棕榈篡改与普通篡改：一个比另一个好吗？
Tamping seems like such a simple concept. But then why are there so many different espresso tampers? Palm tamper, calibrated tamper, original tamper – no wonder you’re confused!
Does one type of espresso tamper reign supreme? Or do different situations call for different devices? Read this palm tamper vs regular tamper showdown to find out.
Palm Tampers
Palm tampers, also sometimes called puck tampers due to their appearance, have a simple look that belies their clever design. They are calibrated to tamp to a certain depth, which you can set to match your dose using an adjustment mechanism.
优点：
-
Perfectly consistent
-
Guarantees a level tamp
- Ergonomically healthy for the wrist
缺点：
-
Inconvenient if you regularly change your dose
- No way of knowing the pressure
Regular Tampers
Regular tampers come in two forms, original and calibrated (1）。An original tamper is a heavy metal disk topped with a handle, whereas a calibrated tamper looks similar but has a spring mechanism for setting a specific pressure. Regular tampers can have flat or convex bases.
优点：
-
Original-style tampers are inexpensive
-
校准的纹理器提高了一致性
- Huge selection of sizes and designs
缺点：
-
Calibration won’t stop you from over-tamping
- It doesn’t guarantee a level tamp
Features: Face-to-Face
With those basics covered, let’s get to the head-to-head showdown. We’ll compare the two styles ofespresso tampersacross three crucial categories.
Consistency
Tamping consistency is so vital that it’s one of our topespresso tips for beginners. There is no debate that the original style of the espresso tamper is the least consistent. It relies solely on practice and muscle memory to reproduce results. But between palm and calibrated tampers, the winner is less clear.
Palm tamper is set to tamp to a specific depth each time rather than a certain pressure. So as long as your dose is consistent, your tamp is consistent, and it also guarantees a level tamp.
Calibrated tamper is set to tamp a specific pressure to maintain consistency even when the dose changes. However, it is still possible to tamp with a higher pressure if you keep pushing past the spring’s set point, so it does take some practice. And most designs don’t guarantee your tamp will be level.
Winner:The palm tamper takes this round because it’s impossible to over-tamp and it ensures a level puck.
Ergonomics
Ergonomics may not be as important for the average coffee drinker使用浓缩咖啡机at home. Yet, for a commercial barista tamping hundreds of espressos a day, injury due to poor ergonomics is a real possibility (2）。用棕榈篡改，您可以用手掌直接向下推。带有常规的篡改，您可以抓住一个手柄，然后向下推。
Winner:棕榈篡改是一个明显的赢家，因为它可以使您的手腕处于更自然的位置。但是，除非您进行大量浓缩咖啡，否则您不太可能注意到差异。
Value for Money
Original tampers are the cheapest option, and if you’re a practiced barista confident in your skills, they provide excellent value for money.
Calibrated tampers were once a luxury item available from only a few brands, but lucky for espresso lovers, that is no longer the case. They’re now widely available in different sizes and prices. The fanciest run to $200, but mid-level brands like Normcore make fantastic options for under $50.
棕榈印仍然是相对新颖的产品，因此只有少数品牌提供它们。到目前为止，他们主要是高级品牌，这意味着目前它们相对昂贵，尽管这可能会改变。
Winner:The calibrated espresso tamper comes out on top, with the best combination of consistency and low price.
判决
Choosing the right tamper comes down to your budget, how you make your espresso, and how often.
Use a palm tamper if…
- You’re a barista preparing the same espresso all day long
- You never change your dose
- You are prone to wrist injuries
Use a regular tamper if…
- 您正在寻找省钱
- You change your dose frequently
FAQs
Channeling occurs when the coffee puck is uneven, so the pressurized water finds the easiest path through. You end up with a very fast, poorly extracted, and weak-tasting espresso.
一个加压的Portafilter迫使浓缩咖啡在高压下通过一个小开口。即使咖啡不足，它也会产生令人印象深刻的克雷玛，但缺乏全部风味。选择一个pressurized or non-pressurized portafilter研磨机的质量。
长期以来，正确的润肤压力已被认为是30磅，但最近已证明，水平的tamp甚至地面分布更为重要。一个好的经验法则是足够打击足够大的罐头，如果倒置，冰球不会从Portafilter中掉下来（3）。
