What Happens When You Brew Coffee…
When you are brewing coffee, hot water acts as a solvent, washing the soluble solids out of the coffee grinds and into the brew. If you dissolve table salt in water, you have a soluble solid. Soluble solids are bonded with the water molecules, and will not separate over time. Brew methods that use paper filters have only the soluble solids in the cup. Some brew methods allow insoluble solids to enter the brew, like A simple coffee brewer also called a Press Pot: grounds and hot water are added to a carafe, allowed to sit for several minutes, and then a filter is pushed down to hold the grounds More, A small coffee beverage, about 20 ml, prepared on an espresso machine where pressurized hot water extracted through compressed coffee.: In its most stripped-down, basic form, this is a working definition for espresso: A small More or A strong preparation of coffee, finely ground, and often prepared in an Ibrik over a heat source like a gas stove. Traditionally it was placed in hot sands and the vessel itself would hold 1 More. Insoluble solids will settle out of the brew over time if you don’t disturb the liquid. Hence your mug of French Press coffee might taste gritty nearing the end, and there will be muddy residue in the bottom of the cup. Suspended solids add a sense of Associated with and sensed by mouthfeel, body is sense of weight and thickness of the brew, caused by the percentage of soluble solids in the cup, including all organic compounds that are extracted from brewing More to the cup, but can also add Bitterness is one of 5 basic tastes: Sour, Sweet, Salty, Bitter and Umami (savory flavors). There are many types of bitterness, hence not one avenue to tracking down its source. Bitterness as a positive quality More tastes..
The 5 main factors that affect your brew:
- Coffee-to-water ratio. Most people find that when 20% of soluble solids are extracted from the coffee grounds, the brew has the best flavors. Too much Refers to the process of infusing coffee with hot water. Hot water releases or "extracts" the flavor from the roasted, ground coffee. The term is used mostly with espresso, adding pressure to the mix as More (too fine grind, too long brew time, too hot water, too much ground coffee) and the brew tastes bitter. On the other hand, under-extraction results in a thin, weak, Sour is one of four basic sapid (in the mouth) tastes: Sour, Sweet, Salty, Bitter (and possibly a 5th called Umami which indicates savory flavors). In coffee, sourness in moderate amounts of favorable, although the More cup. Simply using more coffee grounds doesn’t correct under-extraction. It is a good idea to weigh your coffee or use an SCAA coffee scoop or a measuring device that you know will hold 10 grams of coffee. It is also a good idea, at least initially, to weigh or measure your water as well.
- Coffee particle size. A finer grind means more surface area of the bean is exposed to the water. For a brew method that uses a longer dwell time such as French Press, a coarser grind is necessary. An even grind of any size is ideal, follow the directions on your grinder, it may take some experimentation to find the best grind for your brew method here is an illustration (photo of different grinds)
- The Water Temperature. The ideal water temperature is 195-205 f, since water is a better solvent at near-boiling temperature. This is why it is always better to brew a full batch on an auto-drip machine, since they are built to get a full batch of water up to the proper temperature.
- Contact time. How long the water and coffee are in contact with each other. See our brewing instructions below.
- Agitation. Stirring the coffee-water infusion increases the extraction rate of soluble solids. Keep in mind that pouring water over the grounds causes agitation. In immersion brew methods it is important to agitate (stir) the brew again during the dwell time.
- Heat Retention. Don’t let coffee sit on a hot plate or in a French Press transfer to a thermal carafe to avoid overcooking and over-extraction.
Other factors that have a major impact are:
– The quality of the water. Bad tasting water makes for bad tasting coffee. Also, do not use distilled water. You need some mineral content to properly extract the good stuff from your coffee. The absence of some minerals can lead to very sharp and bitter tastes.
– The quality of the coffee you are using, obviously, and also the roast level. Speaking in broad terms, some roast levels perform better in different brew methods. Lighter roasts can taste aggressively bright in immersion brewers and some pour over methods don’t really showcase the caramelized Sweetness is an important positive quality in fine coffees, and is one of five basic tastes: Sour, Sweet, Salty, Bitter, Savory (Umami). In coffee, sweetness is a highly desirable quality, and the green bean has More in darker roasts. Of course, brew ratios can address some of these issues.
–The cleanliness of the brewing equipment. Old sediments easily make for rancid flavors in the cup. A good rule of thumb is: if you smell an odor from your equipment, clean it. If you can’t remember the last time you cleaned your brewer, clean it.
The ideal brewing practice is:
- Grind immediately before you brew.
- Adjust grind to brewing method and use a grinder that produces a consistent grind.
- Use fresh, clean water. If your water does not taste good, your coffee won’t either.
- Pre-rinse your paper filter to remove any loose paper fibers that can end up in your brew and make your coffee taste papery.
- Heat retention is also an issue in many manual-brewing devices, Pre-heat your filter-cones and presses.
- Don’t let it sit. Coffee is only fresh for about 10 minutes. Try to make the right amount of coffee so you are drinking fresh Brewed Coffee refers to all coffee preparations produced by adding non-pressurized water to coffee grounds. Contrasted with espresso coffee, which is produced under pressure, brewed coffee is primarily an extraction, and contains a lower amount More more often.
Here are some ideal coffee/water/time ratios for different brewing methods:

*Tip for Vacuum Brew: Infusion time measured once water is up in the coffee. There is a range of techniques – from adding hot water to the bottom bowl to letting the water rise to the top and then adding the coffee. So you may want to check out a Hibrido de Timor abbreviated HdT is the interspecies hybrid of C. Arabica and C. Canephora (Robusta) that was found in Timor Leste in the 1940s. It has been the bases of plant breeding for disease More of techniques and find the one that works for you.
*Tip for Technivorm: We close the drip stop switch on the brew basket (KBT-741 & KBTS models), wait for the brew basket to fill, stir and then let it flow.
*Tip for Frenh Press: Plunge after infusion time, then pour slowly. After plunging I actually like to wait 2-4 minutes more, for fines to further settle. Try it!
Water temperature for all brewing is 195 to 205 degrees. Typically this means water just off the boil. We greatly prefer 205, since the brew device itself usually becomes a heat sink.
On weighing ground coffee: It is much more accurate to measure roasted coffee by weight, since dark roasted coffee takes up more room than light roast. A “standard coffee scoop” (which in reality can vary widely) ought to be equal to two level Tbsps, which is be 8 to 9 grams of dark roast, or 10 to 11 grams of light roast coffee.
