在收藏天下app下载中，你知道吗？为什么葡萄酒会有那种小玻璃碎片一样的东西旋转或粘在软木塞底部？这些其实是无害的酒石酸晶体。欢迎来到葡萄酒酸度的奇异世界。这些酸性成分可能很复杂，但它们是决定葡萄酒外观、味道和制作方式的基础。

据宾夕法尼亚州的酿酒顾问丹尼斯·加德纳 (Denise M. Gardner) 说，我们的嘴会本能地对酸度做出反应。想知道葡萄酒的酸度如何?喝完后嘴巴要张开。如果你开始流口水，你的嘴就会对酸起反应。唾液越多，酸性越强。

pH 值 葡萄酒含有许多酸，但葡萄中天然存在的两种主要acid是wine stone acid and apple acid. 我们通常所说的 acidity in wine is actually called total acidity or titratable acidity. “Titratable acidity works with our mouth’s response to liquids,” says Denise M. Gardner, a winemaking consultant from Pennsylvania. “The more saliva needed to interact with the liquid, the more acidic it tastes,” she explains.

Titratable acidity is related to pH value but measures different things. Titratable acidity measures the amount of acid while pH measures its strength on a scale of 0-14, where 7 is neutral.

Typically, if a wine has higher levels of acidity, its pH value will be lower as well. High-acidity/low-pH wines are stable because their environment hinders bacterial and other microbial growth.

Another important thing to remember is that the numbers on the scale are logarithmic; not linear so pH 5 isn't twice as acidic as pH 6 - it's actually ten times more acidic!

“I think pH values have more chemical aspects [to them],” says Alison Thomson, owner/vintner at LA Lepiane Wines in Santa Barbara County California. “Acidity has more to do with these acids' flavor characteristics.” Acidity makes white wines taste like lemonade - they make you pucker up and want to drink more! Then I think the pH value reflects how stable your wine will be.”

How does this affect your wine?

Acidity affects both appearance and taste in glass cups: The lower the PH level means higher levels of tartness for red wines; resulting in brighter red hues since they turn redder due to low PH levels whereas high-pH reds appear blue or purple due mainly for oxidation reasons which might cause unpleasant colors especially when young white wines come into play.

For whites however such changes aren't quite so noticeable except perhaps upon aging where some people find them rather off putting yet there's no denying one could love an elegant richly flavored experience when done right though getting too little then combining that w
