    By appointment only winery! A recently opening to the public by appointment only, Theorem Vineyards is such a charming spot, from design to decor, from the estate vineyard to the gorgeous Mountain View, every little detail has been meticulously built for with love. It's a bit of drive to the farthest part of Calistoga. It's 1- 1.5 hours from downtown Napa to get here. So if you were planning a day trip coming from Silicon Valley or SF, I suggest to hit Theorem Vineyards first, and other wineries along the way back down to Napa! Give yourself 1-1.5 hrs of visit, take your time and enjoy this gorgeous place. Since it by appointment only, it's never be crowded and you feel very special here. They only produce 2 wines and a few vintages back. They were fantastic wines, Estate Vineyard only, and if you a Cab lover, this hits the spot for you! They currently offer 2015, 2016 and a few magnum for older vintages back to 2012! The Hawk's Prey was great and you can enjoy it now or for later. Voir Dire is the flagship wine of Theorem Vineyards. Produced from the oldest vines on their Diamond Mountain estate, this is also 100% Cabernet Sauvignon and it is a complex, captivating and timeless wine. I would like this to lay down for a few more year so I can truly enjoy it! Under the leadership of consulting winemaker Thomas Rivers Brown, think of Schrader Cellars, Maybach, Round Pond, Double Diamond, Heston, Outpost (former), Tamber Bey, Turley (former), Kinsella, Revana, Aston Estate, just to make a few! We were greeted by the handsome and charming James. He was kind, enthusiastic and genuinely love what he does, and it's shown! We learn about the estate, the history, and the amazing fruits producing from this estate! We can't wait to come and also bring our friends/families! They produce such a small production so their wines are sourced after via their wine club members, and a few restaurants locally! Contact the estate to get your hands on these wines before it gets big and we won't be able to afford it!

    You always read about 'hidden gems', but Theorum Vineyards is just that! Not on a lot of folks' radars, but it should be! To be honest I was drawn to request an appointment simply when our daughter, an attorney, came across their label, Voir Dire, and asked me to look into it. Didn't take me long to realize this was a winery I needed to visit and learn more about. This was especially true when I noted their sixty acres of vineyards are located in the Diamond Mountain AVA, one of our very favorite locations for exceptional fruit making awesome wines! The first thing you notice, after a beautiful drive to the winery, is the old schoolhouse, which still stands. Very cool to see have kept this on site and even built the present winery to coexist so well with it! The vineyards surround the winery and looking one direction you can see progress in action as newly cleared land was ready for the planting of more vines! The winery is beautiful and modern as is their tasting room. The chandelier is an incredible thing of beauty! Speaking of beauty, the wines of Theorem (Voir Dire and Hawk's Prey at this time) are absolutely fabulous wines and the Voir Dire really hit my palate as a new favorite for sure! We came away with both the '14 and '15 vintages for our cellar. When you are putting together your itinerary for a Napa Valley visit, be sure to do yourself a favor and call for an appointment at Theorem! You will not be disappointed!

    Breathtaking first impression in the tasting room!

    Very cool winery up on a hill. Castle construction is a cool concept…read more We did the wine tasting and the juice tasting. I thought it was slightly expensive but not terrible. It was very busy. They clearly work on a volume basis compared to other wineries. Since I only like very sweet wines, I was able to find something for me.

You could tell he genuinely enjoys what he does, and he kept the tour interesting the entire time. The castle itself is stunning and the whole experience felt really unique. The wine tastings were all delicious and added a lot to the visit. The only downside was unfortunately someone in our tour group. One woman made sure everyone knew she was a member and kept mentioning how she had already seen the castle too many times and was bored of it, saying she only came to bring her family for a birthday. It kind of disrupted the experience for the rest of us. When we got to the torture chamber she also started making some really inappropriate remarks, which was a bit uncomfortable for the group. Aside from that situation, we still had a great time and really enjoyed the tour and tastings. Overall it was a memorable experience and definitely worth visiting if you're in Napa. 5 stars for Eli!!

I wish I would've gotten something special for my occasion while there. Like a signed bottle or something marking the special occasion. It was just the perfect experience all the way around. interesting that it was also the 50th anniversary of the Chardonnay that made Chateau Montelena & Napa Valley famous. Of course, we checked out and bought 2 bottles of reds at the end of the tasting without even thinking about buying the white. So disappointed that didn't occur to me to this morning. I mean the red cab's are just to amazing on there own. Ok so here is how the visit went. When we showed up early at 9:30am, we actually meant to just walk around the lake and view the birds. We made no reservations as we figured the place was fully booked for months. So we just wanted to at least see the famous vineyard.. we drove up and we immediately noticed the beautiful grounds. I mean stunning in every way. We even watched and photographed a beautiful white swan gracefully move throughout the lake. Afterwards, we walked up the path to the chateau and was presented with a old historic and charming building residence. Absolutely stunning, a complete representation of the movie bottle shock. We continued to walk around the building where we were allowed to enter the wine tasting room. At first, we were unsure of what to expect. I believe her name was Lynn invited us to have a tasting. Everyone was so gracious and nice. Just felt so sophisticated & elegant in every way. Lynn was so nice and inviting that I just wanted to say thanks to her again. You made our tasting feel amazing. We ended up buying 2 bottles of red cab when we were there to avoid paying for the tasting. I mean I'm so happy that I got to experience this winery. The history and quality wine making really is the standard for the area. A complete must visit if your ever in Calistoga. Thank you.

    We were camping at the nearby state park and were looking for a place that was open for wine…read moretasting and picked this one. It was around 5pm on a Thursday and we were the only ones around. The tasting cost $40 for 6 pours, starting with a rose and ending with a Cabernet Sauvignon. I am not very fond of reds but all the ones that were on the tasting menu that day were very good. The rose was my favorite. I was talking to the owner and he mentioned that he prefers to be out making wine instead of pouring and I can see that. Also, the pours were very tiny. There was not much information shared about the wine etc, he left the bottle with the information side turned towards you to read up on your own. The place itself is beautiful and it used to be a hardware store. It's right next to the city hall and across the street from the police station. There is street parking as well as a public parking lot next to the police station. The place is dog friendly and the owner bought out a bowl of water for my baby. I didn't buy anything but I would visit again.

We were fortunate to meet the owner, Ted, who was very kind and knowledgeable, and the wine was Excellent and a Great value. The tasting room was cute, clean, comfortable, and bright. We left with 6 bottles and wish we bought more; will be ordering more soon. We went to several other bigger/more "famous" wineries in the area, and Olabisi was our favorite. Thanks again Ted!
