Fresh coffee beans

If you ask a famous chef, how to cook delicious food? I believe that there must be an item of "fresh ingredients" in his answer. Because as long as it's good.

The cook will not use stale, out-of-date materials to cook his specialty dishes.

Coffee, so the first step in a good cup of coffee is fresh coffee beans.

What are fresh coffee beans?

In fact, coffee beans begin to lose their freshness after baking, and as the time spent in contact with the air increases, the beautiful substances in coffee beans gradually decrease, especially those that have been ground.

Why do ground coffee beans have a shelf life of only 5-10 minutes?

The main reason is that the surface area of ground coffee beans becomes very large, so the rate of oxidation increases several times, and it will not be long before the coffee beans deteriorate because of oxidation, let alone want to make good coffee.

Different shelf life of coffee beans:

Raw beans of unroasted coffee for 1-2 years

Roasted coffee beans 30-45 days / roasted coffee beans (for cooking Espresso) about 3 weeks

Ground coffee beans for 5-10 minutes

Coffee beans must be preserved in a good environment in order to have the above life.

Therefore, it is strongly recommended that any coffee must be ground before brewing, and only one cup at a time!

From the point of view of fresh grinding and cooking, buying ground coffee beans is obviously the most difficult way to keep them fresh.

The most common situation is... Go to the coffee shop and buy a pound of coffee beans and ask the shop to grind them instead.

Think about it. How long will it take to finish a pound of coffee beans? A week? Or more than two weeks?

How can you expect to brew good coffee with this kind of coffee beans that lose all their freshness?

Second, suitable grinding particles

Coffee beans must be ground before brewing because of their insistence on freshness.

So the bean grinder has become a necessary tool.

In the pursuit of good coffee

A qualified bean grinder is an absolutely necessary equipment.

A very important idea: a good bean grinder is more important than a good coffee maker.

3. Good water quality

How important is water? Just look at more than 95% of the water in a cup of coffee. What kind of water is suitable for brewing coffee? Is the cleaner the water the better?

Actually, not really. Like making tea, tea made from too clean water will not taste better than that from mountain springs.

By the same token, if the water contains the right amount of minerals, it can enrich the taste of coffee.

4. Proper water temperature

In fact, the water temperature suitable for brewing coffee is about 85 to 95 degrees Celsius, and the brewing temperature depends on the degree of roasting of coffee beans.

5. Appropriate extraction methods

Soaking method:

French filter pressure and Turkish coffee are all soaked in hot water.

Finally, the coffee grounds were separated to get stronger coffee.

Soak the hot water and coffee powder in the cylinder for four to seven minutes, then press the coffee powder to the bottom by a piston filter, and the top coffee can be poured out to drink.

This "complete immersion method" is considered by many experts to be an ideal household method for making coffee.

Decocting method:

Just like in many films, foreigners put pot-shaped coffee pots down in the morning to make coffee, using the stove to slowly heat the coffee and the convection extraction in the water to take out the coffee, which is mostly used in American coffee.

"cowboy coffee" is to boil the coffee powder and water directly in the pot and drink it.

Trickle filtration method:

Put the coffee powder in a permeable container (pot) and put filter paper to prevent the powder from seeping into the extracted coffee liquid.

Use hot water to pour into the coffee, extract the smell of the ground coffee powder into the water, and let the coffee flow from up to down to complete the extraction. The extraction time is about 2 minutes.

In addition, ice droplets also belong to this way of dripping filtration.

Siphon method:

Its principle is similar to the immersion method, but the difference is that there is still a heat source in the extraction process.

Siphon Syphon is to use the siphon principle to push the hot water from the lower pot to the upper pot to extract coffee.

After completing the extraction process, put the heat source of the next pot to boil the water, and the hot water will flow back to the next pot because of the cooling of the hot air.

Pressure method:

The obvious examples are Espresso semantic condensation and Aeropress Philharmonic pressure.

The former is made of 80 Murray 96 degrees Celsius hot water at 8 Murray 9 atmospheric pressure through compacted coffee pressed powder.

The latter is first stirred and extracted in hot water, and finally the coffee is extracted by freehand pressure.
