We recently got a very expensive Jura bean to cup machine at work - itās got 2 hoppers and grinders one for normal beans and one for decaf. It was over Ā£6k but I donāt use it - Iām not a fan of it at all.
One of our brighter colleagues filled the hopper up with instant coffee and wrecked one of the grinders which cost Ā£140 to replace - I was surprised at how cheap the replacement grinder cost given the cost of the actual machine itself, but I think that tells you all you need to know.
I bring in my own beans and use a Knock Aergrind with an Aeropress. The Aergrind was a cosmetic 2nd - the only issue I can find with it is that the zero point is a little past zero which isnāt a problem for me at all as Iām only using it with the Aeropress. It only cost me Ā£75 on Ebay direct from Knock themselves back in October
