Pomum Cellars is owned and operated by the husband and wife team of Javier and Shylah Alfonso. Originally from the famed Ribera del Duero region in Spain, winemaker Javier Alfonso is determined to showcase a true expression of wine grown in the unique viticultural areas in Washington State.

Alfonso works with several vineyards in the Columbia Valley including Dubrul, Konnowac and Dineen Vineyards in the Yakima Valley, Upland Vineyard on Snipes Mountain and Elerding Vineyards in both the Yakima Valley and Horse Heaven Hills. In 2003, Alfonso planted his own estate vineyard, AD Dunn, in the Yakima Valley near Zillah with Tempranillo and Merlot.

In addition to Pomum, Alfonso also produces wines under his Idilico label which highlights Spanish varietals.

Pomum Cellars


When it comes to the source for our wines’ raw material, Pomum Cellars does not compromise. Over the years we’ve been working with some of the most respected and quality oriented vineyards in Washington State. Our non-conformist attitude and pursuit of the highest caliber wine, ensures that we strive for continuous improvement regardless of what the vintage may bring. Many years of experience has slowly narrowed our favorite vineyards to only a handful of sources. For our style, these vineyards represent the best expression of Washington state wine. These sites include Upland and Dineen Vineyard for our Tinto Tempranillo and our own Konnowac Estate Vineyard for our Bordeaux blends and Syrah.


Konnowac Vineyard is Pomum’s Estate vineyard. We have been working with its fruit since 2007 and we finally acquired it in 2019.  It was originally planted by Charles Fiola as early as 1987 and boasts stunning old vine Cabernet, Merlot, Cabernet Franc, Malbec and Petit Verdot. These last two varieties may be some of the oldest examples in Washington State. The vineyard Is located at more than 1100 ft elevation in the northwest corner of the Rattlesnake Hills AVA within the larger Yakima Valley AVA. Wines made from Konnowac fruit show unique personality yet maintain focused varietal purity. Konnowac fruit is the source of the majority of our Bordeaux and Syrah wines.
