Frequently Asked Questions
Everything you want to know about our coffee, process, and how we operate.
About Us
What is Coastal Granny's Collective?
We're a San Diego-based micro-roastery and mobile café run by Ryan & Kelly McLaughlin. Ryan roasts specialty coffee on an Aillio Bullet drum roaster — focusing on experimental co-ferments, carbonic macerations, and rare single-origins. Kelly runs the coffee and matcha cart at pop-ups and events around San Diego.
Do you have a physical location?
We operate as a roastery and mobile café. Our coffee ships direct from San Diego, and Kelly's cart pops up at local markets and private events. Follow us on Instagram to find out where we'll be next.
Why does your coffee cost more than grocery store coffee?
A few reasons: every bag is roasted to order on a specialty drum roaster (not mass-produced months in advance), and many of our lots use experimental processing methods that require significantly more time, labor, and precision at the farm level. Anaerobic and co-fermented coffees can cost producers far more to produce than conventionally processed lots — and that's before accounting for the cup quality that results. You're paying for something genuinely different.
Do you source ethically?
Yes. We work with importers and producers who prioritize transparent supply chains, fair pricing to farmers, and sustainable practices. The experimental processing methods we favor — co-fermentation, carbonic maceration — are also labor-intensive techniques that reward producers who invest in quality, which aligns with how we think sourcing should work.
Are your coffees organic or fair trade certified?
Most of our coffees are not formally certified organic or fair trade — and that's worth explaining. Certification is expensive and logistically difficult for small farms, which means many of the most ethical, quality-driven producers in the world simply can't access those labels. We focus instead on direct relationships through trusted importers who can speak to how a farm operates, how workers are compensated, and how the land is treated. We'd rather know the story behind a coffee than rely on a sticker.
Are some coffees seasonal or limited?
Yes — many of our experimental lots are produced in small quantities and won't be back once they're gone. When a coffee sells out, it's gone. If you spot something you love, don't wait. We're working on a restock notification feature so you can get alerted when a lot returns or something similar comes in — in the meantime, follow us on Instagram where we announce new arrivals first.
Where can I follow the cart schedule and new coffee drops?
Instagram is the best place — we post pop-up dates, new lot announcements, and behind-the-scenes roastery and cart content there regularly. You can find us at @coastalgrannys.
Our Coffee & Processing
What is co-fermented coffee?
Co-fermented coffee is specialty coffee that ferments alongside living cultures from craft beverages — things like Belgian abbey ale, white wine, hazy IPA, tepache, or even fruit grown on the farm itself. The flavors develop naturally at the molecular level inside the green bean during processing. Nothing is added after roasting. The result is coffee that tastes genuinely unlike anything else — notes like lavender, purple grape, papaya, or tropical fruit that would be impossible in a conventionally processed lot.
Is co-fermented coffee the same as flavored coffee?
Not at all. Flavored coffee has syrups or oils applied to already-roasted beans. Co-fermented coffee undergoes biological fermentation while the beans are still green. The flavors are built into the coffee itself — nothing is added, nothing is artificial.
Does co-fermented coffee contain alcohol?
No. Fermentation happens at the green coffee stage, long before roasting. The high temperatures of roasting eliminate any residual alcohol. What remains are the aromatic compounds that give each lot its distinctive character.
What is carbonic maceration?
Carbonic maceration is a fermentation technique borrowed from winemaking. Whole, unpulped coffee cherries are placed in airtight barrels filled with CO₂. The oxygen-free environment causes the cherries to ferment from the inside out — breaking down pectins and producing complex aromatic compounds that get absorbed directly into the bean. Because the cherries stay whole throughout, the process is slower than standard anaerobic fermentation and can take months. The result is typically a bright, fruit-forward cup with strong notes of red fruits and stone fruit.
What is the difference between aerobic, anaerobic, and carbonic maceration?
Aerobic fermentation incorporates oxygen, causing sugars to break down rapidly. Anaerobic fermentation removes oxygen and lets sugars ferment slowly in a sealed environment — this produces more complex, layered flavors and is the basis for most of our experimental lots. Carbonic maceration is a specialized form of anaerobic fermentation where whole cherries (not just pulped beans) ferment internally in a CO₂-filled barrel. Each method produces a distinct cup profile, and small changes in temperature, time, sugar content, and the type of microorganism present create dramatically different results.
How does experimental fermentation affect quality?
When done well, experimental fermentation can meaningfully elevate a coffee's cup score, complexity, and market value — a lot that might score 83 as a standard washed coffee could reach 86 or higher with a carefully managed extended fermentation. The key word is carefully: uncontrolled fermentation can produce off-flavors, chemical notes, or mold. The farms and producers we work with treat this as a precision process, not a shortcut.
What is a single-origin coffee?
Single-origin means the coffee comes from one specific farm, region, or producer — not blended from multiple sources. It lets you taste a place: the soil, altitude, climate, and processing choices of one particular lot. Most of what we carry is single-origin because we want you to be able to trace exactly where your coffee came from and why it tastes the way it does.
What does 'specialty grade' mean?
Specialty grade is the top tier of the coffee quality scale. Coffees are scored on a 100-point scale by certified Q Graders — specialty grade starts at 80 points, with truly exceptional lots scoring 90+. It means no defects, clean sourcing, and a cup that stands on its own without milk or sugar. Everything we carry is specialty grade.
Where does your coffee come from?
Our catalog spans over 10 countries — Colombia, Ethiopia, Hawaii, Indonesia, Vietnam, India, Papua New Guinea, Costa Rica, and more. We focus on farms and producers known for fermentation-forward processing, and every origin we carry is one we can speak to by name.
What does 'roasted to order' mean?
It means we don't roast in advance and store bags in a warehouse. When you place an order, your coffee gets roasted, cooled, and packaged before it ships. You receive coffee at its peak freshness — typically within days of leaving the drum.
Brewing & Storage
How should I brew co-fermented or carbonic maceration coffee?
Pour over, AeroPress, and French press all work beautifully and let the full flavor range come through. We recommend a medium-coarse grind, water around 200°F, and a brew ratio of 1:15 to 1:17. These coffees reward a little slower pour and a little more attention.
Can I make espresso with these coffees?
Yes. Several of our coffees pull beautifully as espresso and shine in milk drinks. That said, filter brewing tends to reveal the full complexity of the fermentation process. If you're curious about a specific lot for espresso, reach out and we'll point you in the right direction.
What roast level should I choose?
For experimental and co-fermented lots, we generally recommend Light or Light-Medium — lighter roasts preserve the aromatic compounds developed during fermentation. Heavier roasts will overshadow the nuance. For more classic origins like our Indonesian or Hawaiian offerings, Medium or Medium-Dark can bring out chocolate and body beautifully.
What grinder should I use?
A burr grinder (as opposed to a blade grinder) makes a significant difference with specialty coffee. Consistent particle size means even extraction and a cleaner cup. You don't need to spend a fortune — a good entry-level hand grinder will outperform most electric blade grinders.
Does water quality matter?
More than most people expect. Coffee is over 98% water, so what's in your water ends up in your cup. Heavily chlorinated tap water can dull or distort flavors, especially in delicate co-fermented and light-roasted lots. Filtered water (a simple Brita works) makes a noticeable difference. Fully distilled or softened water is too mineral-free and produces flat, lifeless coffee — you want some mineral content, just not chlorine or off-flavors.
How should I store my coffee?
Keep your coffee in the bag it came in — the one-way valve lets CO₂ escape without letting oxygen in, which is exactly what you want. Store it sealed, at room temperature, away from heat, light, and moisture. Avoid the fridge: the temperature fluctuation and ambient odors do more harm than good for everyday use. The freezer is only worth it for long-term storage of a completely sealed, unopened bag — once you've opened it, keep it at room temp and brew it within 2–4 weeks of the roast date. If you want to go a step further, vacuum-sealed containers (like Fellow Atmos or Airscape) are excellent for extending freshness — they actively remove oxygen from the container rather than just sealing it in. They're especially worth it if you buy in larger quantities or tend to go through a bag slowly. Just avoid clear containers; light degrades coffee faster than most people realize.
When is my coffee at its peak?
Most specialty coffees hit their sweet spot between 5 and 21 days post-roast. Right after roasting, the beans are still off-gassing CO₂ and the flavors can taste a little flat or sharp. After about 3–4 weeks, oxidation starts to dull the complexity. Our experimental lots often have a slightly wider peak window — some are even better at 12–15 days.

Coffee Cart & Events
What does Kelly's coffee cart serve?
The cart serves specialty espresso drinks, matcha lattes, and seasonal menu items at pop-ups, markets, and private events around San Diego. Same care and intention as the roastery — just mobile.
Why matcha?
Matcha and specialty coffee share a lot of the same values — sourcing matters, preparation matters, and there's a real difference between commodity and craft. Kelly has developed a matcha program that fits naturally alongside the coffee, especially for events where not everyone drinks coffee.
Can I book the cart for a private event?
Yes. We do private events, corporate gatherings, weddings, and pop-ups. Head to our Coffee Cart page to submit an inquiry and we'll get back to you with availability and details.
