2015-12-16 Coffee roasting techniques key points process medium hair raw basic chemical reactionThe taste and extraction methods of coffee are very diverse. The European Fine Coffee Association once put forward the concept of Gold cup, that is, the golden cup criterion. A certain extraction rate and coffee concentration determine the taste of coffee. But what is the extraction rate, and what is its effect on the taste of coffee?. Let's do some knowledge sharing what is the Golden Cup Criterion (Gold Cup Standard) SCAA Golden Cup
2016-05-10 Coffee extraction theory gold cup criterion specialty knowledge coffee tasteThe proportion of SCAA fine cup coffee defined by the Gold Cup Fine Coffee Association of the United States and the scae European Fine Coffee Association must be about 20% of the coffee extraction rate, while the TDS is about 1.1% to 1.3%. For Drip Filter dripping and brewing, how to extract the best coffee flavor is controlled by two variables: the extract of coffee powder and the concentration in a cup of coffee.

2016-01-23 Coffee roasting process medium hair raw basic chemical reaction degree produced madeAccording to the research of Dr. Lockhart and Ringo, a senior consultant of SCAA (American Fine Coffee Association), as far as coffee extraction is concerned, the dissolution rates of flavor molecules and hot water often vary according to molecular weight and polarity. Coincidentally, the low molecular weight sour aroma of flowers and fruits, as well as the taste of nuts and toast, as well as the cereal and rice and wheat flavors produced in the early stage of the Mena reaction will be excellent.

According to the idea of coffee flavor wheel to make, starting from the central point to explain in detail the impact of each point on flower drawing and different, no more gossip, let's go straight to the topic. We can see from the picture that I have divided the factors affecting flower drawing into four categories: coffee, milk, mugs and patterns.

The maximum extraction rate of roasted coffee beans is 30% (substances that can be dissolved in water divided by the total weight of coffee). This seems to be nonsense: 1. Whether it's French pressure, Philharmonic pressure, all kinds of pressure, or espresso. The range of the best extraction rate is 18% Mui 21%. Insufficient extraction (less than 18%) indicates that the flavor of coffee is not fully soluble.

Let's talk about extraction first.

At this point, you need to increase the amount of powder (to get more concentrated dose) to enhance the concentrated flavor of the milk coffee. On the contrary, pure black coffee or small-dose milk coffee need to reduce the amount of powder. Milk coffee in many boutique cafes, strong

The main thermally reactive components are monosaccharides and sucrose, chlorogenic acid, displaced amino acids, and trigonelline amide. Both aravinone and calactose in polysaccharides are transferred, and basic sulfurization contains hydroxyamino acids.

According to SCAA theory, up to 30% of the material will be dissolved in water. In general, if the substance dissolved in water occupies the coffee
