咖啡的沖煮基本常識

1. 用新鲜水煮(一定要经过过滤)且要完全煮沸。

當咖啡粉浸泡在沸滾開水裏時，開水的溫度會降低到約90度左右，再過濾到咖啡壺時會變爲85度左右。加了砂糖和牛奶以後可喝時的溫度差不多是60度，也就是咖啡的味道最可口的適當溫度。爲了保持咖啡的這個適當溫度，最好是把咖啡壺和咖啡杯事先加熱保溫。

2. 大约在三分钟内就要冲泡好。

美式咖啡壺濾泡的時間太長或太短都會影響咖啡的味道。濾泡的時間短則泡不出味道來，濾泡的時間過久，則味澀而粉末味重。不要一次泡過多再來溫熱，泡過後用保溫器保溫二十分鍾左右，還能保持可口的味道。

3. 单品咖啡的咖啡粉单人份适当泡量是15克。咖啡粉的分量过多时泡出来的味道又酸又苦而失去了甜味。如果水量过多就淡而无味。一人份的咖啡是15克，开水一人份120cc，三人份要50克冲360cc。

◎沖泡咖啡之前，要有好水來配

新鲜的水经过煮沸后,会含有适量的二氧化碳可以增加咖啡的香味,但持续让水沸腾会令二氧化碳素蒸发减少,所以最佳的水温是92℃,水温太低会使咖啡味道无法完全释出, 水温太高会让咖啡成分变质,过多与不及都是不好的。

◎咖啡的保溫及保存

要维持咖啡的温度, 可以先将盛咖啡的杯盘加热,喝剩的咖啡可以把咖啡壶泡在热水里保温,放在开水里煮可以确保咖啡热度维持在最佳状态.如果将咖啡壶直接放在瓦斯炉上加温,要注意不要煮沸,咖啡一但煮沸某些成分会起化学变化,酸味会变强且损坏原来香味。

"We walked by the side of our teams or behind the wagons, we slept on the ground at night, we did our own cooking, we washed our knives by sticking them into the ground rapidly a few times, and we washed our plates with sand and wisps of grass. When we stopped, we arranged our wagons in a circle, and thus formed a 'corral,' or yard, where we drove our oxen to yoke them up. And the corral was often very useful as a fort, or camp, for defending ourselves against the Indians. Do you see that little hollow down there?" he asked, pointing to a depression in the ground a short distance to the right of the train. "Well, in that hollow our wagon-train was kept three days and nights by the Indians. Three days and nights they stayed around, and made several attacks. Two of our men were killed and three were wounded by their arrows, and others had narrow escapes. One arrow hit me on the throat, but I was saved by the knot of my neckerchief, and the point only tore the skin a little. Since that time I have always had a fondness for large neckties. I don't know how many of the Indians we killed, as they carried off their dead and wounded, to save them from being scalped. Next to getting the scalps of their enemies, the most important thing with the Indians is to save their own. We had several fights during our journey, but that one was the worst. Once a little party of us were surrounded in a small 'wallow,' and had a tough time to defend ourselves successfully. Luckily for us, the Indians had no fire-arms then, and their bows and arrows were no match for our rifles. Nowadays they are well armed, but there are[Pg 41] not so many of them, and they are not inclined to trouble the railway trains. They used to do a great deal of mischief in the old times, and many a poor fellow has been killed by them." The boys looked in the direction indicated, but could see nothing. This is not surprising, when we remember that sailors' eyes are accustomed to great distances, and can frequently see objects distinctly long before landsmen can make them out. Mr. Charlton's melancholy eyes seemed to be fixed on space. Just for the moment he had forgotten that he was not alone. Lawrence gave a sympathetic cough. As a matter of fact, he had not yet explained what he was doing there, and the longer the explanation was postponed the better he would be pleased. "You see our patient has gone," Balmayne said smoothly. "As a matter of fact, the whole thing was a ridiculous mistake. But you must not blame us. The blame is due to the charming young lady who sent for you. But that is one of the drawbacks of your noble profession. Goodnight." In one of the inmost circles, a sacred elephant had gone must, breaking his ropes, and confined now by only one leg. The chains fastened round his feet as soon as he showed the first symptoms of madness were lying broken in heaps on the ground. The brute had demolished the walls of his stable and then two sheds that happened to be in his way; now he was stamping a dance, every muscle in incessant motion, half swallowing his trunk, flinging straw in every direction, and finally heaping it on his head. A mob of people stood gazing from a distance, laughing at his heavy, clumsy movements; at the least step forward they[Pg 113] huddled back to fly, extending the circle, but still staring at the patient. In an adjoining stable were two more elephants very well cared for, the V neatly painted in red and white on their trunks, quietly eating and turning round only at the bidding of the driver; but one of them shed tears. The rajah's sleeping-room has at one end a dais ascended by three steps; here the sovereign's bed used to be spread; and here, now, the judges of the Supreme Court have their seats. In the middle of the room was a confused array of benches and tables, and against the walls, also washed with yellow, hung a series of portraits of bewigged worthies. No new clues offered themselves. He detached one of the hard, adhering chunks of gum and dropped it into his pocket, “just in case,” he said, half-grinning, “just in case they transfer themselves somewhere else. I’ll leave twenty-nine of them—and see.” The Lieutenant and Si and Shorty tried to make themselves believe that the noise was receding, showing that the rebels were being driven. At times it certainly was so, and then again it would burst out, Naturally, the boys were big-eyed all the time with the sights that filled the landscape near and far. Wherever they looked they were astonished, and when in a march they came out on a crest that commanded a wide view, they could not help halting, to drink all its wonders in. Even the experienced Si and Shorty were as full of amazement as they, and watched with fascination the spectacle of mighty preparation and concentrated power. "It has a great deal to do with this lecture with which you have favored us," answered the Major dryly. "But we'll not discuss that in open court. Are you through with the witness, Judge-Advocate? If so, call the next." "But I'm not going to leave you alone to brood," Albin said. "Because I'm your friend. And brooding isn't good for you. It's brooding that's got you into such a state—where you worry about growing things, for God's sake, and about freedom and silly things like that." Albin grinned. "What you've got to do is stop worrying, and I know how to get you to do that, kiddo. I really do." "Where may I learn the others?" But Gornom didn't answer, and Cadnan's breathing-space was over. He had to be back at the board, pushing buttons, watching carefully. Gornom stood behind him, peering over his shoulder with a cloudy eye. Neither said a word until the new spell of work was over. Then Cadnan repeated his question. He had become separated from the other searchers, and was alone on the west side of the Moor. The wind barked and howled, hurling itself upon him as he stood, beating his face with hail, which hissed into the dead tangles of the heather, while the stripped thorns yapped and rattled, and the bushes roared. So great was the tumult that he seemed to fall into it like a stone into a wave—it passed over him, round him, seemed even to pass under him, he was hardly conscious of the solid ground. The blackness was impenetrable, save where his lantern stained it with a yellow smudge. He shouted, but his voice perished in the din—it seemed as if his whole man, sight, voice, hearing, and sensation, was blurring into the storm, as if Boarzell had swamped him at last, made him merely one of its hundred voices, mocking the manhood which had tried so much against its earth. While the guide paused for a moment to recollect the way to the head-quarters of the insurgents, some one who passed was heard speaking in a tone which fell upon Stephen's ear like a sound he ought to remember; he sprang from the side of his comrades, and, standing before the strangers, demanded, "With whom hold you?"
