Specialty Coffee — Freshly Roasted

Anaerobic

Controlled Fermentation. Elevated Flavor.

Controlled fermentation. Elevated flavor.

Fermentation as craft. Roasting as calibration.

Every lot is engineered — sealed environments, measured temperature, a roast profile dialled in for the bean in front of us. Precision is the shortcut to flavor.

Each lot dialled to its own window — shorter for floral, longer for funk.

Our Philosophy

Fermentation as Craft

We believe that controlled anaerobic fermentation unlocks flavor profiles impossible to achieve through conventional processing. Each lot is meticulously calibrated — from cherry selection to fermentation duration — to reveal the full potential of every origin.

Transparency, producer to cup

Meet the producers.

We source from farms doing the hardest work — experimental fermentations, varietals pushed to their limits, microlot discipline. Every bag names the hands behind it.

Loved by Coffee Enthusiasts

Ethiopia Sidama Anaerobic Natural

The Ethiopia Sidama completely changed how I think about coffee. The blueberry notes are unreal — it tastes like coffee at the top of its range.

The Double Shot — Subscription

The subscription is a game-changer. Every two weeks a new origin shows up and it's always a surprise. Last month's Panama Geisha? Unreal. My mornings have genuinely never been better.

Colombia 72h Anaerobic Natural

I ordered the Colombia 72h Anaerobic Natural Pink Bourbon on a whim and it blew me away. The fruit complexity is like nothing I've had before. Already reordered.

Costa Rica - 36h Anaerobic Honey

I've been into specialty coffee for years — Anaerobic still caught me off guard. The Costa Rica had this caramel-meets-citrus thing that I've never tasted in a honey process. Only reason for 4 stars: I wish they had bags bigger than 10oz.

Brazil Mogiana Natural

Added the Brazil Mogiana to round out my order — just a classic natural, as I wanted a solid daily drinker alongside the anaerobics. It's honestly great on its own. Rich, chocolatey, no gimmicks.

Peru Gesha Anaerobic

Bought the Discovery Set as a small gift for my partner. We both fell in love with the Peru Gesha — the jasmine and tropical fruit notes were incredible.
