According to statistics, one of the most popular hot drinks today is coffee. Most coffee drinkers know that the secret to a “good cup” is freshly ground coffee, and therefore prefer to grind their own beans. However, having a coffee grinder in their arsenal of kitchen appliances, not everyone knows how to grind coffee in it correctly. Let’s analyze this issue in more detail.
Despite the huge variety of coffee blends, on sale you can often find the two most popular varieties – Arabica and Robusta.
- Arabica valued for its rich aroma, which is given by grains rich in acids, essential oils and sugar.
- Robusta slightly faded against the background of Arabica, but has a high concentration of caffeine with a characteristic bitterness.
When choosing coffee beans, first of all, you need to pay attention to the packaging. The bag must be airtight, with well-sealed corners and have an outlet valve. It may look like a round embossed impression with a hole. The special design of the valve ensures the release of carbon dioxide and protection from the ingress of oxygen, which can literally “age” the coffee and make the drink rancid.
Simple criteria for evaluating grain in a package:
- the aroma should be bright and “rich”;
- uniformity of roasting (best achieved by processing with a stream of hot air);
- all grains must be the same size and color;
- absence of visible defects (beaten or split fragments).
Important! The period of roasting and packaging should not exceed 4 months, otherwise there is a risk of getting a drink with poor taste.
Types of grinding
It is important to determine the grind time and grind size for different coffee brewing methods. A professional barista characterizes the grinding of grains in 4 basic options.
- Ultrafine or coffee dust, means maximum friction for a light powder that leaves a bright mark on the fingers. This fraction is suitable only for the classic brewing of oriental coffee in Turks. The best drink will be in a copper container with an inner layer of silver that will retain all the flavors. A budget coffee grinder grinds finely for about 20 seconds. If the knives are not sharp enough, it is better to stop the device for half a minute so as not to overheat the grains and repeat the cycle for another 10 seconds.
- Fine grinding can be obtained in approximately 15 seconds. It is designed for an espresso machine or a geyser coffee maker with a fine filter. To gauge the density of a coffee concentrate, it’s best to drink a finished small cup as soon as it’s ready, as it will be at an ideal temperature of 75-80 degrees at that point.
- Medium grind designed for brewing in an Aeropress (the new method, which has existed for about 10 years, means manual smooth squeezing of powder diluted with boiling water in a special metal cylinder) or pour over (using a funnel with grooves and a filter, through which the powder with boiling water slowly flows into the lower container).
- coarse grinding used for preliminary tasting or when brewing coffee through a French press (a glass teapot with a stem, which can be slowly lowered after 4-5 minutes after brewing with boiling water of the powder and a ready-made drink is obtained).
It is important to remember that when manually brewing coffee without an open flame, all dishes should be rinsed with boiling water. Also, the aroma will be revealed better if the drink is poured into a warm cup.
Some coffee lovers warm up the beans a little before grinding so that the aroma opens up better.
Varieties of coffee grinders
The taste of coffee is born in a coffee grinder, so the choice of the kitchen appliance we are considering should be approached with particular seriousness. Present on the market three types coffee grinders that differ in appearance and control method:
- knife (rotary) type;
The most common models are rotary type devices, coffee is ground using rotary blades that rotate at high speed, grinding aromatic beans. In this case, the adjustment of the degree of grinding depends on the duration of the action of the rotary knives. That is, the more their rotation, the finer the grinding. The main disadvantage of this method is the inhomogeneity of grinding. The capacity of cutlery is usually no more than 120 g.
In grinders conical or cylindrical millstones are used. They function akin to a mill – the grains, falling between the millstones, are crushed and ground into small particles. The degree of grinding is independently adjustable, and depends on the distance between the millstones. In this case, the degree of grinding is quite uniform. The capacity of these models is up to 300 g of coffee beans. Among all coffee grinders, this type of device is the most popular.
The main advantage that distinguishes a burr coffee grinder from a rotary one is the availability of a container for finished ground coffee.
Manual coffee grinder is a great way to get the right amount of fresh, finely ground coffee. The manual version of the device consists of two millstones, one of which is attached to the bottom, and the second rotates due to the handle. The advantage of a coffee grinder is that you can’t “burn” coffee in it. Pour the grains, turn the handle and in 15-20 minutes you get ready-made coffee powder, which is poured into a specially designed container.
Advice. Do not use the grinder to grind other foods, so as not to mix in additional odors.
Instructions for grinding beans
How do you properly grind coffee in an electric coffee grinder? To do this, you must follow the following procedure:
- Prepare coffee grinder.
- Pour grains into it.
- Turn on the device.
- Record the time: 10 seconds – coarse grinding, 13 seconds – medium; 15-20 seconds – fine and more than 30 seconds – ultra-thin.
- Open the lid and pour out the ground grains.
Advice! When using a coffee grinder with a small volume of grains, you can slightly shake the device so that the knives grind the raw material evenly.
If there is no coffee grinder
If grinding coffee beans and preparing an aromatic drink is rare, then a specialized coffee grinder may not be in the kitchen. For one-time cooking, you can use improvised means or other kitchen helpers.
- Electric meat grinder with spice attachment (in case of uneven grinding, you can repeat the process twice).
- Blender with lid and sturdy blades (if the mill is not provided in the kit), but the body will need to be rotated or shaken for uniform grinding.
- Normal stone mortar or hand grinder for spicesafter thoroughly washing the instruments so that there are no foreign odors that can spoil the taste of the drink.
- Hammer or rolling pin on a kitchen boardfilling the grains in a disposable bag with a lock.
Such methods are suitable as emergency, but it is almost impossible to regulate the quality of grinding without a coffee grinder. Therefore, the grains will be ground unevenly.
Terms and rules for storing ground coffee
In order to always be able to brew high-quality coffee, it is important to adhere to the rules for purchasing roasted beans. If it is possible to order raw materials for a two-three day roasting period in a sealed bag with a lock, then such grains can be safely ground and boiled within the next month. The condition will retain maximum aroma and will not oxidize under the influence of oxygen with a short opening time.
Important! Gourmets recommend not to grind the beans “in reserve”, because when the beans are destroyed during grinding, the coffee oil evaporates very quickly, even if the storage container has a tight rubberized lid.
The right decision would be to do a full cycle of making a drink, which will begin with grinding and end with brewing.
The coffee grinder is a device for true connoisseurs of the “energy drink” and owners of free time. Freshly ground coffee has a surprisingly rich taste and unsurpassed aroma. To understand how to properly grind fragrant beans in your machine, you just need to know its type and choose the right degree of grinding that matches your coffee brewing method. Given these nuances, you will not encounter problems in the process of brewing your favorite hot drink.
