Valencia orange and passion fruit follow in this delectable, poised, Russian River youngster. (Tasted 2/27/2024)
