on letting the first bit of coffee from the
machine drain away rather than putting it into
the cup. I asked them about this and they claim
that the first flush is bitter and it's best to
let it go. Personally, I think it just makes
for a weaker cup of coffee, which is not a good
thing.
Opinions?
While I defer to the people on this forum when it comes to cycling matters, it seems that you may need a bit of education when it comes to coffee.
If you wanna get REALLY into it, you can head over to coffeegeek.comforumsOpen ↗ for hours of caffeinated amusement.
One theory on this is that, depending on the beans and the machine, the coffee in first few drops is not properly extracted and so can have a different flavour profile (often it can be more bitter) than the rest of the pour. After the first few drops (which should be dark brown / black), the pour should be brown crema for the next 25 seconds or so - this is the good stuff. Once the flow starts to become more pale you get over-extracted coffee, which is sour, so you really don't want this in your cup.
If you really want to tast the difference, ask your coffee shop to separate the first and second half of the pour (or, even better, to split it into thirds) into different cups and see what you think of each.
