Uhoh! This doesn't sound right!
We're sure we can help you in getting the best taste out of your coffee. A few questions to consider. Possibly the season has changed and your current grind setting is just not quite right with the aging process of your beans now. Try changing the grind setting more courser/finer to get the extraction back to its best!
Make sure you're storing your beans in an airtight container, away from sunlight in a cool area (your cupboard is just fine).
You may need a recipe to give you an indication as to what is the best extraction time for your machine.
Please send an email to firstname.lastname@example.org together with the batch number and roast date (just in case) and we will hand the info over our production team.
Please note: If you have a Breville machine at home and are with the white glove service, we recommend giving them a quick buzz and taking advantage of this service. They will be able to troubleshoot for you and provide the best feedback and recipes on the machines.
