Here at Brassfield, we are not only 100% estate grown, but also entirely produced and bottled on our High Valley AVA estate here in Lake County.
We walk every row, touch every vine, and taste every barrel, because we believe in doing things the right way – not the fast way. Our vines dig deep into centuries-old volcanic soil and basalt, drawing out bold, untamed character unlike any other.












From the dual exposures of the Monte Sereno Vineyard to the peak of Volcano Ridge, Brassfield Estate is defined by extremes. Blessed with a unique east-west transverse valley and planted in the top 1% of vineyard elevations worldwide, our vines battle the elements on volcanic slopes. This daily challenge yields grapes of rare strength, producing wines that are as rich in character as they are delicious in flavor.
We take stewardship of the land and of the creatures in and above it seriously. We have provided a flyway and refuge for thousands of ducks and other waterfowl on the Brassfield Estate lands. These preservation efforts form a connection between our history and the type of sustainable conscientiousness that ensures our future.
What a stunning winery! Brassfield Estate is massive and absolutely gorgeous, tucked away right by an extinct volcano. The views are incredible, the tasting room is beautiful, and the staff treated us like old friends. On top of the amazing atmosphere, the wines are top-notch and very reasonably priced for the high quality you get. If you’re anywhere near Clearlake Oaks, you have to make a stop here.
It's such a lovely estate, amazing valley and its own private volcano and vineyard. The wine is amazing and I have been a wine club member for a year now. The staff is friendly and make you feel special.
Such a beautiful estate, but even more so the wine was delicious and the host Sarah was so informative and nice to talk to! We showed up at 4:15p on our way home and she let us have a relaxing tasting and explore the estate, and the wines were a great price point for how fancy the estate is so thank you for a great last stop to our weekend!
We did the 5 glasses of wine tasting and got the charcuterie board - everything was great. We ended up getting 6 bottles of wine because of how much we liked the rose! They are also really great with explaining everything about the wine, and they will let you retry anything you would like. The staff is very knowledgeable! You feel like royalty just being here because of how beautiful it is. My boyfriend's family has been here a lot and has always mentioned how beautiful it is. This was my first time and we will be back!
Twenty-one years ago, we set out to capture the raw, untamed energy of our unique high-elevation terroir. Nestled alongside an ancient cinder cone, the volcanic sands and tephra of our Volcano Ridge Vineyard forced our vines to struggle for water and nutrients — concentrating exceptional flavor, structure, and intense characteristics into every single berry.
The result was Eruption, a proprietary multi-varietal red blend that has proudly defined the bold, luxurious spirit of Brassfield Estate Winery for over two decades.
We invite you to join us at our high-elevation estate to celebrate this monumental milestone for our signature release. Whether you want to lounge in the Tasting Room or deep-dive into the science of our soils, we have an unforgettable day planned for you.
