Have you checked out our cozy East Hampton location yet?! There's a cute little patio with tables out back to relax while you enjoy your donuts and coffee, gifting goods to buy for people you love, beautiful flowers to see and smell and the best smiles from Otto, Kieran, Tina and the crew! 🍩

The process 🤝 It’s an every day grind. We get up at 2am to be making your fresh brioche & cake donuts by 3am daily until they’re freshly delivered to both for our locations & our friends over at Amagansett Coffee Co. before 7am. We also produce our own homemade biscuit Bacon Egg & Cheeses in small batches.

Our team has been working this hard for over a decade. Hundreds of thousands of donuts later - a donut love story between the community of Sag Harbor, East Hampton and beyond. Pop in and grab a donut! 🍩 Sag Harbor Chamber Of Commerce

You know the Grindstone way of life... it's a perfect morning when you walk in and grab a BEC on our homemade biscuit or a Passionfruit Guava custard filled Brioche donut. Honey lavender iced latte, dirty chai, iced Mocha... The choice is yours. No - literally... we have two locations silly. ☺️

Go say hi this week to Tina or Sof at the East Hampton or Sag Harbor locations! 🍩
