How does it affect the brew head?

It's a topic that baristas argue about very often! ☕️⚙️ In conclusion, "Should Portafilter be plugged in the coffee handle to the brew head?" Today we'll summarize the right advantages, disadvantages, and practices to make the coffee delicious and the machine slow down!

🌡️ Why hold down the brew handle? (Advantage)

The main reason is "temperature," because the metal handle, if it is cold, will become a good endotherm!

- Prevent Cold Sink. If the handle is cold, it will suck the heat from the water flowing through it while extracting. This makes the water drop. The resulting coffee will taste distorted.

- Consistency. Keeping the brew handle warm with the machine will reduce temperature fluctuations, resulting in a good-tasting espresso with beautiful Crema.

- Very important for machines without PID. The machine does not control the temperature accurately. It depends on the heat accumulated in the handle to help reinvigorate the extraction temperature.

⚠️ Cautions and potential adverse effects

There are heat advantages, but if you do not do it the right way, you can also have serious consequences:

1. Rancid and fungal smells. If it is skewered, either with coffee grounds or accumulated moisture, the heat will become a bacterial and fungal culture. Make the coffee water next time smell rancid.

2. Gasket wear quickly. If we turn the handle into the brew "too tight" while not brewing, the pressure will cause the brew head rubber seal to be crushed all the time until the tire deteriorates, hardens and causes water to leak on the edge of the brew.

✅ Correct practice: clean + warm + loose

If you want the hot handle to be ready to use but the machine does not break, this is recommended.

1.Knock and wipe immediately. After the brew is done, knock out the coffee grounds and wipe the brew handle clean and dry immediately.

2. Put it back loosely. Put the brew handle back in the brew head to keep the heat up. But "just enough spin" does not need to lock it tightly to reduce the pressure on the rubber gasket.

3. Clean the brew head often. Don't forget to flush the water and scrap the coffee on the shower screen before putting the brew handle back in.

In summary, leaving the brew handle on the brew head is good for the coffee taste. "If you clean it and don't lock it too tightly"!

... Read moreนอกจากการรักษาอุณหภูมิด้ามชงกาแฟให้คงที่แล้ว การเลือกใช้อุปกรณ์เสริมอย่างเข็มเกลี่ยผงกาแฟก็มีผลต่อคุณภาพรสชาติไม่น้อยครับ ผมเคยลองใช้เข็มเกลี่ยในช่วงที่ต้องการความละเอียดตรงในการเตรียมผงกาแฟ พบว่าช่วยให้เนื้อผงกาแฟแตกตัวสม่ำเสมอ ลดปัญหาการสกัดที่ไม่สมบูรณ์ได้ดี อย่างไรก็ตาม การใช้เข็มเกลี่ยต้องระวังไม่ให้ผงกาแฟถูกกดหนักเกินไป เพราะจะทำให้กาแฟเสียรสซึ่งละเอียดอ่อนง่าย ใครที่ชอบชงกาแฟเองที่บ้านหรือเป็นบาริสต้าก็ควรฝึกเทคนิคการใช้เข็มเกลี่ยผงกาแฟเพื่อให้การสกัดออกมาดีที่สุด นอกจากนี้ ข้อมูลที่ผมศึกษาจากหลายแหล่งยังชวนให้ระมัดระวังถึงผลข้างเคียงจากการดูแลสุขภาพด้วย โดยเฉพาะเรื่องจตุผลาธิกะซึ่งเป็นผลข้างเคียงของสารบางอย่างที่อาจมากับกาแฟบางชนิดหรืออุปกรณ์บางประเภท อย่างไรก็ตาม ในการชงกาแฟทั่วไป การรักษาความสะอาดของอุปกรณ์ชงกาแฟ เช่น การล้างด้ามชงและหัวชงอย่างสม่ำเสมอ จะช่วยลดโอกาสปัญหาเหล่านี้ได้มาก สรุปคือ ถ้าใครต้องการชงกาแฟรสชาติดี ควรศึกษาเรื่องการรักษาอุณหภูมิของด้ามชงกาแฟ ใช้อุปกรณ์ช่วยอย่างเข็มเกลี่ยอย่างเหมาะสม และไม่ลืมความสำคัญของสุขอนามัยในกระบวนการชง ก็จะได้กาแฟที่อร่อยและรักษาเครื่องได้ยาวนานครับ
