評價啤酒質量的指標，你知道幾個？

隨著精釀啤酒行業的興起，越來越多的啤酒愛好者對啤酒文化的了解日益深入，啤酒消費者的專業程度越來越高。這也意味著只有釀造出真正高質量的啤酒，你才能在精釀行業擁有一席之地。有人说啤酒質量好不好，尝一下就知道了。那么究竟是哪些指标决定了它的口感与风味，能让人尝起来觉得好呢？今天我们就来探讨一下这个问题。

一、原麥汁濃度
      国际上一般以麦汁浓度标注啤酒的度数，单位为“°P”。它表示的是啤酒发酵前单位原麦汁中所含浸出物的含量，由于麦汁浸出物中的主要物质就是糖类，所以我们又习惯于把原麦汁浓度称为“糖度”。
      不同风味的精酿啤酒原麦汁浓度会根据工艺的不同有所区别。当麦芽汁浓度为7°～9°时，我们称之为低浓度啤酒。麦芽汁浓度在18°～20°的一般是黑啤酒。原麦汁浓度越高，营养价值越好，同时泡沫细腻持久，酒味醇厚柔和，保质期也较长。
二、酒精度
      通常会有人把原麦汁浓度与酒精度搞混淆，实际上这是两个概念。酒精度是指单位啤酒中酒精的含量，用“%vol”表示。不过它与原麦汁浓度呈正相关关系，麦汁浓度越高，酒精度数越高。
      麦汁浓度在6°～8°范围内，酒精浓度大约为2%vol，這種啤酒稱爲低度啤酒，和一般飲料差不多，口感清涼，不過穩定性比較差，不適合長時間保存。而中度啤酒麦汁浓度在10°～12°范围内，酒精浓度则在3.5%-4%之内，我国的中高端啤酒主要在10°左右。麦汁浓度在12°- 20°范围内，酒精浓度在5%-10%之内，称为高度啤酒。12°是國際上公認的高品質啤酒。
三、色度
      色度是指啤酒中色素物质的总和，可用纳氏比色管肉眼比色，或用EBC比色计测定。通常我们在精酿啤酒馆能看到一排色度不同的啤酒摆在架子上，很是好看。根据色度不同，啤酒可以分为淡色啤酒、浓色啤酒和黑啤酒。
四、泡持性
      泡持性是指啤酒泡沫所能维持的时间，是评价啤酒的一个非常重要的指标。测量啤酒的泡持性通常采用“秒表法或仪器法”，以秒计量，测量时需要用专用的测量杯测定，普通杯子不符合要求。根据国际规定，优级啤酒的泡持性应该大于等于180秒，一级啤酒泡持性大于等于130秒。

除以上四个指标外，评价啤酒品质的专业指标还有很多，例如发酵度、酸度、苦味值，等等。今天我们只聊这四个比较通俗的。啤酒的质量不是某一个方面能够决定的，它是一种综合考量。不同风味啤酒判断指标的标准值也有所差异。相信随着精酿啤酒行业的发展壮大，会有越来越多的人懂啤酒，也会有越来越多的酒坊能够酿造出品质上乘的啤酒！

It seems hard to deprive engineering pursuits of the romance that is often attached to the business, and bring it down to a matter of commercial gain; but it is best to deal with facts, especially when such facts have an immediate bearing upon the general object in view. There is no intention in these remarks of disparaging the works of many noble men, who have given their means, their time, and sometimes their lives, to the advancement of the industrial arts, without hope or desire of any other reward than the satisfaction of having performed a duty; but we are dealing with facts, and no false colouring should prevent a learner from forming practical estimates of practical matters. 2. The percussive force of spouting water can be fully utilised if its motion is altogether arrested by the vanes of a wheel. The names of many priests will be found in the register of Belgian martyrs. I have mentioned already some who, although innocent, gave their life for their country. During my week's stay at Louvain I heard of other cases. The priest of Corbeek-Loo, for example, was simply tortured to death on account of one of his sermons in which he said that the fight of the Belgian army was beauti142ful "because it lawfully resists an unlawful invasion," and further for announcing a Holy Requiem Mass for the souls of the "murdered" citizens. I have been able to assist a good many of these unfortunate people by bandaging the wounds with the dressing they gave me, or getting some water for them from some house in the neighbourhood; and one, who had fallen down exhausted by pain, I carried into a house. 84 They thought very well of the idea. There were two rooms to the cabin where they were, the big sitting room and the small bedchamber beyond. Kirby went into the bedroom and came out with two rifles and a revolver. He put the revolver into his wife's hands. "I'll do my best, you know, dear. But if I'm done for, if there is no hope for you and the children, use it," he said. And added, "You understand?" "Shorty's all right if he don't get a setback. The danger from the blow on his head is pretty near past, if something don't come in to make further complications. He has been pulled down pretty badly by the low fever which has been epidemic here since we have settled down in camp, but he seems to be coming out from it all right." "Where?" asked Si, running up to him. "Be patient," Shorty consoled him. "Your three years's only begun. You'll have lots o' chances yit. But if I ketch you shootin' at any more white birches I'll tie you up by the thumbs." "That reminds me," said Shorty, "that our squad o' recruits'll probably fill up the rijimint so's to give McBiddle his eagle. They'll be 'round presently to divide up the squad and assign 'em to companies. As all the companies is about equally strong, they'll divide 'em equally—that'll make six and one-half boys to each company. Capt. McGillicuddy bein' the senior Captain, is to have first choice. We want to pick out the best six and one-half for our company and put 'em in one squad at the right or left, and give the Captain the wink to choose 'em." "Respected Miss Maria, what a fine writer you are. Yore She ran out of the house. Away on Boarzell a man plodded and stumbled. She saw him stagger as the wind battered him, reel and nearly fall among the treacheries of the dead heather. He was like a drunken man, and she knew that he was drunk with shame. "And have not I," said Turner, whom an extra cup had made more than usually a braggart; "Have not I forged as many spear-heads as ye can find handles for? and has not John Tickle, the London doublet-maker, made me sixty as stout leathern doublets as man could wish to wear? and can I not bring the tough sinews of the brave Kentish men to strike down the hirelings of that foul council which has brought all this misery on the people?—and will ye talk of your pitiful gifts? Am not I the right hand of the prophet?——" HoME ai人体艺术图片 ENTER NUMBET 009www.fcdz.org.cn
