问题 问答题 简答题

如何对白酒的品质进行感官评价?

答案

参考答案:

从色、香、味、格四个方面来进行鉴别的。

(1)色泽透明度鉴别

白酒的正常色泽应是无色透明(酱香有淡黄色),无悬浮物和沉淀物的液体。将白酒注入杯中,杯壁上不得出现环状不溶物。将酒瓶倒置,在光线中观察酒体,不得有悬浮物、浑浊和沉淀。

(2)香气鉴别

在对白酒的香气进行感官鉴别时,最好使用大肚小口的玻璃杯,将白酒注入杯中稍加摇晃,即刻用鼻子在杯口附近仔细嗅闻其香气。或倒几滴酒在手掌上,稍搓几下,再嗅手掌,即可鉴别香气的浓淡程度与香型是否正常。

(3)滋味鉴别

白酒的滋味应有浓厚、淡薄、绵软、辛辣、纯净和邪味之别,酒咽下后,又有回甜、苦辣之分。白酒的滋味评价以醇厚无异味,无强烈刺激性为上品。感官鉴别白酒的滋味时,饮入口中的白酒,应于舌头及喉部细细品尝,以识别酒味的醇厚程度和滋味的优劣。

(4)风格鉴别

也就是辨别香型是否典型,需要对我国白酒的香型特点有一定了解,在品尝中通过香气和滋味的综合评价,确定是什么香型,是否典型,有什么特点。

白酒总的特点是酒液清澈透明,质地纯净,芳香浓郁,回味悠长,余香不尽。

     Everyone's at it, even my neighbors. I thought I might be the only person left in the world who

hadn't done an eBay deal. So, I decided to try my hand at online auction (网上拍卖).

      Buying for Beginners

      Sign up on www. eBay. co. uk. Most items (e.g. tables, computers and books) ready for auction will

come with a picture and a short description; others may be marked with"Buy It Now" and have a fixed price.

You can buy these right away.

      If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids (出价)

for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and

asked if you would like to bid again. Auctions last up to 10 days and when they finish, you get an email telling

you whether you have won the item.

       How to Pay

       Sellers decide how they would like to be paid and you need to check this before placing a bid as you

might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system

that takes the money away from your credit card.

      Selling Made Simple

      If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends' advice and put

up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends

to bid.

      The big Things in Life 

      It's easy to post a small item, but furniture is a big part of eBay and this has to be collectively sent by

deliverymen. Check the ways of delivery before you bid.
