How to Determine Your Pour-Over Coffee Brewing Method? How to Establish Extraction Parameters for Unfamiliar Coffee Beans? What's the Difference Between Dark and Light Roast Coffee Beans?

A good cup starts with a suitable extraction method. But with so many coffees out there, how do you know the method you're using actually suits the beans in the hopper? That's the dilemma nearly everyone faces with a new, unfamiliar bag of beans.

So today FrontStreet Coffee is sharing: how to develop a brewing method for unfamiliar coffee beans.

How to Develop a Brewing Method for Unfamiliar Coffee Beans?

Don't imagine you need to reinvent your technique from scratch. Inertia is real — once you're comfortable with a brewing method, upending it wholesale usually backfires. What you actually need to adjust is the extraction, which means adjusting the extraction parameters.

Which brings us back to the core question: with so many beans — different varieties, densities, roast levels — how do you know which parameters fit? FrontStreet Coffee's advice: read the label. For pour-over, roast level is the primary reference, because pour-over extraction essentially splits into two camps: dark roast and light roast. Light roasts are hard to extract, so they need higher extraction efficiency; dark roasts extract easily, so they need less. But since everyone draws the roast-level lines differently, most roasters leave roast level off the bag entirely. In that case, use the flavor descriptions as your yardstick. Sort them into these types:

Floral and Fruity Notes: acid-driven fruits and flowers — citrus, berries, tropical fruits; white, purple, and yellow florals, and so on.

Sugary Sweetness: descriptions built on honey, sucrose, brown sugar, caramel, and other sweet tastes.

Spices and Nuts: descriptions dominated by roasted, bitter flavors — chocolate, nuts, spices.

Fermented Aromas: the special case — alcohol, dried fruits, and other flavors that only appear after fermentation.

If the label brims with floral and fruity notes or high sweetness like honey and sucrose, the beans are generally light to medium-light roasted. If weaker sweetness like brown sugar leads, with dark chocolate, nuts, or fruit in support, the beans are basically medium roast — and the secondary descriptions tell you whether to lean medium-light or medium-dark. If chocolate, nuts, and spices dominate, it's a dark roast.

Developing Brewing Parameters

With the roast level estimated, you can start building the recipe. Three parameters matter most: coffee-to-water ratio, grind size, and water temperature!

Coffee-to-Water Ratio: FrontStreet Coffee defaults to 1:15 — for dark or light roasts alike, it produces a pour-over of appropriate concentration. Want it stronger? Drop to 1:14. Want it gentler with more prominent flavors? Go 1:16.

Grind Size: Grind size is one of the most important parameters — it sets particle size and therefore how easily water extracts the coffee's compounds. If you have the equipment, use the #20 sieve calibration: light to medium-light roasts should pass at 75-80%, medium-dark roasts at 70-75%. No sieve? Skip it.

Water Temperature: As the extraction solvent, water temperature sets extraction efficiency — hotter water extracts more. Light roasts are denser and harder to extract, so they need higher temperatures: FrontStreet Coffee recommends 90°C~93°C. The fresher and coarser the light-roast dose, the higher the temperature within that range. For dark roasts, use 87°C~89°C — again, fresher and coarser calls for the higher end, and vice versa.

Beans with special processing methods are their own case. Most are light to medium-light roasts, but anaerobic processing makes their structure more porous, so water drains faster. They follow the light-roast method, but the grind can go slightly finer to tighten the gaps between grounds, extend the water's contact time, and secure a complete extraction.

FrontStreet Coffee Recommendation

Putting the framework to work? For the floral-fruity, light-roast end of the spectrum, FrontStreet Coffee's Yirgacheffe Guodingding is the ideal candidate: bright citrus and berry notes with white florals and a green-tea-like sweetness — gentle and welcoming rather than sharp, exactly the profile that rewards the 90-93°C, higher-extraction approach.

Want even more tropical fruit in that same light-roast lane? FrontStreet Coffee's Ethiopia Huakui (Flower Queen) shows strawberries, passion fruit, jackfruit, and lychee, with obvious sweetness and almost no bitterness — so juicy many drinkers call it "the coffee for people who don't like coffee."

And for the dark-roast camp — chocolate, nuts, spices on the label — FrontStreet Coffee's PWN Golden Mandheling from Indonesia is the classic: dark roasted, low acidity, thick and long on the palate with herbal, dark-chocolate depth and a faint earthiness, richly layered and friendly to the gentler 87-89°C parameters.
