1. How much caffeine is in a bag of coffee for hanging ears
The content of caffeine in a bag of coffee for hanging ears is between 150-300mg. So what factors will affect the caffeine content of hanging ear coffee?
A bean seed, Arabica is less than robusta. The ground coffee powder in the hanging ear bag is more fine than the coarse one. Water temperature, 88-92 degrees of water is more likely to precipitate caffeine. The amount of water, 10g of hanging ears as an example, is recommended to be 150ml for brewing. If there is too much water, more caffeine will be precipitated. The flow rate of the water, the slow injection of water, the precipitation of caffeine is more thorough. If you want different caffeine in the same bag of coffee with hanging ears, here are two suggestions:
Ways to get more caffeine: After hanging the ears, brew with 92-degree water, and fill it with water for the first time Increase the simmering time to 2 minutes. Follow-up water injection is carried out, and the total water volume is controlled at about 160ml.
Less caffeine: After the ear is hung, brew it with 88-degree water. The time of the first injection depends on whether it is dripped clean, and then the subsequent injections, the total amount of water. Control at about 150ml.
2. How to choose ear-mounted coffee
1. Coffee origin information
This purchase The angle is very important! It directly determines whether the coffee is good or not, and whether it has the entry requirements for specialty coffee. The origin of this coffee bean is often the most easily overlooked. For most of the commercial hanging ear coffee, the definition of coffee product is between vague and ambiguous, and it is rarely proved that the label is clear. Yes, so we should choose the hanging ear coffee that indicates the specific estate or cooperative, so that the quality can be guaranteed.
2. Freshness of coffee beans
Hanging ear coffee is a portable coffee that is ground and sealed in a filter bag. Whether the coffee beans are The season of the year determines the taste of hanging ear coffee, which can be said to be the soul and essence of a cup of hanging ear coffee. Therefore, only by ensuring the freshness of the coffee beans can we understand the deeper flavor of coffee.
3. The degree of roasting of coffee beans
We all know that after coffee cherries are picked, they need to be “processed” to become green coffee beans. Transported to various roasting plants and then roasted. Roasting will select the most suitable roasting method according to the state, origin, and moisture content of green coffee beans. Correspondingly, light roasting can retain more fruit acid, starch, and sweet substances, so light roasted coffee beans generally show more “sour”, and the sweetness will be relatively obvious. The middle-roasted coffee beans already have caramel and the caramel aroma of Maillard reaction, so the middle-roasted coffee beans basically retain the flavor, but they are neither sour nor too bitter. In the final deep roasting, because of the high roasting degree and the continuous high temperature in the baking oven, the flavor substances are basically emitted more, so almost no flavor substances are contained. Also followed, the performance is more bitter.
4. Packaging of hanging ear coffee
Many commercial hanging ear coffees use the gimmick of “nitrogen” filling. Nitrogen filling is good for fried coffee. Food has an absolute effect, preventing the oil in food from oxidizing and deteriorating after contact with oxygen. But for hanging ear coffee, nitrogen filling makes little sense. First of all, nitrogen is an inert gas, and 78% of the air is nitrogen. Secondly, after the coffee beans are ground into powder, because the overall surface area is greatly increased, the gas in the coffee powder will be mixed with the surrounding gas. At the same time, the coffee is also dissolving alcohols and esters. The final packaging must be absolutely airtight, otherwise it will make the flavor substances fast.
5. Reliable brand
For coffee, this is actually equivalent to finding a professional coffee bean roaster, I believe that professional things are left to professional people. An excellent barista will ensure that the coffee beans have the most suitable grinding degree and accurately reproduce the hand-brewed coffee according to the state of the coffee beans themselves and their familiarity with the coffee roasting equipment they are used to. As consumers, we only need to choose a reliable brand with confidence.
