Jack's Stir Brew Coffee

I needed a cold brew with a kick to give me life after a classics too much fun in the Hamptons night and Jack’s delivered. It was strong, fresh, cold, and delicious. Oh and talk about plenty because this thing was big. I unfortunately did not have an appetite because #hungover but this cold brew brought me back to life. I’ll be back to try some of their vegan bakery items.

No hot food at this location. Only pastries. Website menu shows oatmeal. Brewed coffee was good. Smooth on the dark side with caramel notes. Basically, a take out shop.

I stopped at Jack's for the first time after a long drive and tougher than usual day. Delicious treats and my cappuccino was perfect. Thank you Veronica for your outstanding service and smile to turn my day around. I bought some coffee to serve at my airbnb and know the guests are going to love it!

Jack's coffee is consistently sour by all objective measures. (Tried it twice in 6 months.) Mentioned the sour taste to the person working there and got the polite reply, "no it's not". But, yes, it is. If you don't mind sour coffee, Jack's is the place. If you don't, save your money. The pastries are good, but if not to your liking, the bakery next door is great . . . . and so is their coffee.

Get the Jack's Coffee Thermos. I bought a hot coffee this morning at 8:15 and it is now 1:30 and the coffee is still warm. Granted it's not the freshest brew, but that's my fault! Go get this thermos.... And Jack's is a great coffee shop as well... : )

So cute on the inside, with a very friendly staff. Great cold brew and other coffee, though it is on the expensive side if you aren't used to Sag Harbor prices.

Have two spots to buy online never works are you even open

Favorite place in sag for a cappuccino.

Excellent coffees, nice vibe, pricey pastries but yummy

Has options for all dietary restrictions and has amazing coffee that is way vetter than Hampton coffee company or starbucks
