Can you make coffee with whole beans?

article image for What’s Wrong with Buying Ground Coffee?Every time we utilize ground coffee which will make our beloved cup Java. Yet have you ever stopped and wondered why we use surface coffee in the place of just whole beans? Or the reason why how big is the routine matters? Or the reason why some individuals have a look at you with complete disbelief once you inform them that you apply pre-ground coffee?

Well, we of course do countless wondering. So, hang in there and find out the responses to all these concerns.

The reason we Grind Coffee?

The basic goal of making coffee is to get what’s sealed inside the bean (namely, the delicious flavor elements and oils) out from the bean. The initial strategy included boiling the entire roasted beans in hot water while agitating all of them. With a few determination and a lot of time you’d in the course of time get a bitter, high-caffeine, coffee option.

Fortunately for us our coffee forefathers sooner or later came up with a more efficient approach to draw out the treats from the coffee! By grinding the espresso beans you help the liquid to draw out efficiently the solubles which can be responsible for the style and aroma in coffee.

Allow me to explain the reasoning behind this.

The Effective Removal of Solubles

Invest the a whole bean and slashed it in two you’ll increase the complete surface associated with the bean. As a result the extraction efficiency is greatly increased. Why? Because there’s even more surface for the heated water to act upon and where to draw out the flavor elements.

Now just take these two halves and cut all of them into halves once again. Do you know what, you’ve simply further increased the general surface area and therefore aided over the extraction performance much more. Ultimately you’ll end up getting the ideal grind dimensions for the preferred brewing strategy.

The benefit of all this work “cutting” is the fact that the extraction efficiency dramatically significantly reduces the brewing time. But that’s maybe not the only reason we grind coffee.

Smaller routine particles lead to a far more full removal

Small particle dimensions makes the distance from its center shorter. This permits not only for a more efficient removal, but in addition for a more complete extraction of soluble tastes contained within the particle.

Why Should You Perhaps Not Get Pre-Ground Coffee

A roasted entire coffee bean is a lovely, defensive package that keeps the coffee natural oils exactly where we wish all of them, particularly, inside the bean. So long as you don’t mess with the beans the flavor components, that are really delicate, volatile and water-soluble substances, will undoubtedly be safe. However, break the defensive layer and all sorts of wagers tend to be down.

Exposing the four great reasoned explanations why NOT to buy pre-ground coffee.

1) Contamination

Coffee essential oils are delicate, helping to make all of them a straightforward prey of contamination. Whatever smells are around ground coffee will taint it in many ways that won't play a role in your coffee tasting experience.

2) Air

The cells within the roasted coffee bean contain about 1, 000 different volatile aromas and flavors. When ground the volatile aromas are instantly released in addition they respond with oxygen in the air (oxidation). After fifteen minutes ground coffee loses about 60per cent of their aroma.

3) Moisture

Coffee oils are water-soluble. That’s the best thing or we’d have actually an extremely experienced time looking to get the essential oils out of the bean. This particular fact however presents a great problem for surface coffee. When ground coffee is exposed to dampness into the environment it immediately begins to dilute the essential oils.

4) Co2 Depletion

Increased surface permits for better skin tightening and (CO2) . During roasting process countless CO2 is established. Because the bean is porous, some of it's lost during cooling procedure. Most of it, but is retained inside the cells of this coffee bean. This CO2 plays a crucial role because this is the main way for obtaining the essential coffee essential oils into the coffee after they are circulated.

The Problem is your enhanced surface produced after grinding licenses for higher CO2 gas liberation. In reality within one minute of grinding 80per cent of this gasoline is circulated to the environment. Wait too much time after grinding the coffee and you’ll trade your Ferrari for a spin cart with underinflated tires.

The perfect solution is: constantly grind your coffee freshly prior to brewing. Follow this rule and you’re one step closer to paradise in a cup.

Three Facets that will Influence the Grind

There are several elements that can influence just how roasted coffee beans behave when you grind them. Let’s check three important people here.

1) Roast Degree

In general the greater light the roast, the more pliable and tenacious the bean. Therefore a lightly roasted coffee will probably be much more flexible and tenacious than a darker roasted coffee. The explanation for this really is your much more you roast a coffee, the greater moisture is lost throughout the roasting process, which makes dark roasted beans more brittle.

Process Method

The strategy used to procedure coffee affects how the beans at the same roast level grind. Coffees processed utilizing the dried out procedure grind in a different way than coffees utilising the wet-process.

New Crop vs. Last Crop

Whenever coffee ended up being harvested makes a difference to exactly how it's going to work. Often coffee can be obtained for roasting three to 6 months after harvest. The aim is to roast the coffee asap, since green coffee gets woodier and woodier with each month that goes on. Understandably this can be one of many aspects that after that affects the way the coffee ultimately roasts. Coffees from brand new crop coffees produce less good dirt particles than from previous crop coffees.


Coffees cultivated at greater height (about 1, 800 ft and overhead) grind in a different way than coffees grown the lowest height (mainly Robusta). The cause of this can be that higher the altitude, the slower-maturing the beans, and therefor the harder and denser its compound.

Arabica vs. Robusta

The difference in cell construction between beans in addition is important within the few particles produced after milling.

3) Air Quenching vs. Water Quenching

As soon as the beans emerge from the roaster they need to be cooled down instantly to avoid over roasting. This is called “quenching” inside coffee industry.

Some roasters add liquid to the atmosphere stream that cools the beans to start the soothing procedure. But “water quenching” (if done improperly and indiscreetly) harms the surface of the roasted beans and certainly will include liquid lost through the roasting procedure back into the beans. On the other hand, air-quenched coffee is cooled by pulling environment through beans as they are stirred; no water can be used during air-cooling.

The take-way let me reveal your strategy that is used to cool roasted coffee can impact the beans in manners that can in the end lead to inconsistent grind particles.

Coffee Grind Chart

One of the many advantages of grinding a coffee usually you’ll have the ability to accurately “calibrate” the routine based your preferred brewing method and types of coffee. More over, as soon as you’ve discovered that which works to you system of brewing you can easily and regularly replicate it. You certainly will no more be susceptible to some common “one size suits all” routine.

Grind Size


Extra Coarse Reminds myself of tiny pebbles.
Coarse Chunky, distinct particles, like coarse sea salt.
Moderate More the surface of coarse sand.
