If you're looking for a coffee experience that brings a wide range of flavors and truly breaks the mold, you have to try River Phin Coffee. I first discovered them at the San Francisco Coffee Festival, and it's been my go-to ever since. The founder, Vy, is an incredible force in the industry--she's a Certified Coffee Quality Grader, one of only 400 in the U.S.! What makes her coffee so unique are the innovative fermentation methods. We're talking next-level stuff, like placing bananas right in the fermentation vat to develop flavors you won't find anywhere else. Here are my top three favorites on my regular order: 1. Diego Bermudez Pistachio Cake: Features pistachio cream, followed by warming notes of cinnamon and cardamom. 2. 96B Project Liberica - Quảng Trị, Vietnam: A rare find that brings the unique flavors of Vietnam to your morning pour-over. 3. Pink Borbon Banana Milk Cake: This is where that innovative banana fermentation really shines. Vy offers a wide range of exotic beans from Vietnam, Thailand, Colombia, and beyond. Support a master of her craft and upgrade your home brewing! read more

There's a pop-up coffee stand at the Foster City Farmer's Market, open every Saturday. It has been a regular fixture for some time now. They offer a variety of drinks including regular espresso, latte, cortado, as well as unique options like black sesame latte and Vietnamese coffee. They also have limited-time coffee specials and sell coffee beans, which seem quite popular. The owner is very friendly. I tried the Vietnamese iced coffee, which came with the owner's recommendation to add pandan and coconut milk. It was bold and delicious, though I wished the serving size was larger - just a few sips and it was gone. Despite the smaller size, the prices are reasonable. I look forward to trying other drinks in the future. read more

I was going to bring the gift of coffee to a friend and River Phin helped me find just what I needed! If you have any questions, Jana is very responsive over Instagram and explaining what she has. As a small business, River Phin finds it's greatest strength not only in making a great product, but also being able to connect directly with customers at the farmers market and online. They sell whole beans on their website and in-person, but if you need them ground like my friend they can accommodate. Jana offered to grind the night before, paid via Venmo, and I picked it up the next morning! At the farmers market, I also got the Old Fashioned Vietnamese coffee - rich in flavor and great to sip on. Right at 9am, there is a line to order. Looks like one of the hottest tents at the market! I'm glad I was able to catch them before leaving town. read more

They have amazing coffee and beans here! The owner is very kind and tries to remember her customer's names. She also seems very knowledgeable about coffee and the various preparation processes. If you are looking for coffee that is natural, washed, or fermented, then I would recommend this place. I would also recommend the Pistachio Cake and Pink Borbon Banana Milk Cake beans if you prefer pour overs! read more

Love that it's a family business! They are occasionally at the farmers market in foster city on Saturdays, please try it if you have a chance. I love coffee in general and being Vietnamese I can be a bit particular with how I like my Vietnamese coffee. I got the pandan iced coffee and it was perfect, not too sweet with the right consistency and actual pandan leaves inside. Service was a little slow, but they were busy. read more

Their coffee is really good and one of the most complex Vietnamese coffees I've tried. The owner is a certified coffee quality grader and knows her coffee really well.

Best coffee at the Foster City Farmer's Market! I got the traditional Vietnamese Iced Coffee and it was strong as expected! Wait wasn't too long to order and even to get my coffee as well. My wife got the Pandan Latte and really liked it; you can really taste the pandan essence. They also sell coffee for brewing at home, if that's what you're interested in. If you're around on a Saturday, I definitely recommend. I plan to come back for sure! read more

River Phin Coffee is, without a doubt, my absolute go-to place for beans. Visiting their stand at the Foster City Farmers Market has become the highlight of my week every Saturday. If you are serious about coffee, you need to meet Jana. She is an award-winning Roast Master with an incredible philosophy on sourcing and roasting. Her selection of Asian specialty and rare coffees is unlike anything else you'll find in the area. Honestly, being a regular here has spoiled me, completely raised the bar. I've become much more particular about my coffee because Jana's roasts are just that clean and distinct. My current favorites are the Geisha Village, Lychee Bloom, Son Pacamara, and Magnum Sidra. I really hope more people discover River Phin and understand the care Jana puts into her craft. You genuinely just have to taste it to understand the difference. Highly recommended! read more

I first tried River Phin Coffee Roasters at the San Francisco Coffee Festival in 2024. Their cà phê sữa đá (Vietnamese iced coffee) was the best I had at the entire event! The coffee was rich and dark with a fragrant aroma. The sweetness of the condensed milk brought it all together. Smooth, bold, and the right balance. Since then I have followed Vy, who runs this small business with help from her mom. They set up at the Foster City Farmers Market every Saturday. It has become my weekend routine to grab my Vietnamese iced coffee there. Most of the time it is Vy's mom in charge of the iced coffee drinks. That family touch makes it even better honestly! The line can take a little time but every cup is worth it because it is always made fresh to order. I also pick up beans from their booth. My favorites are the Saigon Dark Whiskey and the Countryside Robusta. Both are strong and smooth with that deep flavor I look for when I brew at home. The beans are fresh and roasted with real care, and you can taste the difference right away. River Phin is the kind of local business I want to support. It is small, personal, and focused on quality. You can feel the passion Vy and her family put into every bag of beans and every drink. Easily some of the best coffee in the Bay Area. Highly recommend checking them out when you're around the area! read more

I've been a regular at their Foster City farmers market pop-up for quite a while now, and I can't recommend them enough! My go-to drinks are the lavender latte, bee pollen latte, and the pandan cloud Vietnamese coffee.(Keep an eye out for occasional specialty espresso too) I have bought a few coffee bags from them and they were equally exceptional. The "Pink Borbon Banana Milk Cake" has been one of my favorite coffees this year. read more

I love my Peet's Major Dickason coffee every morning. After trying River Phin's coffee at the Foster City farmer's market, I've switched to their specialty roast of Jakarta volcanic beans. It's dark and smokey with more of a nutty profile than what I get from Peet's beans. So good in fact, I ordered a big ass bag. Looks like a family run local business so that makes it even better. read more

Vy's coffee stand is such a treat. She roasts her own beans, which she sources herself, and the quality is outstanding. If you're at the farmers market, make sure to stop by--you'll get incredible coffee and support a truly talented local roaster. read more

My favorite is the decaf coffee from River Phin, it is by far the best decaf beans I've had. I used to get Blue Bottle night light decaf and Counter Culture, but those don't hold a candle to the Mai Decaf. I also love the speciality coffee that they have at the farmer's market. One of the regular espresso has lychee notes in it. The beans are Asian ( Indonesia, Vietnam), so I find the profile really unique and not like your typical Colombian bean at most cafes. If you see the Son Pacamara roast, I highly recommend it. It's one of the best coffees I've ever had. Creamy, caramel, I can hardly believe this is the natural taste of the bean! Whether I'm making espresso at home or getting a latte at the farmer's market, the coffee really does set the tone for the rest of my day. Can't do without it. River Phin is my goto coffee -- highly recommend! read more

If you're a serious coffee enthusiast or a home barista, you have to stop by River Phin's stand at the farmers market. The owner, Vy/Jana, is incredibly passionate about their craft and is always happy to chat about the latest beans, brewing methods, and what makes each coffee special. I've had some of my best coffee experiences from their beans. The quality and value are exceptional; they consistently offer a selection of rare, high-end beans like Gesha and Pink Bourbon, but also have a great variety of more standard and affordable options. Their attention to detail really shines in the cup--the Lychee- and Banana-cofermented varieties I've tried were so delicious and unique, and I love that they consistently highlight incredible coffees from Asia. I always look forward to seeing what new beans they have in rotation. And it's not just about the beans--their prepared drinks are fantastic, too. I always grab their Pandan Vietnamese Iced Coffee for a sweet treat while I'm doing my shopping. Whether you're looking for a great cup of coffee on the go or a fresh bag of beans to dial in at home, I highly recommend them. read more

I also buy her coffee beans to make at home. read more

We always look for this coffee at the farmers market. Some magic makes it taste so much better than most coffee.

She was kind and helpful, French roast was excellent, free sample made a nice day even better

This is hands down the best coffee I've had in the Bay! If I could give a 1000 stars, I would. It's incredibly smooth, rich and flavorful, I look forward to it every time I walk by. I'm forever a customer, once you try it, nothing else compares. read more

If you're deep into coffee, this is the place to get some really unique beans/pours. They locally roast, and the owner is in the booth to answer any questions you have. She's a q grader, which is equivalent to a wine sommelier (if you've ever seen that netflix special you'll know how hard it is to get this designation). Out of curiosity I googled it and there are only 108 q graders in the USA and only 2000 q graders in the world. Anyhow, that should tell you how serious they are about coffee. The beans are always nuanced and tasty. I recently had a lychee espresso bean latte that was super tasty and unique. This isn't starbucks where they pump a bunch of sugar into the drink to make it taste like lychee, the beans have the flavor naturally and you get hints of it in the nose and on your palate. They also make vietnamese iced coffee drinks and seem to rotate the specials and flavors here. Again, it's an elevated experience, not what you're getting from a pho restaurant. I guess that's the overall vibe here, everything you like about coffee, but at a higher quality/sophistication level. If you're into coffee, this place is worth the stop, highly recommend, two thumbs up, five stars, etc etc. read more
