How does he get his coffee fix ? At work ? A connoisseur knows that decoction does not store well. Coffee is an anti-oxidant, id est, it is anti to any oxidant it comes across -- like oxygen in the air. In the process coffee becomes oxidized and tastes bad. In these modern days of refrigeration (in a tightly closed glass bottle) one can extend the life of taste. Or it can be frozen into icy chunks and reused a day later.
