Substance Wines were originally created with a mission to produce exceptional wines, from meticulously sourced sustainably grown grapes from premier Washington vineyards. Winemaker Brennon Leighton continues this practice using native yeast fermentation, lees aging, and minimal SO2 to allow for a true expression of the vineyard and to capture the unique qualities of each season. Every bottle in the Substance portfolio reflects Brennon’s commitment to purity and quality, embodying real wine for real people, crafted to be enjoyed every day.

We talked with Brennon, who has more than 20 years of experience in winemaking about his approach and dedication to crafting wines that reveal the authentic character of Washington’s terroir. We also talked about his place in the WA Wine Industry and that “One Voice” all the Washington State wineries speak to.

    Let's talk Washington wine!

    I think the story of Substance is really a story of wanting to make something that is substantial and something that is really special at a very good price. That was the initial idea of it, to go out there and do all the things that you would do to make a super extraordinary wine, and to put it into a bottle that was affordable for a lot of people.

    How did you go about this?

    We treated the vineyards like they were lower intervention vineyards, and creating that atmosphere, but also trying to create it where we can keep the value in the wines. The transformation of what we were trying to do as a winery was to create something that had the attributes of something that was really special and well-made and expensive, but for a really good price. And that was the whole intention behind Substance. Planting vineyards with closer spacing, doing lower yields, to doing 100% native fermentation in these huge, giant tanks. This was something which no one had ever really done before; doing native fermentation in 75-ton fermenters, and doing barrel aging, and all the stuff that you would do for something that costs $80 a bottle, not something that was so much less than that. That attention to detail. That’s what Substance is all about.

    How does Substance fit into the whole Washington wine collaboration?

    When Jeff O’Neill bought Substance, it was a really perfect match. For Substance, it felt necessary. It was a bridge for us to continue and to grow as what we needed to grow. One of the things that O'Neill really helped us achieve was doing 100% sustainability and actually helping us create and form a sustainability organization in Washington, and also introducing us to regenerative viticulture. We were already going in that direction, and just their 100% belief in this, this making wine and growing grapes in this way has kind of, like, boosted us up and kept us going in the direction that we always wanted to go. So, it's been the best thing that can have ever happened to Substance. O'Neill coming in and adopting us. It feels really good, it feels natural, it feels… important. It feels all these things that have been incredibly good for us. I've also sold other labels to other people, and the transition is usually really messy, and gut-wrenching, and not fun, and this has been the complete opposite.

    And sustainability is something that seems to be very important up in Washington. I mean, from everyone I've talked to, and from all the winemakers, it’s something that just keeps coming up. That and how unique WA terroir is.

    It's a totally different place to make wine than anywhere else in the world. And that's what makes it special, whether that's what makes it, I think it's what makes it intriguing as well, but whether people gravitate to that or not is a totally different story, but to me, there's something very special in Washington. I think that there's something very unique in Washington wines. I mean, everybody says that, no matter where they're from.

  5. TM
    The Mark Wine Group

    Exactly. Everyone speaks to the uniqueness.

    I truly believe that there is something, and I can taste that, and I think that people who have experienced Washington wines can also experience that. I think that it's really hard to take the Washington grape growing experience out of the wines that you're tasting. No matter how much you tried, that character comes through in more ways than one, and… I think that’s the magic.

Substance Sauvignon Blanc, Columbia Valley

A beach day in a glass: grapefruit, lime zest, and orange peel cut by a piercing minerality. Native-fermented from sustainably farmed Columbia Valley fruit, this 91-point James Suckling charmer is bright, electric, and built to make you smile.

Substance Sauvignon Blanc, Columbia Valley bottle

Substance Chardonnay, Columbia Valley

Elegant and mineral-driven, with apple blossom, lemon curd, and a whisper of salted caramel over a long, focused finish. 100% native fermentation from premier Washington vineyards earns this beauty 93 points from James Suckling, refined winemaking, raw and real.

Substance Chardonnay, Columbia Valley bottle

Substance Rosé, Columbia Valley

Provence-pretty in the glass, with tangerine, wild strawberry, and a kiss of crushed seashell. A 91-point James Suckling single-vineyard Pinot Noir off Evergreen's limestone soils, native-fermented and impossibly easy to fall for.

Substance Rosé, Columbia Valley bottle

Substance Pinot Noir, Columbia Valley

Take a deep breath and surrender: wild strawberry and black raspberry meet chanterelle, crushed gravel, and forest floor. This 90-point James Suckling stunner is native-fermented from Golden West and Evergreen fruit, elegant, complex, and quietly unforgettable.

Substance Pinot Noir, Columbia Valley bottle

Substance Red Blend, Columbia Valley

Dark, juicy, and alive, with black plum and dried blueberry layered with black licorice. A 93-point (James Suckling), native-fermented blend of sustainable Washington fruit that delights the casual sipper and the aficionado alike.

Substance Red Blend, Columbia Valley bottle

Substance Cabernet Sauvignon, Columbia Valley

Bold, polished Cabernet bursting with cassis, blackberry, and a touch of suede, finishing impossibly smooth. Native-fermented from eleven premier Columbia Valley vineyards and rated 92 points by James Suckling. Serious Washington Cab that overdelivers.

    The literal geography of the state.

    Brennon Leighton

    Right. There's a unique perspective and voice that Washington wines have. And I think that they're important to the wine industry, and I don't think that that has been expressed very well.

  2. TM
    The Mark Wine Group

    Yeah, and that actually gets to the whole concept of our partnership with the WA State Wine Commission.

    The Mark Wine Group

    Brennon Leighton

    Yeah, I think that there's a voice that is beckoning to be heard. I do think at times it has been heard, but, you know, I certainly think that it's in a place where we really need to spread the word. Most of the wines that are coming out of Washington, that most people get to taste, are not really the core or what makes Washington special. It’s been really hard to get those wines outside of Washington.

  3. TM
    The Mark Wine Group

    And that’s exactly where we come in. We are super excited to introduce our national account buyers to all of Washington State wine.

    When you look at our little neighbors to the south of us in Oregon, and how they've been very good at expressing who they are and what they do. They got the message out to the world of what to expect from Oregon wines. This is something we need to do. We need to celebrate our uniqueness.

  4. TM
    The Mark Wine Group

    Which is where the WA Wine Commission has really come into play.

    The Mark Wine Group

    Brennon Leighton

    Yes. It’s a really exciting time. To have a shared voice. It’s all about defining what Washington wine is, whether it’s viticulturally, winemaking practices or marketing. We are truly at a point in Washington's history to be on the map for who and what we are. Almost like a rebirth in who we are for the future generations of winemakers and wine people that are going to be part of this industry for a long time. We need to get our voice out there and really show what Washington is. Washington itself can find a really powerful voice in this industry.

    Relaunch, reignite and re-inspire.

    I’ve spent 15 years trying to put Washington State on the back labels and sell Washington State. Finally, we have the opportunity to really do that. I think this is a really positive time for the Washington wine industry.

  2. TM
    The Mark Wine Group

    Anything new we should know about Substance?

    The Mark Wine Group
    Brennon Leighton

    Brennon Leighton

    We're just about to release a Riesling under the Substance label. Everyone's extremely excited about it. You know, one of the things I have a plethora of experience of making is Riesling. I don't think there's very many people in the world that have made as many gallons of Riesling as I have. I've been making Riesling for a long time and I think the Riesling that just got released is a really special Riesling. I think it has a lot of expression and a lot of perspective, and I'm really excited about what other people think about it. I'm getting a lot of good feedback about it. So, I think that's the buzz coming from Substance right now.

  3. TM
    The Mark Wine Group

    This is super exciting. The real expression of Washington Riesling.

    The Mark Wine Group
    Brennon Leighton

    Brennon Leighton

    Absolutely. It comes from one of my favorite vineyards in Washington State called Evergreen Vineyard. The soils are primarily limestone and a lot of basalt and volcanic soils so it has this really pure minerality to it. And really beautiful aromatics.

  4. TM
    The Mark Wine Group

    So excited to try it. And to sell it! Thank you so much for this.
