You ever walk into a coffee shop and immediately feel like you’re in a science lab where the scientists actually have souls? That’s the vibe. Medina River Coffee Roasters isn’t just another spot to grab a lukewarm latte before sitting in I-10 traffic for forty-five minutes. Honestly, it’s a bit of a local obsession for people in San Antonio who’ve moved past the "just give me caffeine" phase and into the "I want to taste the volcanic soil of Guatemala" phase.
It’s personal.
Most people stumble upon their location on West Avenue and expect a standard neighborhood cafe. What they get is a masterclass in small-batch roasting. The owner, Christian De la Rosa, didn’t just wake up one day and decide to sell beans; the guy is a certified Q Grader. If you don’t know what that is, think of it as a sommelier but for coffee. He can literally taste defects in a bean that would taste like "regular coffee" to the rest of us. This matters because it dictates every single thing that happens inside that building.
The Obsession With the Small Batch
Let’s talk about the roasting. A lot of places buy pre-roasted beans or use massive industrial machines that prioritize volume over everything else. Medina River Coffee Roasters goes the other way. They use a small-batch approach. This isn't just a marketing buzzword. It means they can control the heat profile to a terrifyingly specific degree.
The heat. The airflow. The drum speed.
If you roast 100 pounds of coffee at once, you’re going for an average. If you roast in small batches, you’re going for a peak. You can actually taste the difference in their West Avenue Blend or their single-origin Ethiopian. In the Ethiopian Yirgacheffe, for instance, you aren't just getting "coffee flavor." You’re getting these weirdly specific notes of lemon peel and jasmine that shouldn't exist in a bean but do because they didn't burn the life out of it.
People think "dark roast" means "strong." It doesn't. It usually just means "charred." Medina River stays in that sweet spot where the sugar inside the bean caramelizes without turning into carbon. It’s a delicate balance. One minute too long and you’ve ruined a twenty-dollar bag of specialty beans.
Why the Q Grader Status Actually Changes Your Morning
Having a Q Grader at the helm is like having a Michelin-star chef at a burger joint. There are only a few thousand Q Graders in the entire world. To get that certification, you have to pass 22 grueling tests. We’re talking about identifying acids by taste and smell alone.

Because of this expertise, the sourcing at Medina River Coffee Roasters is elite. They aren't just clicking "buy" on a wholesale website. They’re looking at harvest dates, moisture content, and elevation. They understand that coffee is a fruit. And like any fruit, it has a season. If you're drinking the same "house blend" in July that you drank in December and it tastes exactly the same, it’s probably because it’s over-roasted to hide the fact that the beans are getting stale.
At Medina River, the menu shifts. It breathes. You’ll see beans from Colombia, Brazil, or Sumatra pop up and then disappear. That’s because they’re chasing the freshest crops. It’s sort of annoying if you fall in love with one specific bean, but it’s the only way to ensure you aren't drinking "dead" coffee.
The San Antonio Connection
San Antonio has a weird coffee history. For a long time, it was a desert. Then came the big chains. Then came the "minimalist" shops where the baristas look at you like you’re an idiot if you ask for cream. Medina River Coffee Roasters sits in this perfect middle ground.
It’s unpretentious.
You can go in there and talk shop about "TDS" (total dissolved solids) and extraction percentages for an hour. Or, you can just ask for a "Honey Spiced Latte" and enjoy your life. They don’t judge. The shop itself has this warm, wood-heavy aesthetic that feels more like a Hill Country cabin than a sterile tech startup. It’s located in a strip center—because this is San Antonio and everything good is in a strip center—but once you’re inside, that disappears.
Beyond the Drip: The Speciality Drinks
While the purists go for the pour-overs, you shouldn't sleep on their signature builds. The "Medina River Latte" is a staple. It’s not a sugar bomb. It uses local honey and a hint of cinnamon. It’s subtle. Most shops use syrups that taste like chemicals and corn syrup. Here, the flavors are meant to bridge the gap between the natural chocolatey notes of the espresso and the milk.
- The Cold Brew: It’s steeped for 18-24 hours. It’s dangerously smooth.
- The Espresso: They dial in their grinders multiple times a day. If the humidity changes in San Antonio (which happens every ten minutes), they adjust the grind.
- The Seasonal Stuff: They usually have a rotating menu that reflects the weather.
The Reality of Buying Local Beans
Let’s be real for a second. Buying a bag of beans from Medina River Coffee Roasters costs more than buying a plastic tub at the grocery store. Usually, you’re looking at $18 to $25 for a 12oz bag.

Is it worth it?
If you’re just putting it in a 1998 Mr. Coffee with a dirty filter, maybe not. But if you have a decent burr grinder and a French press? It’s a completely different beverage. Grocery store coffee is often roasted months—sometimes a year—before it hits the shelf. By that time, the volatile oils that give coffee its aroma are long gone.
When you buy from Medina River, the "Roasted On" date is usually within the last week. The beans are still off-gassing. When you pour hot water over them, they "bloom" and bubble up. That’s the CO2 escaping. That’s the sign of life.
How to Not Ruin These Beans at Home
If you're going to drop twenty bucks on a bag of their single-origin stuff, you've gotta treat it right.
First, get a scale. Stop using "scoops." One scoop of a light roast weighs more than one scoop of a dark roast because the dark roast is more porous and puffed up. If you want consistency, you have to weigh your coffee and your water. A 1:16 ratio is a good starting point.
Second, check your water. San Antonio water is basically liquid rock. It’s incredibly hard. If you use tap water, your coffee will taste flat and chalky. Use filtered water. It makes a massive difference in how the acidity of the Medina River beans hits your tongue.
Sustainability and Ethics
The coffee industry has a pretty dark underbelly when it comes to how farmers are treated. "Fair Trade" is a nice label, but it often doesn't go far enough. Direct trade is better. While Medina River is a smaller operation, they prioritize sourcing through importers who can verify that the money is actually making it back to the estates and cooperatives.

Christian’s background allows him to understand the technical side of the farm level. When you know how hard it is to produce a "Specialty Grade" bean (which requires a score of 80 or above on a 100-point scale), you realize why paying the farmers more isn't just a charity—it’s an investment in the future of the product. If the farmers can’t make a living, they’ll rip out the coffee trees and plant something else.
Finding the Spot
They are located at 11825 West Ave, Ste 101. It’s tucked away near the intersection of West Avenue and Blanco Road.
The parking is... fine. It’s a typical San Antonio lot. But the reward inside is a level of quality that's hard to find without driving to Austin or flying to Seattle. They also have a solid wholesale business, so you’ll see their beans being used in various restaurants and cafes around the city. If a restaurant is serving Medina River, it’s usually a sign that the chef actually cares about the end of the meal.
The Verdict on Medina River Coffee Roasters
Look, there are plenty of places to get a caffeine fix. If you want a 32-ounce milkshake disguised as coffee, there are drive-thrus for that. But if you actually like the taste of coffee—the complex, weird, fruity, nutty, earthy reality of it—this is the place. It’s a nerd’s paradise that’s accessible enough for a casual Saturday morning.
It’s rare to find a spot that handles the entire pipeline from green bean to final pour with this much scrutiny. It’s not just a business; it’s a craft.
Actionable Steps for the Best Experience
To get the most out of your visit or your bag of beans, keep these points in mind:
- Ask the Barista what’s "dialed in": On any given day, one specific bean might be hitting its peak flavor profile. Ask them what they’re enjoying most today.
- Check the Roasting Date: When buying a bag to take home, look for the stamp. For the best flavor, wait at least 3-5 days after the roast date before brewing (this allows for de-gassing), but try to finish the bag within 3 weeks.
- Invest in a Burr Grinder: If you’re buying whole beans, don’t use a blade grinder that hacks the beans into uneven chunks. An entry-level burr grinder will unlock the actual tasting notes mentioned on the bag.
- Try it Black First: Even if you love cream, take one sip of their pour-overs black. You might be surprised at the natural sweetness that comes from high-elevation beans that haven't been over-roasted.
- Attend a Cupping: Keep an eye on their social media for cupping events. It’s the best way to learn how to identify different flavor profiles and see the "Q Grader" process in action.
