Six Sigma Ranch and Winery

Absolutely stunning place, the ranch and lands are gorgeous. The tasting facility is very cozy and the wines taste great. Friendly service and a shop where you can buy meat, cheese and of course their wine ! We will be back !

This was so sigma

My girlfriend and I recently had the pleasure of staying at the Six Sigma Ranch and Winery, a destination we eagerly anticipated as our first experience with Harvest Host. From the very beginning, the reservation process was a breeze, guided by a remarkably friendly staff member who gave us a concise and informative preview of what to expect during our visit.

Our journey to the ranch in my 32' RV was a peaceful one; Spruce Grove Rd, a charming, meandering county road, set the stage for the serene escape that awaited us. The final leg involved a 2-mile drive on a well-maintained dirt road, easily navigable in my Class C motorhome by maintaining a cautious speed.

Upon arrival, the warmth of the welcome we received from several winery personnel was genuinely refreshing. Check-in was conducted with utmost professionalism, and we were handed a detailed folder outlining all our stay essentials. We were then directed to the barn where we could choose any spot—we opted for spot #6, which offered a splendid view overlooking the winery.

The highlight of our visit was the deluxe wine tasting accompanied by a delightful charcuterie board, which we enjoyed on the winery’s porch. The staff's attentiveness made us feel special and added to the exceptional experience. As the day wound down, we purchased a few bottles of wine and retreated to our RV, soon finding ourselves enveloped in the tranquil solitude of the estate.

The evening brought a magical twist, with local wildlife appearing as we cooked dinner in the designated BBQ area at the winery. This added an enchanting element to our culinary experience under the stars. Please note that Verizon wireless service is spotty in this area, and the winery's WiFi does not reach the barn. Generators are prohibited from 10 PM to 8 AM, and no open flame campfires or cooking outside your RV are allowed.

For those who relish the quiet of the night and the sounds of crickets, this place is a slice of heaven. Six Sigma Ranch and Winery is not just a place but an experience that we eagerly anticipate reliving this fall. Whether you are a seasoned RV traveler or a Harvest Host newcomer, I recommend adding this destination to your travel list.

Six Sigma never disappoints! The entire crew made us feel welcome. The charcuterie board was the perfect touch to go with their amazing wines. Thank you for a memorable afternoon.

The experience was awesome after the visit of the cave followed by a wine tasting ?

Good wines - predominantly reds. The reserve Cab Sav is outstanding The staff are wonderful, so friendly and welcoming and the owner, Kai, is a top guy

A great place to relax. A beautiful environment with beautiful hiking trails. The wine tasting is very good. A place to come back to.

Six Sigma Winery is a great place to escape to and experience some great wine. The location is ideal if you are looking for peace and quite and a country setting.

Such a lovely winery filled with activities for the whole family and more importantly - delicious wine! Christian is a wonderful host who made our family feel welcomed; he was knowledgeable and personable. The property is filled with activities for all ages, which is hard to find in a winery. Their wine is delicious, especially their Wildflower Picnics Rosé. One sip and I told my husband that we weren’t leaving without a bottle of it, so he bought 3. For those who love sweet wines, it is a must have. The only downside is that our family lives 10 hours south of here in SoCal, but luckily they ship so I’ll never have to go without!Thank you Six Sigma - we are so glad we found you!

A great, out of the way winery in Clearlake area. Large amount of acreage dedicated to mountain biking, bike races , hiking and horseback riding. Quench your thirst with the Rosé. If you are lucky, the owner has a PUCH military transport that shuttles you to your car. If you hook up with the bike race organizers, you get to camp in the meadow with your tent or RV for the race events.

We enjoyed a great wine tasting at 6σ. The staff was very kind and generous. Craig, particularly, was a great server and enjoyable to get to know more during our tasting. Additionally we really enjoyed the G.O.A.T charcuterie while we were out there. The property is very beautiful and worth the trek.

It was our first time attending a mountain bike race located here at the Six Sigma winery. The lush green rolling hills cut in with trails is just amazing. How wonderful that they host the races every year - AND let teams/families camp on-site. We took a stroll down the road for some wine. I purchased the red blend and some cheese the gal behind the counter recommend. I very much enjoyed both. I highly recommend this winery ?.

The staff is awesome. Their wine is great and the catered food is the best when paired with the wine when they have a gathering.

We have been wine club members here for over a year now. It is a huge ranch with a small family feel as it is family owned & operated. There is plenty of room there for our kids to play. Definitely a great winery to bring friends and family. We recently went to their international Tempranillo day celebration & was a fantastic time. The wine maker explained each wine that paired with the meals in a fun manner. This wine club is a keeper for us as it has a lot to offer with its membership & the wines are excellent.

Fantastic ranch and winery in Calistoga. It’s a 4600 acre property with not just the winery but tracks for mountain biking, camping, gimping, and hiking.
