The coffees in this bundle are available only as the pair and for a limited time only.

At this year's Swiss Coffee Challenge, Baristas were faced with an array of different challenges involving all skills of coffee making and one of them was to serve an espresso using a blend of two single origin coffees provided. As the chosen roaster for the Coffee Challenge Espressos, we roasted two very different coffees for the participants, each one having very unique and different characteristics: A high grown and washed processed Arabica from Eastern Africa and a lower grown natural processed Canephora from Central America:

Coffea Arabica: Rwanda Nyaruzina Lot 76 washed Red Bourbon

Coffea Canephora: Ecuador Asochakra PB natural Napa Payamino

We were curious to see how they would be combined to make the whole more than the sum of its parts. The teams chose very different blending and brewing ratios:

Team Kaffeemacher:innen (Dario & David)

60% Ecuador und 40% Rwanda

18.5g in, 45g out in 22s

Team GOAT's (Chris & Daniel)

75% Ecuador und 25% Rwanda

21.5g in, 35g out in 29s

Team Adrianos (Vanessa & Jonas)

10% Ecuador, 90% Rwanda

18g in, 48g out in 22s

Team Giovanna and Matt

72% Ecuador, 28% Rwanda

18g in, 45g out in 15s

Team Henauer (Dario & Philipp)

8% Ecuador, 92% Rwanda

18g in, 50g out in 27s


So now here's your chance to try each of these coffees on its own, create a unique blend or follow the competitor's recipes to see for yourself what's the best way you like your espresso.
