How to Make Pour Over Coffee: The Complete Guide
Quick Answer
Pour over coffee is brewed by slowly pouring hot water over ground coffee in a filter, allowing gravity to pull it through. The result is a clean, bright cup with precise flavor control. Pour over does not change a coffee's underlying pH — acidity is set by roasting. For a genuinely low acid pour over, start with a coffee verified above pH 5.5, like Puroast (pH 5.82, LACCSA verified).

Pour over coffee has become the preferred method for coffee enthusiasts who want maximum control over flavor. By manually controlling the pour rate, water temperature, and bloom, you can highlight different flavor notes in any coffee. But there's one thing pour over cannot do: change the underlying acidity of the coffee. That's set by the roasting process long before the water touches the grounds.

What Is Pour Over Coffee?
Pour over is a manual brew method where hot water is poured over coffee grounds in a filter cone — typically a Hario V60, Chemex, or Kalita Wave. The water passes through the grounds by gravity, extracting flavor compounds as it flows through the filter into a vessel below. The brewer controls the water temperature, pour speed, and total brew time manually.
Unlike a French press or espresso machine, pour over uses a paper or metal filter that removes most of the coffee oils (diterpenes). This produces a cleaner, brighter cup with more defined flavor clarity. The tradeoff: some beneficial polyphenols are removed along with the oils.
Step-by-Step Pour Over Brewing Guide
Step 1 — Grind: Use a medium-coarse grind — slightly coarser than drip, finer than French press. Consistency matters more than size. A burr grinder produces far more even particle size than a blade grinder, which leads to uneven extraction and more bitterness.
Step 2 — Rinse the filter: Place your paper filter in the dripper and rinse with hot water before adding grounds. This removes paper taste and preheats the vessel. Discard the rinse water before adding your grounds.
Step 3 — Bloom: Add your grounds (roughly 1g per 15ml of water). Pour twice the weight of water over the grounds — if you have 20g of coffee, pour 40ml of water. Wait 30 seconds. This releases CO2 from the grounds (degassing), allowing the subsequent pour to extract evenly. Skipping the bloom leads to channeling and uneven extraction.
Step 4 — Pour: Pour in slow, steady concentric circles starting from the center and working outward. Avoid pouring directly on the filter walls. Pour in two to three additional pours, allowing the water to draw down slightly between each one. Total brew time should be 3–4 minutes.
Step 5 — Water Temperature: 195–205°F (90–96°C). Water above 205°F extracts too aggressively — pulling bitter compounds faster. Below 195°F under-extracts, leaving sweetness in the grounds and making any residual acidity more prominent. Research in the Journal of Agricultural and Food Chemistry (Moon, Yoo & Shibamoto, 2009) confirmed that water temperature directly controls the extraction rate of chlorogenic and quinic acids.

Frequently Asked Questions
Does pour over coffee reduce acidity?
No — pour over does not reduce a coffee's underlying pH. Acidity is set by roasting chemistry. The paper filter in pour over removes some oils and bitter compounds, which can reduce perceived bitterness, but the base pH of the brewed coffee is unchanged. Only starting with a lower acid coffee can reduce actual acidity.
What grind size is best for pour over?
Medium-coarse — slightly finer than French press, slightly coarser than drip. Too fine causes over-extraction and bitterness. Too coarse causes under-extraction and sourness. A consistent burr grinder is strongly recommended over a blade grinder for even particle size and balanced extraction.
What water temperature should I use for pour over?
195–205°F (90–96°C). This range extracts flavor compounds fully without over-extracting bitter or acidic compounds. If you don't have a temperature-controlled kettle, bring water to a boil and let it rest 30–45 seconds before pouring.
Is pour over better for acid reflux than drip coffee?
Not inherently — the underlying pH is the same for both methods if you use the same coffee. Pour over's paper filter removes more oils, which some find easier on the stomach. But the most effective change for acid reflux is switching to a coffee verified above pH 5.5, like Puroast (pH 5.82, LACCSA verified), regardless of brew method.
What is the bloom step in pour over coffee?
The bloom is an initial small pour (twice the coffee weight in water) that saturates the grounds and releases trapped CO2 gas. Fresh coffee releases more CO2, which creates bubbling during the bloom. Allowing 30 seconds for degassing before continuing ensures even water distribution and balanced extraction throughout the brew.
The Only Coffee Verified Low-Acid by Independent Science
Great pour over technique starts with great coffee. Puroast is LACCSA verified at pH 5.82 — the only commercially available coffee above the 5.5 threshold. Your technique does the rest.
