I put off buying a grinder for years as I was convinced that all the fuss and mess would mean I drank less coffee.
But then I found the perfect one. Iberital MC2 from Happy Donkey
It grinds and dispenses straight into the filter holder, so you don’t have any going stale, or over the worktop.
Mrs BigJohn likes hers a little weaker than me so I set the dispense so it’s 2 grinds for her and 3 for me. The grind settings can make it as fine or as coarse as you like. You tend to alter this with different beans which tend to grind differently.
A 100% improvement over pre-ground, and absolutely no faff or drawbacks.
£137 plus postage, and their own beans are rather good too.
And the machine I use is a Gaggia Classic.
