When you choose hot coffee or iced coffee, your judgment may be based on the mood or the weather outside. The difference in temperature is not the only reason, but there are also amazing differences in the health benefits of drinking hot coffee and iced coffee. No matter what the temperature is, drinking coffee has many benefits. Drinking coffee in moderation can help reduce depression, reduce the risk of diabetes, improve exercise and promote brain function.

1: hot coffee contains more antioxidants. There is a "chemical difference" between hot extraction coffee and cold extraction coffee. Hot coffee contains higher levels of antioxidants than cold coffee, which makes hot coffee slightly healthier. This is important because antioxidants have an important effect on your health benefits from coffee.

2: cold extraction usually contains less caffeine. The amount of caffeine in coffee varies depending on how it is ingested. The benefits of less caffeine include better sleep, hormonal balance in women, and lower blood pressure.

3: iced coffee can help prevent heart attacks. Coffee is very good for human health because it is rich in antioxidants and can help people stay away from many diseases, and iced coffee is especially helpful in preventing heart attacks. Iced coffee has a wide range of benefits because it contains caffeine, magnesium, trigonelline and phenols, which can stabilize blood pressure, increase insulin sensitivity and lower blood pressure. "drinking coffee every week-hot or cold-can help reduce the risk of a heart attack by 7%.

4: a wisp of hot coffee aroma is enough to reduce sleep deprivation caused by stress and fatigue.

1. Hot coffee is made with hot water above 80 degrees Celsius or above 85 degrees Celsius. Second, it must be extracted quickly, because too slow will cause excessive coffee extraction to cause miscellaneous smell, and the main substance causing miscellaneous smell is tannin, which will be decomposed into pyrouric acid after boiling, and tannic acid can be easily dissolved and decomposed in hot water. It is the main culprit that causes our coffee to be too bitter, and we generally have to be careful not to extract too much tannin and caffeine. This is the basic common sense that our coffee lovers know for a long time.

2. Ice drop coffee is extracted with a temperature that must be lower than 5 degrees or even close to the freezing point, so the various ingredients contained in the coffee are not easy to extract in ice water, so it is necessary to take the way of fine grinding and slow extraction. the specific method is to soak the coffee powder in ice water for a long time and extract it at a very slow drip rate. The general standard speed is 1 drop per second, 45-50 drops per minute. It usually takes about 8-12 hours. Although it takes a long time to wait, its biggest advantage is that the tannic acid we hate most does not decompose at all in cold ice water, and caffeine decomposes a little in ice water, but it is about 90% less than hot water extraction. there are also many other major ingredients in coffee. It is precisely because the ice drop coffee has no astringency at all, and the bitter taste is very little, so the ice brewed coffee is very pure in taste.
