If you’ve ever driven past our vineyard and thought, huh, those vines look kind of wild — you’re not wrong. No wires. No neat rows strung up like a fence. Just short, gnarled trunks standing on their own, arms reaching out in every direction like a bunch of little wooden candelabras. That’s called head training, and it’s one of the oldest ways to grow a grapevine. It’s also the reason we’re able to dry farm. (more…)
Most wine mistakes aren’t about the bottle you picked. They’re about the temperature you’re drinking it at. Rosé should be served fridge-cold, and red wine — yes, even a bolder one like Zinfandel — usually tastes better a little cooler than “room temperature,” which most of us set our thermostats to around 68–72°F anyway. That’s warmer than any red wine actually wants to be served. (more…)

Here’s the whole method, before we slow down and explain it: look at the wine, swirl it, smell it twice, then take a real sip and let it sit on your tongue before you swallow. That’s it. That’s the entire “skill” that sounds so intimidating in a tasting room. Takes about thirty seconds. No vocabulary required.
We pour this wine for a living, and we can tell you — nobody at our table is grading your sentences.
Somewhere along the way, wine got a reputation for being a test. Like there’s a right answer, and if you say “I taste cherry” instead of “notes of morello cherry with a whisper of forest floor,” you’ve failed somehow. You haven’t. Wine tasting isn’t a vocabulary exam — it’s just paying attention to something for a few extra seconds before you drink it.
So let’s take it one step at a time, using an actual glass — say, our Grenache Rosé, since it’s the bottle we open for people who aren’t sure they’re “wine people” yet.
Tilt the glass slightly against something plain — a napkin, a white tablecloth, your own hand. What color is it? Pale pink? Deep gold? Bright ruby? That’s genuinely all you need to notice here. Color can hint at style and sometimes age, but for a Tuesday-night glass, you’re just looking so your brain has something to compare against once you smell it.
This part looks like showing off, but it isn’t. Swirling the glass — small circles, glass resting on the table if you don’t trust your wrist yet — pushes air into the wine and pulls more of its aroma up out of the glass. It’s the difference between smelling a flower from across the room and holding it under your nose.
Pro tip: if you’re worried about spilling, keep the base of the glass on the table and just rotate it. Nobody will notice, and it works exactly the same.
Stick your nose into the glass and take one real inhale. Then do it again. This is the step people rush, and it’s the one that matters most, because most of what you register as “taste” actually comes from smell.
You don’t need fancy words. Ask yourself simple questions instead:
There’s no wrong answer. If all you get is “smells like a rosé,” that counts.
Take a real sip, not a polite little taste. Let it sit on your tongue for a second before you swallow, so it touches all sides of your mouth. Now notice:
If your mouth waters a little after you swallow, that’s acidity — it’s what makes a wine feel refreshing instead of flat. If your tongue feels a little dry or gripped, especially with a red, that’s tannin. You don’t need the words. You just need to notice the sensation is there.
| Myth | Fact |
|---|---|
| You need to name specific flavors to “get it right” | There’s no scorecard. “Tastes like berries” is a complete, correct answer |
| Swirling is pretentious | Swirling releases aroma — it’s functional, not performative |
| You should hold the glass by the stem or you’re doing it wrong | Hold it however’s comfortable; body heat warming the wine slightly matters more for reds you’re sipping slowly over an hour, not a quick taste |
| If you don’t like a wine, you have “bad taste” | Taste is personal. Some people love bold tannins; some don’t. Neither is wrong |
| Real wine tasting requires spitting | Spitting is for people tasting a dozen wines in a row so they don’t get overwhelmed — not for a glass at dinner |
The reason people swirl wine before smelling it isn’t tradition for tradition’s sake — it’s physics. Swirling increases the surface area of the wine exposed to air, which releases more aroma compounds into the space above the glass, right where your nose is waiting. It’s a small, useful trick, not a performance.
If someone said “let’s go wine tasting this weekend” and you pictured a two-hour drive to Napa, traffic on the 101, and a $45 tasting fee just to sit down — good news. Contra Costa wine country is about 50 miles east of San Francisco, tucked into the flat, sun-warmed land around Knightsen, Brentwood, and Oakley, and most people who live thirty minutes away have no idea it’s there. (more…)
Someone in our tasting room picks up a bottle almost every weekend and asks the same question: “Why does this one look different from that one?” It’s a fair question. Wine bottles aren’t shaped the way they are by accident — the shape is inherited from old European wine regions, and it still tells you something useful before you’ve read a single word of the label. Here’s what the shapes actually mean, and why every bottle we make at Corteza is shaped the same way on purpose. (more…)
There’s a reason serious winemakers from the Bay Area and beyond have been quietly sourcing grapes from eastern Contra Costa County for years. It’s not a trend. It’s the ground. Here’s what makes this corner of California so good for growing wine grapes — and how to get the fruit, or the wine, from our family vineyard in Knightsen. (more…)

If you’re looking to buy wine grapes in the East Bay or Contra Costa area — near Brentwood, Oakley, or Livermore — we grow Carignane right here in Knightsen and we’re taking reservations for the 2026 harvest. It’s a bold red grape with a great history in California home winemaking, and it makes a wine that stands out. Here’s what it is, why winemakers want it, and how to get some. (more…)
