第一次 阅读，希望能有个好的开头，请大牛评价~
说实话有许多看不懂的地方，但是我就捡看得懂的地方缕清思路。
Time 2: Use 3:33
The alcohol concentration of the wine becomes higher and higher because of the popularity of the fruit flavor.
But the high alcohol concentration of wine is bad for health.

Time 3: Use 2:59
Some people think high-alcohol wine taste better. However, others find the problem brought by the high-alcohol wine that is

drinking too much alcohol may bad for health and well-being. And some see other problem that moderate wine may better suit for

food.
At the end, it says that technology may find way that drunk people can drive home.

Time 4: Use 2:22
The ways to produce good flavor wine with low alcohol meet challenges. Some people try things to do that.
At the end, it says that there is a motivation that find a simple thing that the winemaker can easily use.

Time 5: Use 3:40
A group of people did a research and found few wild yeast could make wine with low alcohol and good flavor.
Someone contacted some winemakers who are interested in the wild yeast, and different wild yeast could result in complexity of

flavor of the wine with low-alcohol. That's a win-win situation.

Time 6: Use 2：38
The discovery of new wild yeast is not finished. And the winemakers may not doubt the flavor the wild yeast may produce because

of the advices of the scientists. But a research showed a little different.
At the end, it says that there may be a new yeast that could make the wine low alcohol without hurting its quality.

Obstacle: Use 9:22
This article is talking about hangover and its cure.
Firstly, it introduces that the cost of hangover in USA is huge, so hangover draw people's attention.
Secondly, it introduces the cause of hangover and how human body act to reduce alcohol.
Thirdly, it introduces some cures that may help reduce the alcohol and heal hangover and some researches to develop the cures.
At the end, it shows some people don't agree with the attitude of those researches. They think people want to drink and hangover.

that flavors added in the wine will produce yeast make it boozy.
time3 155
high-alcohol wines receive more praise, while it also will influence the odor and match with food.
time4 142
preserving flavors while reducing alcohol is challenging, many people failed, there is a promising approch to achieve it, namely find a simple something with desired traits.
time5 150
this method makes sort of progress; a wild yeast produces complex odors but high alcohols
time6 148
despite many problems,informal taste tend to be liked by many people, and it's also possible to find something which makes the best of both worlds.

Thanks for sharing! It's quite interesting!
02:47-> The high concentration of alcohol can benefit or harm the wine taste;
            The wine with high alcohol may not suit for table.
01:45-> Scientists try to produce the weaker dry wine.
02:47-> the new method found by scientists
            this method add new taste to the wine.
01:11-> By understanding the process how yeasts  make wine, wine of better quality can be made.

Hangover is a bothering pb for longtime and scientists try to figure it out.
Different experiments about exploring the cause of hangover: Ast1, Ast2, Cong
Different experiments about exploring the cure of hangover: 4 beverage

Time 1
From a recent examination, scientists found that alcohols only benefit minority of people who have certain genes.
Time 2
How to produce flavors associated with high alcohol wine without the accompany effects on blood-alcohol content.
Time 3
More alcohol can counterproductively dampen the characteristic bouquet of the wine.
Time 4
It is hard to keep the flavor of the wine while reduce alcohol. One possible approach is to find wild yeast that already has desired traits.
Time 5
Producers use a panel of yeast strains to lower alcohol contents in finished wine. At the same time, this method adds interesting flavor complexity to wine.
Time 6
Scientists should continue to find where all the sugar not being converted into ethanol is going.
It is found that only one strain variability works for two kind wines avoid harming quality and more need to be tested in coming future.

timer 2:  2:18'91
recently the alcohol content of vine are increasing, a side effect of richer flavors.  because wild yeast will turn sugar into alcohol during fermentation.

timer 3:  2:44'86
higher-alcohol wines have some negative impact.

timer 4:  2:26'41
it's difficult to produce weaker dry wine. AB offers a solution, and they do so.

timer 5:   4:04'06

Drinking alcohol is only availuable to certian people, who happen to have right genes.
To test whether alcohol is benefit for people's heart, scientists compare some men and women, who have heart disease, with other healthy volunteers. In the end, the research reveals that only the people who get the gene, which can work only with booze, lower their probability to get heart disease risk.
However, only 15% of us have this genes. Moderate drinking is good for only this small lucky gene group, and most of us do not get any benefit at all.
Futher experiments and studys are needed to do to test whether the conclusion is right, but we still keep in mind that maybe drinking alcohol is not good for our health.

To reduce intoxication, scientists have begun to study a new yeast, which can turn small sugar of grape juice into alcohol,to replace the traditional one. However, such a study does not care the side effect that the new kind of wind will bring, and just concern the quality of wines, leaving many healthy problems.
Such a kind of wine demands grapes to hang on the vine longer to contain bigger sugar. The more suger the yeast has to work with, the more alcohol it will make.
Time3 2'23

In the market, we can find that wines with high alcohol has better comments than normal one. What is more, having more alocohol makes the violate components in the wines reluctant to diffuse. Stiffer wines may have higher taxes.
However, customers should concern whether drinking such high alocohol wines will result in healthy problems, because such kind is not the so-called wines, literally. Consumers may should consider choosing wines with moderate alcohol.
Time4 1'44
Scientists have tried lots of methods to improve the quality of wines and preserve the ripe flavours, while reduing the alcohol, but they get limitions at the end.
Alan has studied wine yeast for a long time, and he said that the certain method is using modified grape, which customers may not like. So, probably the best way is to find wild yeast, making the winemakers use it easily.

ethyl acetate 乙酸乙酯

No one had found such a wild yeast that could lower alcohol and not hurt the quality of wines. Scientists made an experiment to find which yeast could produce lower alcohol, and they just found 4 kinds of them produced lower than S.cerebosiae did.
To winemakers, they tend to make their productions complex. Using dual yeasts may causes higher alcohol, but they can make fewer voliate acids and enhance the complexity of the wine, meaning that winemakers could use different yeasts to creat different alcohols and to lower the alcohol in the same time.
Time6 1'26
Informal taste tests are promising, and there still another strain of yeast of some species is still awaiting people to discovery.

main idea: The main reasons that cause hangover and how to cure it.

Scientists found that human body cannot metabolize alcohol fully, so that people always feel nausea and other bad side effects at the next day after drinking alcohol at night.
It seems that acetaldehyde is the main factor that causes hangover.
How to cure hangover? Chinese scientists found that imbibe little softer beverage, such as Sprite and 7-UP, can help. Meanwhile, drinking some coffee an an aspirin can also cure your hangover.

P7: Curing aftermath from hangover is always a task. Give Greeks, Roman, and Sicilians examples
Huge cost in US from hangover. Scientist can study body. E.g. cause of headache
Explain hangover cause. Key word: ADH, ALDH.
Symptoms of hangover
2000 study: role of acetaldehyde. Japanese researcher more research: complications of patients with mutant enzyme.
More researches on acetaldehyde. Acetate may be good and bad (hangover headache)
Congeners results from process and links to intoxicating effects.
Chinese researchers find chemicals that breakdown acetaldehyde and acetate, and green tea prevent metabolism of alcohol. Soft drinks can help metabolize toxin.
Caffeine and aspirin can help to ease headache. Also nano technology makes enzyme helps to break down alcohol.
Concerns: The hangover research only study not so bad hangovers.

The author explains the reason why wine has gotten boozier.

【Time 3】
Actually, more alcohol wine has, more bouquet it losses. And the author also explains the reason detailedly to us. Moreover, the author introduces the disadvantage of stiff wines.

【Time 4】
However, the author claims that it is hard to produce weak wines from ripe grapes. Then, the author tells about several approaches to make it happen, but all of them are limited.

【Time 5】
Here is a simple but good approach: finding a wild yeast that already has the desired traits. By trying this approach, the author claiming, a wild yeast not only lowers alcohol without hurting quality but also adds interesting flavor complexity to wine.

【Time 6】
But the work to develop the new yeast is continuing.
