Front Street-Fresh Coffee Beans, Brewing Method Introduction

It varies according to ambient temperature, humidity, packaging method and storage method. In Taiwan's environmental conditions, coffee beans are stored in one-way breathable bags and placed at room temperature,"within two weeks after roasting" are considered fresh coffee beans.

Judgment 1. Store management mode

1. Mark "baking date": Note that the baking date is marked on the purchase package, not the shelf life.

Second, in addition to the order baking, but also provide free choice of baking degree: roasted coffee begins to decline, taste. They advertise order baking, but they don't let you choose the baking degree. It is possible that a batch of baked goods are placed, and orders are slowly shipped in the way of operation.

Judge 2, judge from coffee beans

Smell: Fresh beans have only aroma, smell of fuel consumption, it must not be fresh coffee beans.

Second, appearance: This is only applicable to the darker roast (aroma roast degree deep roast ~ deep roast) coffee beans. Before grinding, look at the coffee beans table. The oily feeling on the foggy surface means that it is not fresh coffee beans. To learn to judge this point is very simple, it is easy to see the market "only marked expiration date" coffee beans, buy back to observe to know. Light roast (equivalent to aroma roast light ~ medium +) coffee beans are difficult to judge from the appearance of fresh beans.

Third, grinding: fresh coffee beans after grinding, regardless of hand or siphon, brewing is easy to see expansion or thicker powder layer.

Second move: flavor

Complex Flavor

Coffee is the most complex natural drink in the human world. Through our simplification, we can tell you what you have learned directly; let you not waste money and pick the coffee beans that suit you.

The Specialty Coffee Association of America (SCAA) has always been committed to defining the coffee language so that coffee lovers can communicate with each other. Good intentions and hard work are also commendable. Unfortunately, the contents are too complicated and unsuitable for circulation by the general public.

For now, academic scholarship aside, start from practical experience. Here are a few quick steps to pick your favorite flavor.

First understand how raw beans are processed

"Wash beans" the best way to remove the impurities and ensure the consistent quality of coffee beans. Water-washed green beans have a bright, clean acidity and are less offensive.

Sun-dried beans: The ripe coffee fruits are picked, sun-dried and then processed. This method can completely retain the fruit content; bring low fruit acidity, thick aroma, sweetness, taste and other high-quality flavor.

"Honey treatment" 100% pectin is reserved and dried on a shelf off the ground. The honey-treated coffee beans retain the sweetness and aroma of the coffee pulp, and have a heavier taste than the washing method.

"Wet Peas" Remove seed husks in advance and proceed with drying procedure. This helps to shorten drying time quickly and reduce the sourness produced by fermentation of green coffee beans. Also created a mellow, woody, fruity, fairy grass flavor.

Wind Stain Bean has been exposed to humid monsoon environment for a long time. The color of coffee beans changed from dark green to brown rice, and the fruit acid flavor of coffee was almost gone. Fengzidou has a strong nutty and shell flavor, drinking tea feeling full, very similar to black rice tea flavor.

Correlation between processing methods and flavor of green beans

Compare this to the "same coffee".

Flower fragrance washed beans> honey treatment> sun beans> wet planed beans> wind stained beans

Sun dried beans> Honey treatment> Wet planed beans> Washed beans> Wind-soaked beans

Acidity washed beans> honey treatment> sun beans> wet planed beans> air-soaked beans

Sweetness Solarized beans> Honey treatment> Wet planed beans> Washed beans> Wind-soaked beans

Third move: baking degree

Baking degree vs. Flavor

Light ~ medium roast + coffee beans

Shallow baking: full of aroma and strong acidity. Suitable for you with "special needs"

Medium roasting: retains most aroma and bright fruit acid; it is recommended for coffee "the shallowest roasting degree" for beginners.

Medium baking +: soft and sweet with sour fruit

Because there is little damage to the cell wall, and most of the oil is still preserved in the cell wall of the bean body. The degree of carbonation is not deep, retaining the flavor and sour taste of the beans themselves (the special local / regional flavor of the producing area). After high-quality roasting, boutique coffee beans can drink fruity / sour aromas such as apples, lemons and oranges.

Medium and deep roasted coffee beans

Medium and deep baking: at the expense of most of the acid and fragrance, the aromas of → caramel, nuts, malt and chocolate brought by the caramel reaction begin to highlight.

Deep baking: the taste is mellow and caramelized so that the flavor begins to be bitter. Because of the large firepower baking, there is an obvious smell of wood and smoke.

The cell wall is carbonized and coffee oil is added to add a mellow taste. Medium and deep roasting will have obvious flavors of nuts, caramel and chocolate, while deep-roasted coffee beans are easy to drink wood, spices, tobacco and other flavors.

Fresh coffee beans should be ground to use hot water to extract the flavor, of course, with utensils, techniques, etc., it is recommended to use segmented extraction.

Knowledge expansion: "fresh definition" coffee beans are stored in an one-way breathable bag and stored at room temperature. "within two weeks after baking" are considered fresh coffee beans.
