Drawing Challenge #7 Two Wineglasses X Science Pic / 繪圖挑戰 #7 两只酒杯 X Science Pic

上次因為要鉛筆素描所以不得不放棄一次參加 @helene 的 #drawingchallenge 帖, 今次可以再次回來混一下, 混一下科學, 再度和 #sciencepic 一起來。

Last time due to its requirement to be pencil sketches so I have to give up last competition, this time is free for all, so I can come back with more science, another cross over with #sciencepic~

這句每次也要講明一下
再一次説明我不擅長畫畫, 請見諒XD
Once again I must state, I am not good at drawing XD

完成品：
Final product

我用ipad mini，與 bamboo手寫筆，和應用程序 sketches
I am using my ipad mini, Bamboo stylus fineline, and the application Sketches

葡萄酒怎能沒葡萄
how can wine goes without grapes?

又來點科學
Here comes the science bits

根據定義，葡萄酒是由葡萄發酵製成的酒精飲料，最早的葡萄酒來自中國〜紅酒是最常見的葡萄酒，因為它直接由葡萄釀造而成。 葡萄酒的紅色來自葡萄皮, 葡萄皮含有豐富的植物色素花青素, 我在變色秋天中提到過的。它們是植物最常用的色素之一。

By definition, wine are alcoholic drinks made from grape fermentations, and the earliest trace of wine comes from China~ Red wines are the most common form of wine, as it is made directly from mashing up of the grapes. The redness of the wine comes from the grape skin which is rich in the plant pigment anthocyanin which I mentioned before in my color changing autumn, they are one of plant's most common pigments.

許多人會知道，酒和許多其他酒精飲料是通過發酵製成的。發酵將葡萄中的糖變成酒精和二氧化碳，這個過程通常是由酵母菌進行的。 酵母菌實際上是一種的真菌，在發酵過程中，酵母菌也會代謝其他生物分子，這些有機生物分子依次決定了葡萄酒的味道。 不同的葡萄（不同的生物分子原料），不同的酵母菌（不同的發酵生物），不同的發酵過程，例如， 溫度，時間（生物分子不同的發酵條件），所有這些都會導致葡萄酒的味道和氣味不同。 這就是為什麼某些葡萄酒年份可能比其他葡萄酒品嚐更好，葡萄種植的一切都決定了葡萄酒的質量〜甚至釀酒行業的科學家也不能保證葡萄酒的質量一致〜

As many of you will know, wine and many other alcoholic drinks are made by fermentation. Fermentation turns the sugar in the grapes to alcohol and carbon dioxide, this process is usually carried out by yeast. The yeast are actually a type of fungi, during the fermentation process, the yeast will also metabolize other biomolecules, those organic biomolecules in turns determine the flavor of the wine. With different grapes (different starting biomolecules), different yeast (different fermentation organism), different fermentation processes eg. temperature, time (different conditions for biomolecules modification), all those will lead to different taste and smell of the wine. This is why certain vintage may taste better than others, everything from the growing of grapes determines the vintage quality~ Even scientists in the wine making industry cannot guarantee a consistent outcome of the wine~

所以如果你在家裡有一些好年份的紅酒,乾杯〜
So if you got some good vintage at home, cheers to that~
