This post is really a question, with some initial answers coming soon. After getting the idea from Josh of Seattle Coffee Works, I've been thinking about the possibilities of brewing multiple coffees simultaneously in a single press.
It's always been possible to mix beans or grinds from different coffees and throw them in the press. The Coffee Catcher may make it possible to layer and adjust that brewing process to bring out the best in both coffees. Blending is not tried often, and for good reason. There are many ways that this could go horribly wrong from a flavor perspective. That said, the possibilities of brew layering are fascinating, including tweaking temperature profiles down the press, incorporating a pour over effect involving multiple coffees, adjusting grind size for different brewing conditions, and even adjusting brew times separately.
I don't know if this would work. I'm still looking for a pair of interesting coffees that I want to combine in the press using two Coffee Catchers. Any suggestions?
Bonus Question: What would we taste if the separate components of an espresso blend were brewed this way?
