1, healthy
According to the regulations of organic wine, the content of sulfurous acid should not exceed 100mg/L per liter, because sulfurous acid is the main cause of headache caused by excessive drinking, and the content of polyphenols, resveratrol and anthocyanins in organic wine is 50% higher than that in ordinary wine.
It is required that the sulfurous acid content of common wine should not exceed 150mg/L per liter, and the prescribed boundary is vague. Some producing areas do not have strict standards, and even the nitrite content will be higher. Moreover, there are too many chemicals in the wine, which has a bad influence on people who are allergic or have asthma.
2. Environmental protection
Organic grapes grow naturally, there is no artificial intervention in the grape production process, and substances that are not conducive to environmental sustainable development such as fertilizers and pesticides are not used. For example, Ma Fei of France, the largest organic wine producer in Bordeaux, has been fallow for three years and started production in the fourth year. Only natural fertilizers are used instead of artificial irrigation. Every bottle of wine has not been exposed to chemical fertilizers and pesticides. Secondly, organic wine is naturally fermented, using the interaction between the sugar in the grape itself and the yeast on the grape skin without using any additives.
In the future, ordinary wine will make grapes more productive in the process of grape growth, and will supplement nutrition through artificial fertilization, using herbicides, pesticides and other chemicals that are easy to destroy the natural ecological balance. To some extent, these chemicals will change the soil, which is not conducive to environmental protection (25% of pesticides in France are used in agriculture).
Step 3 taste
Organic wine has a natural and mellow taste, which can well retain the original local characteristics. Grapes without artificial intervention will absorb more minerals in the local soil and be more representative of the local area. The taste of wine is a mixture of various grape juices, which is completely pure without manual triggering.
Ordinary wine, on the other hand, has a higher alcohol concentration because of human intervention: chemical substances such as fertilization, herbicides and pesticides will affect the characteristics of grapes themselves, plus artificial fermentation and sugar addition during brewing; Adding yeast has better stability. The addition of these raw materials changed the original characteristics of wine, weakened the differentiation of taste and lacked local characteristics.
4. price.
Organic wine is about 25% more expensive than ordinary wine of the same grade. Although the price of organic wine is high, it is still highly accepted by the public.
