The main choice of sugar in coffee is yellow sugar, white sugar and cube sugar.

Sugar can be divided into white sugar, brown sugar and yellow sugar according to color. The difference in color is due to the different degree of removal of impurities in the sugar-making process. White sugar is refined sugar, the purity is generally more than 99%; yellow sugar contains a small amount of minerals and organic matter, so it has color; brown sugar is unrefined crude sugar, the color is very dark.

Generally speaking, white sugar and yellow sugar are suitable for seasoning in coffee or black tea, and yellow sugar is often used in cooking dishes. Yellow sugar contains more nutrients, which has the effect of tonifying blood and warming the stomach; white sugar has a clearer taste, cooler and better color.

There are mainly three kinds of sugars for coffee: yellow sugar (sucrose), white sugar (refined sugar) and cube sugar (crystal refined sugar compression drying).

Most people have a consensus on the answer of drinking milk tea with white sugar, but there is more debate about whether to drink coffee with white sugar or brown sugar. Espresso from Europe traditionally contains granulated sugar, or even powdered sugar finer than granulated sugar. However, coffee culture has spread to Asia, first to Japan and Taiwan, and then to Hong Kong and even mainland China. The concept of coffee and sugar and milk has become very common, and it has not been said that white sugar or brown sugar is traditional and authentic, and the choice of sugar can be determined by individual taste.

As for whether putting white sugar and yellow sugar has any effect on the taste of coffee, the answer is yes, the principle is the same as putting seasoning in the kitchen. If brown sugar refers to Raw Sugar rather than dyed so-called "yellow sugar", the sugar itself has the sweetness of sugar cane, and the addition of coffee will give the coffee a slight taste of sugar cane and caramel, while refined granulated sugar will only add pure sweetness to the coffee.

Yellow sugar is generally thicker than white granulated sugar. Will slow dissolution affect the taste of coffee? The roughness of brown sugar commonly used in the market has little effect on the taste of coffee. In fact, in addition to granulated sugar and brown sugar, you can also try to find out the difference in the taste of coffee with honey, maple sugar and black sugar. Even supermarkets sell all kinds of blended coffee sugar. Generally speaking, coffee lovers prefer sugar because the ingredients are more natural and contain fewer additives, and most people think that they are healthier. In terms of sweetness, the sweetness of white granulated sugar comes directly, but modern people pay attention to health, and sucrose, which has a low refined system, has become the choice of many people.

Cube sugar, also known as semi-cube sugar, generally refers to white sugar, which is processed by refined sugar. it is characterized by pure quality, white and glossy, complete edges and corners, proper firmness, not easy to break, but dissolves quickly in water, and the solution is clear and transparent.

Some people say that "there is no sugar in good coffee" or "people who can drink coffee don't put sugar in it". In fact, tasting coffee without sugar or milk is one of the ways to know the taste of coffee, but it cannot be judged by this method alone that people who put sugar and milk will not drink coffee. The purpose of putting sugar in coffee is to subtract bitterness, whether to put sugar or not, or which kind of sugar can be put according to mood. Coffee tasting this kind of leisurely activity is the most comfortable.
