The lab currently has a DeLonghi Magnifica ESAM 4200.S bean to cup espresso machine.
Coffee from this machines costs 50p.
The coffee being put in the machines at the moment is Lavazza Rossa.
The lab also stocks Fritz Caramel Coffee. This is a bottled drink with lots of caffeine and sugar and seems to be pretty popular. I think it tastes something like liquid coffee cake, or maybe coffee with biscoff dissolved in it with a lot of sugar.
If you are interested in coffee (or tea, mate, food, …), some people are trying to start a hacker cafe. Talk to River or Shell if interested.
