What to Do if the Shot Tastes Sour

If your shot tastes sour and feels thin or watery, it's likely under-extracted—meaning the water didn't spend enough time pulling flavor from the coffee. This often happens when the shot runs too fast. To avoid this...

Adjust Your Grind Setting Finer

Try making your grind slightly finer to slow the flow and increase extraction. 

Make Sure You're Using the Appropriate Profile for Your Roast Level

Different roast levels have ideal brewing parameters. Series 1 includes Shot Profiles specifically tailored for light, medium, and dark roast coffees. Selecting the right profile for your roast is the simplest way to ensure you're on the right track to dialing in your specific coffee. You can switch profiles in the app or on the machine by going to the profile and selecting "Make active".
