Tips for Using a French Press With Borosilicate Glass

Using a French press made of borosilicate glass can be simple once you know some tips to get the most out of it.

Brewing techniques are important when using a French press. For starters, make sure that the coffee grounds are ground to a coarse consistency. This will prevent them from passing through the mesh filter and ending up in your cup.

When pouring the boiling water into the carafe, make sure not to overfill it so there is enough room for stirring. Once all of the water has been added, use a spoon or spatula to stir vigorously for 30 seconds before pushing down on the plunger. Doing this will evenly disperse the coffee grounds and ensure that every cup tastes great!

When you’re ready to pour your coffee, do so slowly and carefully as there may still be some hot water left at the bottom of your French press carafe.

Additionally, cleaning your French press between uses is paramount for maintaining its longevity and ensuring each cup of coffee tastes just as good as the last one! To clean it, remove any remaining grounds and rinse with warm water before allowing it to dry completely before storing away again until next time.
