Breville BCG820BSS Smart Grinder Pro for Coffee and Espresso, Brushed Stainless Steel

I recently bought a Breville Smart Grinder Pro BCG820 in November 2025. This was to replace the same grinder I had bought in September 2015, which lasted almost 10 years. This type of grinder was necessary to produce a fine grind, required for espressos made in our Breville Dual Boiler machine (BES900/B). After 10 years, we found that the original grinder was no longer producing a consistent, fine grind as it had previously. We followed all the normal trouble-shooting advice, including doing a thorough cleaning of the conical burrs. It was not until removing the lower burr and examining it carefully that we realised that the "teeth" had actually worn smooth with 10 years of use (3 times a day). This meant that there was actually a perfect "seal" such that any ground coffee could not actually exit the grinder. We are happy with our replacement purchase and look forward to another 10 years of use. With hindsight, we could have probably tried harder to secure a replacement lower burr set for the original grinder and just replaced the worn-out lower burr set. Incidentally, we use this grinder with the Breville Dual Boiler machine which we bought in 2013. We had the Dual Boiler machine serviced in 2019 by a company recommended by Breville (in St Peters, Sydney). It is worthwhile getting such a service, which, even though relatively expensive, is cheaper than buying a new machine (and less wasteful). At the time we bought the Breville Dual Boiler machine (in 2013), Breville was offering a complimentary barista course with Toby's Estate. This was incredibly worthwhile, to get the most out of the machine, since Toby's Estate was running barista courses with a room full of Breville machines at the time.
