What makes a coffee strong?

Mocopan Coffee’s Babin Gurung on what coffee strength means and how to achieve it.  During my barista hustling days, customers often told me they liked their coffee strong.

Reflecting on her journey, she stresses “water plays a gigantic role, but there is much left to discover. Working with water opens up lots of questions”.

How brew water temperature effects espresso extraction

Dr. Monika Fekete investigates the chemical and sensory effects of different brew water temperature on espresso extraction. Do you feel like a refreshing cold brew in the summer heat? Or what about an iced latte? Whichever you prefer, there are a range of factors that contribute to their unique tastes, and the temperature they are prepared at is certainly a big one. While it’s easy to appreciate the difference between cold and hot brewed coffee, it takes careful investigation to dissect how fine-tuning brew water temperatures can affect physical and sensory outcomes.

How minerals modulate taste and their role in extraction

A truly outstanding brew depends on many factors falling into place at once. Carefully chosen and roasted beans need to work harmoniously with matching water and a strict brew method to extract and highlight desired flavours. Increasingly, brewers are focused on the impact water has on taste outcomes. According to 2017 World Brewer’s Cup Runner-up Sam Corra, one of the most important factors to brewing an amazing coffee experience is having a brew water that will best represent a coffee’s attributes. He notes, however, that one water formulation will not necessarily suit other coffee varieties, processes, and origins.
