Brew, store, and troubleshoot coffee and tea, with practical care for your brewing equipment.
Search this topicCombine 100 grams of coarse coffee with 500 grams of water in a clean, covered food-safe container. Stir to wet the grounds and steep in the refrigerator for about 12 hours as a starting recipe. Filter into a clean covered container, refrigerate, and dilute portions to taste before drinking.
No. Cold brew extracts coffee with cool water over a longer period. Iced coffee is usually brewed hot and then chilled or poured over ice. Either can be refreshing, but changing the extraction method changes flavor. A cold-brew concentrate also needs dilution; ready-to-drink iced coffee generally does not.
Yes. Add coarse coffee and cool water using your cold-brew recipe, stir, cover, and keep the plunger raised during the refrigerated steep. Lower it gently when brewing finishes, then pour the coffee into a clean covered container. Strain again if you want less sediment, and wash the press afterward.

Stir the package's recommended amount into hot water in a heat-safe mug. A general starting point is one teaspoon per 6 fluid ounces. Instant coffee is already brewed and dried, so you do not need to steep or filter it. Adjust the amount of granules for your preferred strength.
Dissolve the instant coffee in a small amount of hot water first, then add cold water or milk and ice to reach your preferred strength. Some products dissolve directly in cold water; follow their label. Account for melting ice so you do not dilute an already weak drink.
Ground coffee is roasted bean material that still needs brewing and separation from the drink. Instant coffee is brewed coffee that has been dehydrated, so its soluble granules dissolve again. Grinding beans very finely does not turn them into instant coffee; use a suitable brewer or buy a soluble product.
It means the finished espresso weighs twice the dry coffee dose. For example, 18 grams of grounds produces a target of 36 grams in the cup. Weigh the liquid, not just its volume, because crema changes volume. It is a starting recipe to adjust, not a guarantee of flavor.

Use a dose that suits the basket, distribute the grounds evenly, and tamp into a level, compact puck. Clear loose grounds from the rim, fit the portafilter, and start the shot according to your machine's instructions. An uneven bed encourages water to find easier paths through the coffee.
Once it is safe to remove under your machine's instructions, discard the used puck, rinse the basket, and clean and dry the handle assembly. Clear residual grounds from the group head as directed. Routine cleaning prevents old grounds and oils from carrying into the next shot.
The first small pour wets the grounds and lets trapped gas escape before the main pour. A starting bloom uses about twice the dry coffee's weight in water, followed by roughly 30–45 seconds of waiting. Wet the bed evenly; vigorous bubbling is not a requirement for every roast and age.
A starting ratio is 1 gram of coffee to 15 grams of water, such as 20 grams and 300 grams. That is within the National Coffee Association's range. Use a scale, include bloom water in the total, and adjust gradually rather than changing coffee, grind, and water together.
After blooming, pour slowly in controlled circles or a gentle back-and-forth pattern to wet the bed evenly. Keep the brewer stable and avoid overflowing the filter. Use the same pouring pattern between test brews so changes in taste are easier to connect to grind, dose, or temperature.
With a consistent dose and target yield, a very fast, sour shot often needs a finer grind. Change it a little and test again. Also check fresh beans, adequate machine temperature, and even puck preparation. Taste and flow together are more useful than judging a shot only by its color.
A grind that is too fine can restrict flow and contribute to a harsh, slow extraction. Keep the dose and target yield steady, move slightly coarser, and retest. Check for an overfilled or dirty basket too. Do not keep changing every variable at once; write down what improves the taste.
Spread the grounds evenly before tamping, break up troublesome clumps using a suitable tool, and tamp level. Channeling means water is finding preferential paths instead of moving evenly through the bed. Improve this preparation before assuming a new grinder is necessary, and compare shots with the same dose.
Bialetti recommends washing its parts in hot water and discarding the first three brews. Follow the enclosed instructions for your exact model and let it cool between handling steps. Grip the body to unscrew it rather than using the handle as a lever, which can break the handle.
Unplug it before removing parts or reaching inside. Follow the model's procedure to remove the accessible burr and brush dry grounds from the chamber and chute. Wash only the removable parts approved for washing, and dry them fully before reassembly. Keep liquid out of the motor and grinding mechanism.
Stop and unplug it; do not keep grinding into a possible blockage. Check the grounds bin and the accessible exit chute using the model's cleaning instructions. Oily coffee and very fine grounds can compact there. Clear and reassemble properly before testing; seek support if the obstruction or abnormal noise remains.
They can. Oils left by darker roasts make grounds stick inside the hopper and chute, increasing residue and clogging risk. Inspect these areas regularly and clean more often when buildup appears. Baratza suggests routine cleaning around every four to six weeks, with actual use and bean condition guiding adjustments.
They are often chaff, the thin silverskin remaining from the coffee bean. Lighter roasts tend to retain more, so pale flakes do not automatically mean your grinder is failing. Normal chaff is lightweight and papery. Actual foreign debris, mold, or an unfamiliar contaminant deserves separate inspection rather than that assumption.
Fine particles and heavy agitation can clog the paper. Try a slightly coarser grind or a gentler pour, changing one thing at a time. Check that the filter fits correctly; paper type also affects flow. Judge the resulting taste as well as the timer instead of chasing one universal brew time.
Keep the recipe steady and try a slightly finer grind. If appropriate for your recipe, longer pauses between pours can also increase contact time. Record the change and taste again. A quick drawdown alone is not a fault: a fast brew that tastes balanced does not need automatic correction.
Put the thicker, three-layer side against the pouring spout, with the single layer on the opposite side. The extra paper supports the filter so it is less likely to collapse into the spout. That channel must remain open for air to escape while coffee drains into the lower chamber.
No. The three-cup brewer and FUNNEX use the smaller half-moon FP-2 or FP-2N filters. Larger standard brewers use the appropriate full-size CHEMEX filters. Check the model and filter package rather than buying by appearance; a poorly fitting filter can interfere with brewing or safe removal of wet grounds.
