Resting Coffee Period
Did you know that coffee needs to rest for at least a day after roasting before its flavours fully emerge? Like red wine needs to breath after opening, coffee needs to rest for
Tasting is very, very context sensitive
The sequence of tasting coffees has a remarkable impact on the perception of taste. Just like in music, certain notes together can be dissonant while apart they can be beautiful, coffee flavours can clash or compliment. We have learned to try coffees in various sequences to verify our experience of the coffee.
Brewing Temperature is Remarkably Important
We recently had a technical problem with the brewer at the cafe that caused it to brew to hot by about 5 degrees F. It scorched the coffee to the extent that we held off launching a new coffee until the brewer was repaired and re-calibrated. The coffee was over-extracted, unbalanced and somewhat bitter. The same coffee brewed at the correct temperature (we use about 200F) is balanced, smooth and pretty.
At the other end of the spectrum, brewing at a lower temperature results in under-extraction that tends towards sour undeveloped flavours.
