The Roaster's Blog
November 15, 2025
When people talk about great coffee, they usually start with the beans: origin, processing, roast profile, and brew method. At Beanlytics Roasters, a Vancouver specialty roastery, those details matter a lot—but there is another variable that quietly decides whether your cup tastes flat or phenomenal: water.
For anyone searching for the best specialty coffee roasters in Vancouver, understanding water chemistry is one of the fastest ways to unlock better flavor at home, using the beans you already love. Beanlytics roasts for clarity, sweetness, and balance; the right water is what allows those characteristics to actually show up in your cup instead of getting muted or muddied.
Coffee is between 98–99% water. That means the water in your kettle is not just a neutral medium—it is the main ingredient in your drink. The mineral content, pH level, and total dissolved solids (TDS) in your brewing water determine how effectively flavorful compounds extract from the coffee grounds.
Extraction is a chemical process: hot water dissolves acids, sugars, oils, and aromatic compounds. If your water is poorly balanced, this process either stalls (leading to sour, thin coffee) or goes too far (bitter, chalky coffee). For premium coffee roasters in Vancouver like Beanlytics, water chemistry can account for up to 30% of the final perceived flavor, which is why it deserves as much attention as grind size and brew temperature.
Four primary minerals play leading roles in coffee extraction: magnesium, calcium, bicarbonate, and sodium. Each one changes the way your coffee tastes and feels.
Research in specialty coffee has shown that a roughly 2:1 ratio of magnesium to calcium often produces optimal extraction—magnesium lifts the high notes, while calcium fills in the body—creating a more balanced and complex cup.
To make water practical for everyday brewing, it helps to think in terms of a few measurable parameters: TDS, hardness, and alkalinity.
TDS measures the total concentration of minerals in your water (in ppm). It is one of the best quick indicators of whether your water is likely to under‑ or over‑extract coffee.
The Specialty Coffee Association recommends 75–250 ppm with an ideal target around 150 ppm, which aligns with what many leading roasters and water researchers use.
Hardness specifically measures calcium and magnesium, often expressed as ppm of calcium carbonate (CaCO₃). It is different from TDS, which includes all dissolved minerals.
Alkalinity measures how strongly your water resists changes in pH when acids (like coffee) are introduced. For flavor, alkalinity is often more important than pH itself.
Brewing water pH should generally sit around 7.0 (neutral), within a workable range of 6.5–7.5. Below 6.5, the water is too acidic; above 7.5, it can suppress acidity and nuance.
Beanlytics Roasters focuses on single‑origin, organic coffees roasted for clarity, sweetness, and balance. That means every roast profile is tuned so that, with good brewing water, you taste layered sweetness, distinct origin character, and a clean finish, rather than just generic “coffee flavor.”
With soft water (very low minerals), a Beanlytics Ethiopian can taste thin and sour, no matter how carefully you brew. With very hard water rich in bicarbonate, the same coffee can become heavy, bitter, and muddy, losing the citrus and floral notes the roaster worked hard to highlight. When you bring your water into the recommended ranges—TDS around 150 ppm, hardness 50–100 ppm, alkalinity around 40 ppm—the results are dramatic: more sweetness, more clarity, and more repeatability in every pour-over or espresso shot.
This is one of the reasons Beanlytics is quickly becoming part of the conversation around the best specialty coffee roasters in Vancouver. The focus is not only on sourcing and roasting, but also on helping you recreate café-quality cups at home through education on water chemistry and brew parameters.
You do not need a lab to start optimizing your brewing water. A few low-cost tools and techniques can make a huge difference.
Even small adjustments—like moving from 300 ppm tap water to a 150 ppm filtered and remineralized profile—can transform a cup from harsh and bitter to sweet and layered.
For home brewers who want a repeatable, café‑quality water profile, the guide in your attached PDF suggests a straightforward recipe:
This recipe lands close to 150 ppm TDS with an optimal balance of magnesium and calcium, giving you a sweet, structured extraction that works beautifully for modern light‑to‑medium roasts.
If you want a tangible way to taste the impact of water chemistry, experiment with one of Beanlytics’ offerings, such as Sumatrabyte – North Sumatra Ateng, wet‑hulled. This coffee showcases earthy sweetness, citrus brightness, and a gentle smoky depth that really come alive when brewed with optimized water.

Brew it once with untreated tap water and again with a targeted water profile. Pay attention to how the citrus lifts, how the sweetness rounds out, and how the finish cleans up when the minerals are in the right place.
Great coffee is never an accident. It is the result of thoughtful sourcing, skillful roasting, and intentional brewing. For a roastery like Beanlytics Roasters in Vancouver, water chemistry is part of that craft. It is the bridge between what the roaster designs in the cupping lab and what you experience in your mug at home.
If you are exploring premium coffee roasters in Vancouver and want to get the most out of every bag you buy, treating your brewing water as seriously as your beans is one of the smartest upgrades you can make. With a basic understanding of minerals, TDS, hardness, and alkalinity, you can turn “pretty good” coffee into something truly exceptional—cup after cup.
