Brew Temperature Analyzer (BTA) for E61 Group Coffee Machines

Introducing our Brew Temperature Analyzer (BTA), a compact, easy-to-use measurement tool designed specifically for home baristas. It accurately tracks the temperature during the coffee extraction, giving you full control to perfect your espresso brewing temperature.

Built with a high-precision Type T thermocouple, it delivers real-time data with minimal setup, allowing you to determine the brewing temperature inside your coffee basket. The Brew Temperature Analyzer offers the accuracy and feedback typically reserved for commercial tools - now in an affordable, user-friendly format.

Why should you use the Brew Temperature Analyzer?

• Determine the true brewing temperature and correct the machine offset value
• Measure the machine heat-up time until stable operating temperature is achieved
• Analyze the shot-to-shot temperature stability of your coffee machine

How to perform the temperature offset measurement?

To achieve optimal measurement accuracy and repeatability, it is recommended to perform the tests based on a temperature measurement protocol. Two valuable resources for espresso machines are:

• Competition Espresso Machines: Specifications & Test Methods (2021 Edition) by the Specialty Coffee Association (SCA)
• Espressomaschinen-Testprotokoll (in German) by Kaffeemacher

How to calibrate your temperature sensor & reader?

It is recommended to calibrate your sensor and reader setup before your first temperature test to guarantee the best measurement accuracy. A video tutorial on how to calibrate your device will be available soon.
