What are the differences between wooden wine bottles and stainless steel barrels used for wine brewing? In addition, what role does it play in the process of wine brewing?

1、分别利用各自特性

1. Use their own characteristics

用于葡萄酒酿造的木质酒樽和不锈钢酒桶存在哪些差异呢？

What are the differences between wooden wine bottles and stainless steel barrels used for wine brewing?

二者在气密性和温度控制上存在较大的差异。仅使用果汁酿造而成的白葡萄酒，为了保留其香味特征，通常在不锈钢酒桶中进行酿制。由于不锈钢酒桶易于温度控制，红葡萄酒也多使用不锈钢酒桶而倘若想要赋予葡萄酒特有的木质香味时，则使用木质酒樽。

There are great differences between them in air tightness and temperature control. White wine brewed only with fruit juice is usually brewed in stainless steel barrels in order to retain its aroma characteristics. Because the stainless steel barrel is easy to control the temperature, the stainless steel barrel is often used for red wine. If you want to give the unique wooden flavor to the wine, use the wooden bottle.

无论哪一种方式，为了让发酵后的酒更加圆润的熟成，木质酒樽和不锈钢酒桶皆是葡萄酒悠闲歇息的场所。

Either way, in order to make the fermented wine more mellow and mature, wooden wine bottles and stainless steel wine barrels are places for wine to relax.

2新樽和旧樽

2 new bottles and old bottles

被使用一次以上的酒樽称为旧樽。由于酒樽香味成分的提取情况要比新樽少，所以在不需要赋予葡萄酒酒樽香气，或者需要赋予其沉稳的酒樽香气时，多使用旧樽。新樽的香气易于浸透，在葡萄酒本身质量不佳的情况下，只能形成具有木樽味道的葡萄酒。根据葡萄品种和意向香味特性，可以调整比例和酒樽熟成时间。

A wine bottle that is used more than once is called an old bottle. Because the extraction of aroma components in wine bottles is less than that in new bottles, when it is not necessary to give wine bottle aroma or give it steady bottle aroma, use old bottles more. The aroma of the new bottle is easy to soak. When the quality of the wine itself is poor, it can only form a wine with the taste of wooden bottle. According to grape varieties and intended aroma characteristics, the proportion and bottle ripening time can be adjusted.

3、法国橡木酒樽和美国橡木酒樽

3. French oak bottle and American oak bottle

酒樽的原料是橡木，法国出产的橡木木纹细腻，能赋予葡萄酒优良的香草气息，同时增加其复杂性。

The raw material of the wine bottle is oak. The oak produced in France has fine wood grain, which can give the wine excellent vanilla flavor and increase its complexity.

而另一方面，美国橡木赋予了葡萄酒椰子和牛奶糖果般甘甜香气，同时香草的香气也强烈浓厚。

On the other hand, American oak gives wine a sweet aroma like coconut and milk candy, and the aroma of vanilla is also strong.

4、烤制的香味特性

4. Aroma characteristics of roasted

在酿造酒樽之时会用火对酒樽内侧进行烤制。根据烤制程度，葡萄酒的香味特性便会发生变化。烤制程度分为请、中、重三个阶段。一旦烤制程度重，那么葡萄酒便会出现咖啡或熏制般的香气。

When brewing wine bottles, the inside of the wine bottles will be baked with fire. According to the degree of baking, the aroma characteristics of wine will change. The baking degree is divided into three stages: please, medium and heavy. Once roasted, the wine will have a coffee or smoked aroma.
