<p><strong>To keep the brewing temperature as stable as possible.</strong></p>

<p>When using glassware during brewing as in French-press, V60 or Chemex, it is important to warm up the gadgets prior to brewing. Normally, the water temperature is set just below boiling point (around 95 degrees Celsius) for a good brew. When you start with cold glassware, your nicely prepared close-to-boiling-point water may cool down a few degrees, which is crucial in the taste of the final cup of coffee.</p>

<p><em>Additional note:</em> Moreover, after brewing, pouring the prepared coffee to a cold cup may decrease the temperature a few additional degrees, which renders your beverage at most warm, instead of hot.  This is mostly visible in espresso as its volume is relatively small. As a result, it is also recommended to keep the cups warmed. Some home espresso machines have additional heating trays on top to keep the cups warm before pulling an espresso shot.</p>
