Ser Dry Riesling Wirz Vineyard 2017
In the tradition-bound world of wine, winemaking has, predictably, been dominated by men. For example, there are about 4,800 wineries in California, but only 10 percent have female lead winemakers. (When it comes to winery ownership, the number does jump up to about 19 percent, according to Woman Owned Wineries, a nationwide directory of female wine entrepreneurs.)
Encouragingly, however, greater educational opportunities (as opposed to the historically more usual inheriting a wine operation) have been opening the possibility of becoming a winemaker to more and more women. One of these is Nicole Walsh of Ser Winery in Aptos, California, due east of Santa Cruz.
The winemaker
Over the course of her over 19 year career, Walsh has held just about every position in the wine industry, including associate winemaker, winemaker, vineyard manager, grower-relations manager, and owner. She was born in Saginaw, Michigan, in 1975. An early interest in wine drew her to Michigan State University, graduating with honors in 1998. At the time, the undergraduate department of Viticulture and Enology there was, remarkably, comprised of just two students. This provided a highly unusual opportunity to be immersively mentored by Horticulture professors in grape growing and winemaking. As part of her last semester at MSU, she attended a sustainable agriculture university, EARTH, in Costa Rica. While there, Walsh became proficient in Spanish, and she solidified her commitment to sustainable agriculture.

After graduation, she worked for four years on the Leelanau peninsula in northern Michigan. This small AVA (one of five in Michigan) is home to 27 wineries, and has diverse microclimates uniquely suited to cool-climate wine grapes, particularly Riesling, Chardonnay, Pinot Grigio, Pinot Noir, and Cabernet Franc. During her time there, she managed vineyards and honed her winemakeing skills.
In early 2001, she married Kevin Walsh, and together they moved to Santa Cruz, California. Shortly thereafter, in February, she started working with Randall Grahm at Bonny Doon Vineyard.
Walsh took a sabbatical from Bonny Doon in 2008, when she moved with her husband and young son to Marlborough, New Zealand. After a year, she returned to Santa Cruz to develop Bonny Doon’s newest property in San Juan Bautista. She continues to manage that property as well as make wine at Bonny Doon’s Santa Cruz winery.
In 2012, reflecting on her New Zealand experience, especially with Pinot Noir, Walsh decided to start her own wine brand as well, which she christened Ser, which is Spanish for “expressing identity or origin; having the intrinsic quality of.”
“I was inspired for the name after reading an article by Andrew Jefford, ‘Wine and Astonishment’. It was in that writing that the notion of the ‘being’ of wine truly resonated with me. Being is different than existing. It is true, wine exists; you can touch it, smell it, drink it. To quote Jefford, ‘Being, by contrast, is the ‘isness’ inside.’ In other words, the natural essence of the grapes unique to each specific growing area. I am dedicated to preserving the ‘isness’ of wine, to allow its true varietal expression and the place and time of its origins,” shared Walsh. Clearly, this thinking closely aligns with the traditional concept of terroir.
She continued, “Jefford also talks of that first moment of insight, that moment when some people decide to devote their professional life to wine. He says,’It gives the lucky few who choose to ‘grow wine’ the chance to use craft to embody, reflect, and echo nature itself.’ I am privileged to be one of those ‘lucky few.'”

Once the winery was underway, she began working with local Santa Cruz Mountain growers to purchase fruit from a number of interesting vineyards with distinct microclimates in the appellation. In symbiotic partnership with those farmers, she started experimenting with several varieties, such as Riesling and Chardonnay (both of which she had worked with on Leelanau), Syrah, Mourvedre, and a much less-known variety, Cabernet Pfeffer. She is committed to preserving and enhancing the unique character of the varietals used in her wine.
Ser’s label, designed by local artist and teacher Jenny Angelacos, was inspired by an ocean wave and Walsh’s love of surfing. It is intended to convey the unifying thread that connects the diverse places from which she sources her grapes.

Ser Dry Riesling Wirz Vineyard 2017
OK, I’m going to be honest about this up-front: although Riesling is, by all accounts, one of the world’s greatest white-wine grapes, and makes classic food-friendly wines in a range of styles from quite dry to very sweet, I’ve never been much of a fan. But I enjoyed this expression, so kudos to Ms Walsh.
The fruit came from the Wirz Vineyard, located in San Benito County’s Cienega Valley, in the foothills of the Gabilan Mountain Range at about 1100 feet above sea level and 25 miles or so from the Pacific Ocean. It is composed of granite and limestone soil. Owner Pat Wirz employs head training, dry farming and organic techniques on the over 90-year-old Cabernet Pfeffer and 60-year-old Riesling vines.
In “head training,” vines are tied to a wooden stake positioned at each one. The stake generally stands three to four feet above the soil surface. When used conservatively, this system is ideally suited to production of low to moderate quantities of high-quality grapes.
To make this wine, Walsh pressed whole grape clusters in stainless steel, which was also used for fermentation. She used an indigenous yeast, and the wine was bottled prior to malolactic fermentation to lend softness without stripping the acidity. It is medium yellow in the glass, with a nose of olive oil and delicate floral notes. These are followed by mostly tart citrus on the palate, particularly lime, with subtle hints of pear and apple. It’s balanced out by that good acidity, and wraps up with a medium finish. The ABV is 13% and 160 cases were made.
Other Ser wines
Although I haven’t tried them, in addition to this selection Ser Winery also offers Rosé of Cinsaut (a red-wine grape from Languedoc-Roussillon, usually characterized by a light body, high acidity, and low tannins), Sparkling Riesling, a second Pinot Noir from the Santa Cruz Mountains, and yet a third (!) Cabernet Pfeffer. There is a wine club with three shipment options, the easiest and most reliable way to obtain these limited-production wines.
