Welcome to Blackwater Coffee Co.

“ We've been dying to try this coffee shop and when the opportunity arose we jumped on it. Beautiful coffee shop, amazing coffee and service! ”

“ Brilliant coffee shop with amazing atmosphere, very friendly staff, amazing coffee, and fresh roasted beans! I came here to get some coffee beans after being recommended their Three Gringos roast, and I'm thoroughly impressed! I loved the vibe inside and would love to come back to sit down and do some work/spend some time here. When the weather's nice, the front windows open up, and the boundary between indoor/outdoor space is blurred; amazing! While I was getting my beans, I decided to try their Vietnamese Iced Coffee, since that is primarily what I've been making at home and mostly intended to make with these beans. Somehow, their version tasted WAY better than I've ever made it at home; I have no idea how. Thanks for being such a positive addition to the area! ”

“ This is the best coffee shop I have ever been to! The coffee is delicious truly one of the best I have ever had, and the desserts and breakfast bagels are amazing. The staff are so sweet and the owners are amazing people. Would definitely recommend going this is my favourite place! ”

“ Backwater Coffee Co. is hands down one of the best coffee spots I’ve ever visited. From the moment you walk in, the vibe is warm, welcoming, and cozy — the kind of place where you instantly feel at home. The staff are friendly, knowledgeable, and clearly passionate about what they do. The coffee? Next level. Every cup is rich, smooth, and brewed to perfection — you can really taste the care that goes into every roast. I tried an iced skinny vanilla oat latte and a date square - they were incredible. Their pastries and snacks are so fresh and delicious — perfect for pairing with a good book or a work session. If you’re in the area (or even if you’re not), Backwater Coffee Co. is worth the trip. It’s more than just a coffee shop — it’s a community hub, a creative space, and a caffeine lover’s dream. Can’t recommend it enough! ”

“ Stopped in and tried both the mocha latte and cappuccino—absolutely fantastic! The mocha latte had just the right balance of chocolate and espresso, rich but not too sweet. The cappuccino was perfectly crafted, with smooth foam and bold flavor that shows they really care about their coffee. The café itself has such a cozy, welcoming vibe, and the staff were super friendly. If you’re visiting Sarnia, this is definitely a must-visit spot! ”

“ Loved my experience and atmosphere here!! I'm from Michigan and was camping in Sombra. With the weather being all over the place, I had to tweak my plans which led me to needing to kill some time! That led me here. The staff member (maybe owner?) was friendly and helpful with his recommendations- I ordered the cardamom latte and leek and parm croissant and it was SO delicious, buttery, savory and flaky. The garage door being opened to the outside is always nice for fresh air and a view. ”

“ Overall rankings - portion 4/5, presentation 4.5/5 and taste 5/5. Such a great find in Sarnia! The staff was super friendly, and the restaurant had such a great vibe with the decor, lively atmosphere and large open door with nice cool air coming in the warm weather. In regards to the food, we got a mocha latte and a dolly bar. The mocha latte was delicious, beautifully crafted and plentiful. The dolly bar was just amazing and we could not get enough. It was so sweet, had a great texture and the different ingredients mixed in so well, especially the chocolate chips. Such a great treat and will be back to get more! ”

“ Blackwater Coffee is absolutely amazing! The owners are incredible and truly go above and beyond for both their customers and the local community. They’re always supporting other local businesses and even created a special branded Dream Home coffee for us this year, which was such a thoughtful touch! Their space is warm, welcoming, and collaborative, I love popping in to chat with the staff and customers. The atmosphere is always so positive and genuine. And of course, I can’t forget to mention how good their coffee is! They take their craft and roasting process seriously, and it shows in every cup. I love this business and everyone involved. Sarnia is lucky to have them! ”
