Winemakers Notes: Summer In The Cellar With Margaret Davenport
July is always a great month to be working in the cool of a wine cellar, and the air conditioning was even more welcome this year. Temperatures were at record-breaking levels for over two weeks, and many growers used their frost protection systems, if they dared spend the water, to sprinkle the vines in order to provide some relief from the heat. Vines literally shut down, leaf stomates close, and no photosynthesis occurs when temperatures surpass the upper 90s. Veraison, which means berry softening and coloring, is beginning in early whites like Sauvignon Blanc and early reds like Zinfandel.
Meanwhile, back in the cool cellar among the barrels, many things are happening. The 2004 Cabernets were racked for the last time in May. The Reserve Cabernet from blocks 18 and 19 on the Passalacqua Ranch is sitting on egg white finings, which are a very gentle treatment to smooth out rougher tannins that may be too astringent or drying on the entry and midpalate. The Cabernet blend from blocks 2 and 13 has already been transferred to tank. Both Cabs were bottled during the third week of July.

The 2005 Dry Creek Valley Barrel Fermented Chardonnay has also been racked for the first time and left to chill for two weeks prior to filtering and bottling. As the wine is gently pumped to tank, bentonite and isinglass are added to clarify the young wine and compact the primary fermentation lees. The wine had been in barrel since last harvest, and the lees had been stirred every three weeks. This procedure hastens the malolactic fermentation; continued stirring makes for a richer, smoother-textured Chardonnay. The Chardonnay also was bottled during the third week of July.
The 2005 Zinfandels were all racked, blended, and returned to barrel in early May. We made six very unique Zins in 2005. The Sonoma County Zin is an appellation blend, using fruit from Alexander and Dry Creek Valleys. Alexander Valley Zins signature is intense flavors of raspberry fruit, while Dry Creek Zin contributes the pepper and exotic spice to the blend. Our Russian River Zin displays the same crushed berry and white pepper as the 2004, a pleasantly light-bodied but precocious winemerriment in a bottle! The Dry Creek Old Vine blend, sourced from several vineyards along the eastern bench of the valley, is dark, deep and rich. It has a savory character that pairs well with game and heavier, sauced dishes.
For 2005, we are presenting three vineyard-designated Zinfandels. The first is our own Passalacqua Estate Zinfandel, which you pass on your way to the tasting room (often, we hope!). Next time youre here, take a look at the gnarly old vines that produce this classic Zin. The younger vines are Petite Sirah, for a future field blend. Since 2004 we have also been making a Zin from Tom and Tina Maples vineyard along Dry Creek Road, just south of the Dry Creek Store. Their loving care in the vineyard helps to make this a truly special wine. Theyve put together a Zin field blend for us, consisting of Petite Sirah and Carignane. Lastly, weve made Primitivo with grapes from our friends Scott and Bill at Lavender Hill Vineyard, high above West Dry Creek Road. The vineyard is young and the resulting wine is vibrant and racy, with a raspberry-cranberry component overlaying a unique spiciness. We only have three barrels this yearthankfully, theyre planting more!
All of these Zins will be racked from barrel for the last time in August, then bottled just before harvest preparations begin. Weve already received some of our new French oak for the vintage. Soon well be moving in equipment from storage at the ranch, including the open-top fermentors, the press, and the crusher-destemmer. And its almost time to order yeast for each wine and take out the refractometer for vineyard visits
So, the cycle continues in our world of wine.
