Party Donut

Cakes are fine, but a donut the size of a spare tire is obviously better. We make giant custom brioche donuts for any occasion. Just give us a call two days in advance and we'll make all of your wildest dreams come true.

About Grindstone

Open year-round in Sag Harbor since 2016. We make fresh brioche and cake donuts daily, using only the finest ingredients. Our small batch process takes two days to complete, but when they're done, you know you have something special. Our glazes and fillings are all made in house from locally-sourced organic ingredients.

We take our coffee just as seriously. We sell and brew premium coffee from local and nationally recognized roasters, prepared by our highly skilled barista staff. A full espresso menu, specialty teas, and a never ending supply of cold brew will be the perfect compliment to any box of donuts.
