The question of how soon the aftertaste kicks in varies from person to person, some people may feel drunk as soon as 2 hours after drinking and some may not feel well until the next day. Rum is a spirit with an alcohol content of between 38% and 50%. The high alcohol content of rum makes it easy to get drunk and still have a strong aftertaste. The average rum is 35 to 65 proof. Rum alcohol span is still relatively large, although there are many varieties around the world, but the domestic is not particularly common, more than 65 degrees is rare, and may not be suitable for Chinese people's tastes. If you distinguish by flavor, can be divided into strong flavor, medium flavor, light flavor 3 kinds, a little like our white wine soy sauce type, clear flavor type, strong flavor type. Therefore, the usual alcohol concentration is also gradually increased from light to strong. Light rum, which is lighter, is a cocktail base and an ingredient for mixing and other beverages. The high content of "impurities" such as methanol, acetaldehyde and "mixed alcohol oils" has a great deal to do with the fact that these "impurities" are abnormal metabolic products of microorganisms, and the body's osmotic function rejects the passage of these substances. The body's osmotic function rejects these substances through, these substances from the original way back to the digestive organs, and then rushed to the head, which is the cause of the latter.
