    Cool place Old style industrial park brewery taproom Loved it, great selection Staff were awesome

    Their sours are amazing!! Every beer we have drank here have been good if not great. They have alternating food trucks in front and they sell pita and hummus inside. Definitely check out this place if you love beer. The service is a hit or miss. They have both indoor and outdoor seating, so dogs are welcomed.

    Happy hour $5 beers all day on Mondays. A variety of beers. We stuck with the hazies and sours. Great deal. Staff is nice. One restroom. You can bring outside food. They also sell some snacks like hummus. You can bring dogs.

    Pretty tasty flight!

    Tucked away in an industrial complex (like so many great small breweries!), they've got tasty beer, friendly staff, and a couple TVs usually showing sports. A nice rotation of food trucks is outside every day.

    Hazy ipa

    Alpha acid was a great find for me and my friends. Tried the hazy ipa called the police something, it was really good. It was $9 for a pint. There's a calendar there with food pop up trucks, Shamsh'd burgers was there the day we went and it was delicious pairing with the beer. Would recommend trying them out too. Service is cool, there was only one person working. Also saw that there is trivia night on Thursday from 7-9pm will have to try that it out and see how it is one of these days. They have two TVs both playing the college football games. Some board games to play here with your friends. Parking here is pretty limited.

    Belly up to Alpha Acid's main counter to view one of many beer choices before ordering.

    I have invited friends to meet me at Alpha Acid Brewing in Belmont over the past several years to enjoy some quality craft brews and Alpha Acid's friendly neighborhood vibe. They've been around for at least a decade brewing and serving some of the best craft beers on the Peninsula. It's a straightforward setup... patrons order at the counter then sit at either an inside table or an outside one to sip and chat. On my most recent visit, Matt was working the taps. He's a friendly sort and very knowledgeable about the beers Alpha Acid offers. Matt can pair your taste in beers with a flavorful ale, lager or amber. I prefer IPAs, so a buddy and I sampled Haze Ventura (7% ABV) and Hop Secret (9% ABV). The Ventura is a West Coast IPA... it's citrusy with a very palatable bitter finish. Hop Secret is a hazy that's less bitter than its West Coast cousin, but it has the hazy IPA signature rich, fruity texture. If you also prefer IPAs, you might just have to just flip a coin. Either way, you win. Alpha Acid features pop-up food vendors, and it's a good bet either a premium pizza or authentic Mexican cuisine will be available. My buddy ordered a burrito. There's nothing better than tipping a horn while enjoying a delicious made to order burrito. If you like beer, check out Alpha Acid. They're open in the afternoon until early evening. Prices are good. Drink responsibly... every time.

    This place is so cool! The bartender was VERY welcoming. I can see people buying more beers just because he's so nice. I got an awesome flight. "Slices" was the most refreshing since it's so hot outside. All the beers are amazing. It was hard to choose a favorite. If you ever find yourself in Belmont, Ca this is one of the best places to check out. Family friendly. Safe area. Cheers!

    Stopped by on a Friday night. Alpha Acid is nestled into the back corner of a commercial center with lots of offices and businesses. They have different food trucks onsite daily and a decently spacious interior with plenty of seating and a few outdoor chairs as well. We got a flight of 4 different beers and everything was great. Service was incredibly welcoming and friendly as well. Because of its location, parking is easy. They have a few retro arcade games and some board games to play inside as well. Prices are very reasonable. Looking forward to coming back!

    Brilliantly brewed beer from a great group of guys and gals. The space is terrific for all ages, and the food trucks are always phenomenal. Trivia nights are on Thursdays at 7pm. It's a hoot, man.

    The beer menu!

    A superb local craft brewery in Belmont, California. I highly recommend to come and visit this amazing brewery that's celebrating its 12th anniversary!

    Trivia Thursday's is how we first heard about this place from a friend. The beer is delicious and they always have a new great food truck parked outside. Bo does a great job hosting!

    Mango seltzer with real mango in it!

    My husband and I have been on a mission to try out more breweries between where we live and work, and Alpha Acid was on our list. Needless to say, it exceeded our expectations and then some. We are big brewery goers and always look for a few things while checking out breweries: 1) a solid lineup of beers and ciders or seltzers 2) rotating schedule of food trucks 3) friendly staff 4) the ability to taste before choosing, and 5) a fun environment with games and a good crowd. Alpha Acid has all this and more! There are pinball machines (sadly didn't have enough in quarters but next time), one of the best taco trucks we've had (El Amanecer), great staff and many beers to choose from. Don't sleep on their seltzers--I had the best seltzer I've ever had here, made with real Alphonse mangoes (the Cadillac of mangoes, IYKYK). Pick up some crowlers to take home at the end of your visit, you can mix and match!

Server did not really seem to want me to order at the bar instead of through the QR app. I ordered two flights and two single drinks for our party of four and one of the flights was not correct when brought to our table. Regardless we drank through the flights, enjoying the nice weather that day. Went up and purchased a mix and match four-pack on the way out, tipped well despite the so so service. Made our next stops and when we got home later was really disappointed to see the beers I brought home were not the ones I asked for. I know, my bad for not checking before I left, but I was left with the feeling that there was no attention to detail regarding the service we received that day. Two stars because we enjoyed most of the beers we did try.

Right when you walk in, the vibe feels welcoming and easygoing--perfect for groups or even a casual solo stop. The space has a great indoor/outdoor setup, so you can choose between a lively indoor atmosphere or a more relaxed patio feel depending on your mood. There are also a few TVs around, making it a solid spot to catch a game while hanging out. What really stood out was their impressive selection--30+ beers and seltzers on tap, with a little bit of everything for all tastes. Whether you're into hazy IPAs, crisp lagers, or something lighter like a seltzer, there's plenty to explore. The staff was super friendly and knowledgeable, taking the time to walk us through options and offer recommendations without any pressure. You can tell they genuinely enjoy what they do. On top of that, they also stock a nice variety of bottles and cans in the fridge, which is great if you want to try something different or grab something to-go. It adds a bit of a curated bottle shop feel to the experience. They also serve some light bites like empanadas and pizza, which paired well with the drinks and made it easy to settle in for a while without needing to leave for food. It's not a full restaurant, but definitely enough to keep everyone satisfied. Overall, this is a great spot to kick back, celebrate with friends, or just explore new craft beers.
