Nuclear Cat Coffee was born out of a simple idea: coffee should taste alive. For too long, we kept running into stale beans on grocery shelves, bitter brews in cafés, and "premium" bags that didn't feel worth the price. We knew there had to be a better way — so we started roasting in small batches with a focus on freshness, transparency, and community.
Our name reflects the kind of energy we want to put into your mug every morning. Just like a nuclear reactor powers entire cities, a single cup of great coffee has the power to fuel your day, spark your ideas, and keep you moving. But unlike mass-market brands, we don't operate at factory scale. We roast on a human scale, where quality and care matter more than volume.
Every batch is sourced with intention. We partner with farms and importers who share our values — fair treatment, sustainable practices, and pride in their craft. Once the green beans arrive in Portland, we roast them in limited drops, cupping each roast until we're confident it shows off the best flavors the coffee has to offer. That's why our bags don't sit on shelves for months; they move straight from roaster to customer, hitting your doorstep at the peak of flavor.
But Nuclear Cat isn't just about coffee. It's about people. We donate a portion of our profits to community programs that support local growth and resilience. We believe coffee is more than a product — it's a connection between farmers, roasters, and drinkers. Every purchase supports not only your mornings but also a bigger mission of positive impact.
Whether you brew espresso at home, prefer a moka pot, or just love a solid drip cup, Nuclear Cat Coffee is here to elevate your ritual. We're committed to freshness, flavor, and fairness. From our hands to your mug, this is coffee that doesn't just wake you up — it keeps you inspired.

Understanding how coffee is processed after harvest dramatically affects the final cup. The washed process, also known as wet processing, involves removing the cherry and mucilage before drying, resulting in clean, bright flavors with pronounced acidity. Natural processing leaves the cherry intact during drying, creating fruity, wine-like characteristics with fuller body. Honey processing, a hybrid method, removes the skin but leaves some mucilage, producing balanced sweetness and complexity. Each method requires specific climate conditions and expertise, making the choice of processing method crucial to achieving desired flavor profiles in specialty coffee.
Light roasts preserve the origin characteristics of the coffee, showcasing floral, fruity, and acidic notes. The beans reach first crack but don't progress much further, maintaining higher acidity and caffeine content. Medium roasts balance origin flavors with roast development, creating caramelization that adds sweetness while preserving some acidity. This roast level offers the most balanced cup for most palates. Dark roasts develop past second crack, creating bold, smoky flavors with reduced acidity and origin characteristics. The roasting process becomes the dominant flavor, producing oils on the bean surface and creating the classic "coffee" taste many associate with traditional brewing methods.
Water temperature significantly impacts extraction: too hot (above 205°F) and you'll over-extract bitter compounds, too cool (below 195°F) and you'll under-extract, resulting in sour, weak coffee. Grind size controls extraction rate - finer grinds extract faster but can lead to over-extraction, while coarser grinds extract slower but may under-extract if contact time is insufficient. The coffee-to-water ratio determines strength: 1:15 to 1:17 ratios work well for most methods. Extraction time varies by method - espresso extracts in 25-30 seconds, pour-over in 4-6 minutes, and French press in 4 minutes. Mastering these variables allows you to dial in the perfect cup for your taste preferences.
