"12 Ranch Wines"  is a small family owned winery located in Bonanza, Oregon. We specialize in small, handcrafted lots of Merlot, Cabernet Sauvignon and Syrah.  Our grapes are hand picked from select vineyards in the Rogue Valley of Southern Oregon. We work very closely with all our vineyards through out the growing season, especially when it gets close to harvest. We must not forget that a great wine begins in the vineyard. Sugar, acid levels and when to harvest are just a few of the decisions our vineyards allow us to make. Discretion over the growing process, not “adjustments” during winemaking, let the grapes natural varietal flavor come through. Our wines reflect the true qualities of each vintage.

Wine glasses This wonderful fruit is brought to our facility in Bonanza, hand sorted into the crusher /destemmer  and placed into stainless steel fermentation tanks. They are fermented, with the grapes, or cap being punched down by hand 3 times a day to keep skins wet and to extract that great deep dark color.
Next, we press the wine off the skins into oak barrels. The wine is aged in Hungarian oak barrels which adds to the complexity of the wine, but still allows the great flavor of the fruit to come through. Our wines are unfiltered and we use only gravity flow methods to gently handle our wines. With our small lot production we are able to pay close attention to each wine at every step of the way.


Wine making at "12 Ranch Wines" is a family affair. Ken and Connie Masten are the wine makers, sales team, and sanitation or clean up crew and best of all, in charge of tasting for quality control. Our daughter, McKenzie is the best helper of all. She loves "getting into her work"  and can be found hauling stems away from the


crusher/ destemmer or digging the skins out of the press, which is her favorite job. Even our Australian Shepherd, Kairo, helps out. 
Grape picking He loves riding in the trailer to unload the grape stems and greeting visitors. We have no employees, but have been blessed with great friends that help us during  crush, and are always available for tasting. We couldn't have made it without their help and support.
We were born and raised in the Bonanza area, graduated from local high schools and McKenzie attends the same school  as Connie did. Our families have been in this community for five generations. In addition  to the winery, we have a ranch and raise hay, grain, and cattle. The area is abundant with wildlife and ranch life. The deer and cranes feed in the pastures along side the cows and calves. In the spring and fall the Canadian and Snow geese are migrating through and stop to feed Mastens
 in our fields on the ranch.

Because of our love for good wine and interest in winemaking we are fulfilling our dream of remaining in our hometown, raising our family and producing great wines.

Our plans are to stay small so we can focus on each of our wines, and hopefully get to know you as you're enjoying the fruits of our labors. We truly hope you enjoy our wines as much as we enjoy making them and bringing them to you. We would love to have you stop by for a visit and do some tasting. We're located in Bonanza Oregon 20 miles east of Klamath Falls.


This was and is the original write up for our Winery when we opened back in 2004. As in all parts of life time goes on! That cute little girl playing in the grapes is now all grown up  and living in Portland Oregon. She is following her dreams and care path, but thankfully is still very involved wit the Winery, our events and does all our graphic design work She will actually be home for the Memorial Day Open House. We also have another Australian Shepard, Quincy, here with us and boy does he love people, so plan on being greeted by him!
