This, shockingly enough, isn’t about espresso. It is about brewed coffee, and the fact that brew temperature is completely wrecking my head. We talk a lot about brew temperature but what we are really talking about is water delivery temperature.
I love my Uber boiler, I love the control and the delivery temp stability. With this, however, has come the painful and embarrassing realisation that it doesn’t matter. Alright, that is perhaps an overstatement – temperature has massive influence on the quality of the brew, that is undeniable. I may love the control of the Uber, but having a consistent and controllable temperature really just shifts the problem from the exit spout to the vessel underneath.
