国外美女视频手把手叫你如何做虹吸式
The vacuum pot, also called the syphon, is a beautiful and flashy way to make great coffee. Invented in Germany in the early 19th century, it's a full immersion brewer that also employs a metal or cloth filter, so you end up with a full-bodied and clean cup. This brew method can be rather finicky, but with some practice can certainly be mastered.
虹吸壶—— 华丽而美好的冲泡方式。19世纪由德国人发明，采用完全浸泡的冲泡方式，使用金属或者织布的过滤器，冲出的咖啡非常醇厚，喝完后杯子也不会有杂质。这个冲泡方式非常讲究细节，可以通过不断的练习慢慢掌握到精通。
虹吸式咖啡制作过程
Step 1：Prep filter
Pull the chain of the metal filter attachment down and sink it. The clip attaches at the bottom of the funnel.
首先把滤布洗好系在金属片上，然后把小圆珠子穿过上壶的玻璃管，向下拉，知道小勾子勾住玻璃管下方。
Step 2：Add water
Use pre-heated water to make things move a lot quicker when brewing. Make sure the outside of the globe is completely dry before you apply heat to prevent it from cracking. Fill the globe to the No. 5 mark.
使用已经加热了的水省去加热的时间，加热前确保圆形的下壶外面是干燥的，加水加至水位5。
Step 3：Apply heat
Vac prts usually come with a candle burner, but a butane burner (shown here) is much more effective. Turn the burner on and up high. Loosely place the funnel inside the globe so it sits at an angle while you wait for the water to boil—boil times vary.
虹吸壶一般用蜡烛加热，但丁烷燃气（即瓦斯，如下如所示）更加有效，打开燃气，调到最大火。
Step 4：Measure and grind coffee
Measure out 40 grams (about 6 Tablespoons) of coffee. Grind coffee to a medium coarseness or about as fine as table salt.
测量40g咖啡豆出来进行磨粉，磨成中粗粉，像食盐般粗细。
Step 5：Attach top
Once the water starts to boil, attach the top funnel securely to the globe.
水一旦开始沸腾，就可以把上壶竖直牢牢插入。
Step 6：Add coffee
When the top assembly fills (you'll want a little water remaining in the globe), create a whirlpool and add the coffee directly into the water. Start a count-up timer.
当水上涨到上壶时（还有些许水在圆形的下壶）用搅拌棒在上壶穿着一个小漩涡然后直接把咖啡粉倒入，然后开始计时。
Step 7：Turn down the heat
Adjust your burner to lower the flame. Give the mixture a stir, immersing the coffee completely. At: 40 seconds, stir it again. This second stir is more of a gentle fold, making sure everthing is completely saturated.
把火调小，用搅拌棒搅拌一下上壶，使咖啡粉完全浸没，在40秒时，在轻轻的搅拌一次，确水和咖啡粉完全融合。
Step 8：The draw
At 1:30, turn the heat off completely and give it a big swirl. Wait for the coffee to draw down through the filther into the globe, which should be finished at approximately 3:00.
在1分30秒时，关火，旋转搅拌，然后等待咖啡吸下降回到下壶。整个过程月3分钟。
Serve and enjoy！
TIPS
- 一开始使用虹吸式咖啡壶最常见的失败点，就是“火力太强”，所以控制好火焰的大小均匀是很重要的。
- 牢牢固定滤布，没有吧滤布固定好的话，一定会惨遭失败，要压住滤布的中心，彻底按压好后再拉紧套牢，确定不会松开。
- 搅拌力度要轻柔，为了让咖啡粉和热水充分融合，必须要用木棒搅拌，但搅拌过头会导致萃取过度，形成咖啡的杂味，重点是轻轻的慢慢地搅拌。
- 要注重虹吸壶的存放和保养工作，使用完后里外都要清洗干净，泡在装有水的容器中冷藏，如果2~3天都没有使用，请先加以沸煮后再使用，另外如果使用时咖啡不会滴落，说明滤布阻塞。
