If you're looking for great coffee, look no further! Best coffee around! The owner and staff are extremely friendly and the atmosphere is fantastic. Better than any chain! read more

I work at a bakery in Framingham, we supply Dave the owner with some bread and he gives us foils of coffee beans to brew for our staff and retail customers. He is a very nice guy, we meet at 6 in the morning when he picks up the bread and it is still dark out. Great coffee -- it has kept me warm and awake for several overnights of work. I will have to stop by the shop in sudbury sometime read more

Karma coffee is the best! I have been getting my beans from them since 2009. I have to say I recently tried a well known local roaster and it could not compare to Karma's roasts. There is something to say about their coffee, as well as the owner and staff. Great people and great coffee! I would highly recommend them. Many thanks to you all at Karma :-) read more

Amazing coffee! I got an iced latte, and I didn't need to put any sugar in it! I *love* when I find coffee that isn't bitter; it's so rare. I also had a slice of orange-chocolate chip almond torte. So moist, lovely! Next time here: again the iced latte was yummy, not bitter at all, no sugar needed. I tried one of the salty oat pecan cookies; nice! I like that saltiness, not overboard, just enough to enhance the flavor. read more

The real deal. Incredible espresso, they know what they're doing. I drive 20 minutes out of the way, each direction for this. I've traveled the country drinking coffee and this place does it right. Plus the employees are fun. Humble place, they could really expand and advertise and its blow up, but I think they like to be a hidden gem. Cold brews and almond milk lattes are my fave. read more

3.5 stars if I could. Hidden from the main road you would only know it's here if you managed to spot the small sign or like us were told about it by a local. A small non descript coffee bar which I can only assume they opened because they roast all the beans there. The place smells like just roasted coffee which is lovely. You can see the bags of unroasted beans and the machines from the shop. The people running the show were friendly enough however a little vague and all seemed a little like they weren't sure what was going on. I think someone was picking up and order and everyone was trying to figure it out rather than one person sorting it out and the rest of the people dealing with the other customers. The cappuccino was good, not great in my opinion though and served too hot-burnt my mouth So between the atmosphere of the shop (which there isn't any) the ok coffee and the too busy to pay much attention baristas it wasn't anything special. I'm willing to try again in the hope we came on an off day. read more

The passion they have in roasting the coffee spills and smells right out the door. I grew up in Europe and had my good share of great coffee, but I think this is the best cup (and beans we use for at home) I ever had. Of course, tastes for coffee are as many as stars in the sky.....for me it feels like something sinful I shouldn't have. But hey, it's just coffee! Ok, the wait is sometimes a minus point, but I just watch them at work and slow down my pace. The sweets they sell are really nice as well. Now open Friday afternoons, hope they will be able to expand the hours. read more

Took my wife 1/2 hour to get a cup of coffee this morning. There were 6 people ahead of her in line, so it took 5 minutes per cup. If you're not in a hurry to go anywhere, the coffee is good, but otherwise go to Starbucks. read more

David Conboy, owner of Karma Coffee Roasters, is ahead of the curve on roasting coffee on site for both wholesale and retail distribution. Speciality coffee roasters that roast on site are more prevalent on the west coast while New England seems to have a Dunkin Donuts around every corner. If you're looking for a great cup of coffee, you are missing out by not stopping by Karma Coffee. Look no further. read more

I needed a place to hang out with a friend on a Saturday morning, and my coworker suggested Karma Coffee Roasters, where her b-friend Ike works. Plans fell through with my friend, but I went there anyway to buy beans for my friend and husband. I was able to get a pound of "half-caff" (50-50%) mix beans easily (they didn't think I was weird). The beans were roasted the day before and were beautiful and oily. I don't even drink coffee (I know, I know!) but the coffee I had from their beans was really good. The decor is nice, more Ikea-esque furnishings, occupied by older luxury-car-driving -self-entitled-middle aged women giving me the hairy eyeball. So I got in, got my coffee beans and got out. The clerk even gave me a free shot of coffee as I checked out. I would love to go back there sometime to just hang out but for goodness sake, they close at 2 PM!!! So that's why I deducted a star. I would love to go there some night to chill out when I have a babysitter, but noooo. Starbucks is open until 9 PM. Bummer. read more

One of the best coffee stores in metrowest. Very affordable whole bean selection. Only critique is that they might improve their seating / put in a bench or something for people waiting for their drinks - it is kind of an awkward zone to mill about in read more

Finally went here and it was worth the hype, fresh roasted coffee that is just awesome. A nice friendly and knowledgeable staff as well. I will be a regular customer to replenish my home. read more

I stopped by Karma Coffee Roasters on the way to an event in Sudbury, and I was very glad I did. The latte I got was very good: smooth, not too acidic, but flavorful. (As an aside, perhaps I am insufficiently cultured or something, but I have never understood Starbucks. Their coffee always tastes burnt to me.) Anyway, I have finally found the anti-Starbucks, and they are tucked away in a very unassuming location in Sudbury on Route 20. Luckily for me they aren't too far from Waltham. If you like Starbucks, by all means, stick with them. They're on every corner, and it will keep the line down at Karma. But, if you aren't sold on Starbucks, try Karma out if you're in the neighborhood. read more

Excellent coffee from start to finish. The cappuccino I had was smooth and delicious. No additions were necessary

Coffee-very good as I had heard from others. Unfortunately the recommenders had also warned me about the owner and his attitude-I had hoped they were wrong. They weren't. The staff that work for the owner are gracious, courteous and helpful. They seem more tuned in to customer service than the owner himself. I guess you have to give him credit for hiring the right people since he isn't capable of it himself. You would think with a name like Karma the owner would be a little more pleasant to interact with. 4 read more

If you can find it behind papa Gino's the coffee is fantastic! Friendly staff and while pastry choices were limited the torte was fantastic. I hope these guys do well. I'm rarely outside of Boston for work as I was when I visited here but if I'm west of Boston I'll go out of my way to return . read more

What a hidden gem!! I gave it 4 out of 5 stars only because I liked -- not loved -- their iced coffee, which had a strong cinnamon undertone. I wish they were open on Sundays, too. Otherwise, though, the staff is friendly, the shop is spotless, and they use eco-friendly plasticware. And I love their elephant logo! read more

Great place with unique character. They roast and grind their coffee in house, seating outside for a small group is definitely a big plus

I have never had a better tasting cup of coffee than that served at Karma coffee. The atmosphere does look like the place just opened a week ago, however it's been around for over 5 years. They serve a full range of beverages including pour over brewing, frothy milk base drinks, and espresso. The staff are courteous and friendly so be prepared to want to leave a tip. read more

Was gifted a cafe mug (small size in beverages) and got a medium hot coffee. It was very good. I have far from a discriminating palate but I find that most cafes offer coffee that tastes burnt or ...that has a prominent cigarette aftertaste (even though they may have other great drinks) but this coffee was very good! read more

Hands down best coffee I've ever tasted. Always freshest beans available. Friendly staff.

Great place! When the person I was visiting with spilled their coffee, the staff was so polite and understanding, and almost immediately provided a free replacement. Nice place to sit and hang out, and the coffee is EXCELLENT. read more

Awesome coffee, awesome people. It's quite literally a HIDDEN jewel, and I will definitely be back.

I like Karma, although I really want to love it. Things that I like: The place is nice, they obviously care about coffee and have a great selection of beans. Things I don't like: The service is sometimes slow (although still friendly), and I really wish they had more roasting variety. Sometimes it seems that all the beans are roasted so dark that they lose some complexity. read more

Some of the best coffee in town. Strong, robust, very nicely roasted. Hours could be a bit longer (I like evening coffee), but this little coffee hideaway hits the mark. read more

A hidden gem! The roasts on their coffees is fantastic -- not like other coffees that taste bitter or burned. I buy the beans and I go for the occasional in-house cappucino. They have amazing machines and the baristas are great. I've never been disappointed! read more

There is just no comparison to their large iced Harrah with a shot of espresso ($3.50). This is where you want to be if you are serious about your coffee. They roast their own beans on premises. Only downfall is basically no food but when you are the best at what you do sometimes it is better not to complicate things. Fair prices too. read more

I like the coffee very much. The beans are always fresh and roasted to perfection. The cafe itself is a pleasant space. The staff are friendly . My one gripe is that this cafe does not own the proper cups to serve their coffee . My espresso con panna was served in a cup too large and heavy for it's contents. The result was a cold coffee sloshing around in the bottom of the cup. I discussed this with one of the employees and she agreed but said most people get it to go or some bring their own cup. What ? Proper Espresso is served in small demitasse-style cups and consumed promptly I would like to suggest that the cafe invest in a set of cups . read more

Excellent, excellent coffee. You can enjoy it there or buy some to bring home. I do both, and am happy to know there a choice beyond the chains of coffee places that permeate the Boston metrowest area. There is little food selection, so don't expect to enjoy a meal with your coffee. However, the small pastry selection they have is good. read more

If you are in the market for roasted coffee beans Karma is the place to go as they are head and shoulders above the rest. Sadly, if you want a bar drink (cappuccino, cafe latte, etc) you may be better off somewhere else. The service is slow and the super young baristas don't seem to know the difference between a latte and a cappuccino. The brewed coffee rivals anything you'll find elsewhere but you'll need to add 10 minutes to your morning commute some days just to get one. Forget about it when the dance school crowd from next door rolls in on the weekends. read more

Wow ! I purchased your Guatemalan at Whole Foods recently because your packaging looked good. I am a coffee fanatic. I usually buy coffee at Starbucks, Peets, and wherever I travel around the I world. Your coffee is superior ! is it the roasting process ? Why can't all coffee taste like Karma ? I paid $17.50 for 1/2 pound in Puerto Rico last week for lousy beans, misrepresented to be premium. I plan to stop by your shop soon and make a Christmas purchase. I never knew you existed until recently. read more

Very disappointed. So many good reviews. So sour a shot. I rode from Hopkinton with the hope of finding a great coffee destination. I ordered a double shot which was provided to me on the house because it was my first visit. Thankfully I didn't have to pay for it. Straight up espresso is the best way to judge a good pull. The coffee was sour and undrinkable. It's possible the barista had an off moment. Or the grind and dose was not correctly compensated for the current conditions within the building. Nonetheless, a shot so poor literally left a bad taste in my mouth should not have been past across the counter. I should have told the owner but chose to leave quietly. Mistake. He should know. Perhaps he'll read this. So, to all you four and five star reviewers who must be consuming lattes and capos, flavored or not, try a shot. If it's sour or bitter, give it back, tell the owner, and vote with your dollars. Sorry Karma, expectations unmet. read more

My family and I have gone here twice already and have enjoyed their iced coffee. It is a cute little coffee shop that is tucked in the back off of Boston Post Road in Sudbury behind Papa Ginos. I had no idea this place was here as they don't really have too big a sign telling you it's there from the road. We found out through dining at the Cottage and they told us they use their coffee. I wish they had longer business hours as they close at 1 or 2 so I don't know how they stay in business with those few hours a day. I don't believe they are open on weekends either,,maybe Saturday? Not sure! They let us walk in the back to watch them grinding the coffee beans and brewing the coffee so that was fun. You can buy freshly packed coffee that tells you when it was made that day, yay! I wish they would give you a discount if you want to have a refill of your iced coffee though as that would be a nice touch but you have to pay same price to get a second one and their large cups are not really that large. It would be a medium sized cup at other locations. All in all it is a quaint little place that is a nice refreshing change from Dunkin Donuts or Starbucks. We will definitely return!! read more
