Question:
what are the raw material distilled brandy made of?

Answer:
brandy (Brandy) is a distilled liquor, is a fruit as raw materials, through fermentation, distillation, storage and spawned. Brandy can be divided into fruit brandy (such as apple brandy) and grape brandy two categories, while the largest number of the latter, often directly referred to as brandy. In the brandy, the main Cognac (with wine, distilled) and the bran brandy two broad categories.  The grape varieties used to produce cognac is mainly neutral (almost no fragrance) variety, the best white wine grape of the original, relatively low alcohol content, higher acidity, there is no deal by sulfur dioxide. For the production of bran brandy grape varieties are mainly aromatic varieties.  brandy distillation methods are mainly of non-continuity and continuity of pot distillation tower distillation. However, no matter in what way, the distillation of wine alcohol content should be less than 86% (V / V), the total volatiles should be more than 1.2g / L (pure alcohol), methanol concentration should be less than 2.00g / L (pure alcohol). But now most of the brandy distillation tower of continuity is applied.  bran brandy distilled mainly uses steam distillation, of course, other distillation methods can be used, but in different ways by steam distillation residue obtained brandy leather chemical and sensory analysis is not much difference. The new steam out of brandy should be at least more than a year aging in oak barrels. In the aging process, regardless of the material originated from oak or distillate own physical changes are caused by oxidation.  finished brandy alcohol content is usually 40-43% (V / V), therefore, in most cases, the former bottling brandy should be deployed to reduce the alcohol content, and adjust the other ingredients. Should be accompanied by low-temperature processing and filtration, in order to prevent the precipitation of some elements in the bottle.

问题:
白兰地是有什么原料蒸馏而成的？

回答:
白兰地（Brandy）是一种蒸馏酒，是以水果为原料，经过发酵、蒸馏、贮藏而酿成的。白兰地可分为水果白兰地（如苹果白兰地）和葡萄白兰地两大类，而以后者数量{zd0}，往往直接称为白兰地。在白兰地中，主要有白兰地（用葡萄酒蒸馏）和皮渣白兰地两大类。用于生产白兰地的葡萄品种主要是中性（几乎没有香气）的品种，其葡萄原酒{zh0}是白色、酒度较低、酸度较高，没有经二氧化硫处理。用于生产皮渣白兰地的葡萄品种则主要为芳香型品种。白兰地的蒸馏方式主要有非连续性的壶式蒸馏和连续性的塔式蒸馏。但无论采用何种方式，其馏出酒的酒度应低于86％（V/V），挥发物总量应大于1.2g/L（纯酒精），甲醇含量应低于2.00g/L（纯酒精）。但是，现在大多数白兰地则采用连续性塔式蒸馏。皮渣白兰地的蒸馏主要采用蒸气蒸馏，当然，也可采用其它蒸馏方式，而且用不同蒸馏方法所蒸得的皮渣白兰地的化学和感官分析结果没有多大差异。新蒸出的白兰地至少应在橡木桶中陈酿一年以上。在陈酿过程中，无论是源于橡木的物质还是馏出液本身的物质的变化，都是氧化现象所引起的。成品白兰地的酒度一般为40-43%（V/V），因此，在多数情况下，装瓶前应对白兰地进行调配，以降低酒度，并调整其它的成分。同时还应进行低温处理并过滤，以防止一些成分在瓶内沉淀。
