I recently purchased a used NS Grinta from a local espresso joint. Turns out it needed new burrs. The place I found that offered an original set in Canada was out of stock and quite expensive regardless. Well, it turns out the Grinta 50mm burrs are the same burrs found on the Gaggia Baby and MDF! Italmill produces some and Stefano's has them in stock: https://www.espressocare.com/products/i ... aggia-baby.

If ever you were wondering, they fit perfectly in the Grinta!

If you are in doubt, change your burrs! It makes a huge difference!
