Breville’s grinders to a fine job with medium to darker roasted coffees. However, they're not as good when it comes to lighter roasted coffee as you need more control when grinding these as they're more temperamental beans. But for the person looking for an all-in-one option, and wants to enjoy classic cafe coffee, they do the job well. If you want to drink lighter roasts, or think your Breville will be a “stepping stone” machine, then you’re better off getting a Breville machine without a grinder built in.
