Why Does Chemex Have A Wooden Collar And Leather Rope? 

Chemex prides itself on the design of its brewers. 

The brewers are all made from durable and heat-resistant glass, with slight variations in the design of the handles. The most common models come with a wooden collar and leather rope. 

While some argue this is merely a style element, these two elements do serve a practical purpose. 

The wood is heat resistant, so you can handle the coffee flask when it’s filled with hot water. The leather ropes hold the two pieces of wood in place.

What Kind Of Knot Is Used On Chemex?

A knot is a knot, and regardless of the type used, they all serve a similar purpose, right? 

Not quite. 

Chemex uses a square knot. Mainly because it effectively holds the pieces of wood in place and it’s easy to undo. 

Because the square knot is a binding knot, it means you’re less likely to get irritated over the ropes unfastening mid-brew. 

This style also works for curved surfaces. And because the wooden pieces are curved, it functions brilliantly.

How To Disassemble Your Chemex For Cleaning 

To ensure the wooden collar keeps its shape and color for a long time, you should separate it from the carafe in time for cleaning. Here are two simple steps to disassemble your brewer. 

  1. Untie the string.
  2. Loosen the rope enough to slip over the carafe.

The collar should fall apart in two pieces. Now you can wash your carafe.


Tying the ropes of your Chemex brewer makes it easier to handle your carafe when you’re brewing and pouring your coffee. 

The knot used on the Chemex is the square knot (reef knot). It effectively holds the two pieces of wood together and it’s simple to untie. 

Tying the knot is as easy as tying your shoelaces. Besides the visual appeal of the leather rope and wooden collar, having a firm collar in place means you don’t burn your hands when pouring your morning coffee.
