Beans that are recently roasted will produce more crema, but normally this settles down after a week or so. Darker roasts also produce lots of crema too, unions revelation is pretty dark so I would expect heaps of crema with that bean like you describe. There is no amount of crema that is too much, it's just a characteristic of the bean and how it's been roasted. Crema actually tastes pretty awful (spoon a bit off and taste it yourself, it's super bitter) so you might notice your shots taste better if you scoop the excess crema off after the shot has settled.

 

If you float out the kitchen door on a raft of crema, then it's too much....Leave the coffee a week or so and you will get less crema.

 

Thank you both - good advice and you have improved my coffee knowledge!

 

Whilst we're at it then, it's also possible to weigh the shot with scales, rather than basing it on a volume of liquid. As you and the others mention crema is variable so you might actually change the shot quite a bit if going based on the volume.

for which you can pay £6 to £200 depending on your requirements....personally I would keep it down into the £6-£9 mark unless you have money to burn.

@DavecUK can you link those scales you use in your vids?

 

This is why you stop a shot by weight not by volume ....

I can, but sadly they no longer make them any more and they have become unobtanium everywhere you look. I am so glad I purchased an extra spare pair for £9 last year.
