It’s been an epic adventure so far! We opened Grindstone in 2016 with a vision of creating the best damn donuts on Long Island and we think we’ve succeeded. Thousands per week for a decade really makes you think how far we’ve came. From making all the donuts in Sag Harbor store back room to our now full prep kitchen operation! 🤝

So excited for the future and all the new happenings at both locations. Come in and say hi to us this Summer! Make sure to grab a donut. 🫶 🍩
