Why Robusta Extracts Faster Than Arabica (And What That Means)

Why Robusta Extracts Faster Than Arabica (And What That Means)

Consider this your morning briefing: You roasted two City+ batches on your SkyWalker 2—one Arabica, one Robusta. The results? The Robusta shot extracted in 10 seconds with a coarse grind, then 20 seconds with a finer setting. The Arabica? Perfect, at size 12. This isn’t a fluke. Robusta’s physical and chemical makeup demands a different approach. Robusta beans are denser, harder, and more compact than Arabica. Their structure resists water flow, but only up to a point. When ground too coarsely, Robusta’s particles act like a sieve, letting water pass too quickly. That’s why your first shot was under-extracted. Switch…

Mastering Light Roasts on the Huky 500: A Roaster’s Dilemma

Mastering Light Roasts on the Huky 500: A Roaster’s Dilemma

The Huky 500 is a beast of a roaster—until you try to coax it into a light roast. For those chasing the delicate, floral notes of Ethiopian naturals or the bright acidity of Rawandans, the machine’s strength lies in its medium roast comfort zone. But dialing back to light? That’s where the real work begins. The challenge? Balancing first crack timing, development window, and heat management without letting the beans bake before they even crack. The core issue hinges on temperature control. Most users report first crack erupting around 410–422°F, which is already in the medium roast territory. To hit…

Mt. Apo’s Hidden Gem: Filipino Arabica That Defies Expectations

Mt. Apo’s Hidden Gem: Filipino Arabica That Defies Expectations

The verdict is in: Filipino Arabica from Mt. Apo isn’t just a curiosity—it’s a revelation. Sourced from the biodiverse highlands of Mindanao, these beans challenge assumptions about what coffee can be. Roasted to a light to medium profile, they reveal a complex interplay of earthy notes and citrus brightness, proving that geography and care can elevate even imperfect raw material. The beans, a Catimor variety from the Mt. Apo region, arrived with a troubling flaw: worm holes marred their surface, reducing density and raising questions about quality. Yet, the roast test results spoke volumes. Three iterations of espresso extraction yielded…

Profitec Go’s Double Dilemma: Should You Chase the Manual’s 60 mL?

Profitec Go’s Double Dilemma: Should You Chase the Manual’s 60 mL?

The Profitec Go’s owner’s manual says a double espresso is 60 mL. Is that your new target? A user on Reddit is grappling with this exact question, having dialed in their machine to pull 36g from 18g grounds in 25 seconds. The shot tastes good, but the higher yield of 60 mL feels like a missed opportunity. If you’ve ever wondered whether to follow the manual or trust your palate, this is your moment. The Profitec Go’s extraction window is narrower than many home machines, which means small adjustments in grind size or dose can tilt the balance. The user’s…

GS3 vs. GS4: Should You Invest in La Marzocco’s Iconic Machine or Wait for the Next Big Thing?

GS3 vs. GS4: Should You Invest in La Marzocco’s Iconic Machine or Wait for the Next Big Thing?

Get ready to sip on this: The La Marzocco GS3 is a beast, but is it worth the $8000 price tag—or should you wait for the next big thing? If you’re eyeing an upgrade from a Profitec Pro 700, you’re likely chasing steam power, temperature stability, and volumetrics. The GS3 delivers all of that, but its 2008 design feels like a relic in a world of rapid innovation. The Linea Mini’s recent “R” update and the Strada X1’s $20k price tag have left many wondering: Is the GS3 a relic, or still the gold standard? The GS3’s appeal lies in…

Why Your Bambino+ and Smart Grinder Pro Keep Choking—And How to Fix It

Why Your Bambino+ and Smart Grinder Pro Keep Choking—And How to Fix It

Pour yourself a cup for this one: Your Bambino+ and Smart Grinder Pro are choking on single-wall unpressurized baskets, and it’s frustrating. You’ve tweaked dosages, adjusted grind settings, even cleaned the machine—but the problem persists. It’s a puzzle, and the solution might not be what you expect. The root of the issue likely lies in a combination of burr alignment, dosage precision, and machine calibration. You’ve tried 14g to 15g dosages with outer burr settings at 5 and 6, yet the shots still choke. This suggests the grinds are too fine or uneven, creating a compacted puck that blocks water…

A CF64v with a Lelit Victoria, and I’m a sweetness junkie. Whether it’s a light roast’s citrus zing or a dark roast’s molasses depth, I crave balance.

Does the Steam Wand Angle Matter for Microfoam? Here’s the Truth

Does the Steam Wand Angle Matter for Microfoam? Here’s the Truth

Listen up: The steam wand angle is a hot topic in barista circles, and for good reason. Whether you’re chasing velvety microfoam or perfect latte art, the angle at which you position the wand can make or break your results. But here’s the catch—most baristas debate it like it’s the final round of a championship, when the real answer is simpler. You’ve probably seen videos showing every angle from 45 degrees to straight down, each claiming to be the holy grail. Yet, the science behind it? Less clear. The truth is, the steam wand angle isn’t a one-size-fits-all solution. It’s…

Mastering the Cortado: Consistent Foam, Crisper Art

Mastering the Cortado: Consistent Foam, Crisper Art

Here’s something to stir your curiosity: the cortado’s magic lies in the balance between milk and espresso, but achieving that harmony feels like chasing a ghost—until you nail the routine. For those of us who prefer less milk, the Silvia’s precision can feel like a double-edged sword. It’s a machine that demands respect, and when you finally sync with its rhythm, the results? A cortado that’s creamy, crisp, and utterly satisfying. The Silvia’s strength is its pressure, but that same force can turn a simple froth into a mess if you’re not careful. The key? Temperature. Milk that’s too cold…

Real talk: If you're dreaming of a coffee shop but can't afford the lease, here's a smarter play.
