Quantum is a fantastic brewery now that it's under new management. The owner is around most nights and he seems excited about expanding the selection. Each beer that I tried was consistently very high quality, so I'm looking forward to seeing more experimentation. 4 stars for the overall quality, friendly staff, and better than average seating. An extra star for how quickly this place is improving. read more

This is a badass ass location plenty of food and damn good brew... Give them a try you will not regret it

One star for the nice man working the bar. Got a groupon for my husbands birthday so thought we would go grab some tasters. Ew ew ew. These beers are all so gross I couldn't drink them at all. Like other reviewers stated they were out of many beers. Okay fine, at least the beers they have should be decent. Not the case. They all had a burnt, smoky taste and I literally could not drink them because they tasted so gross to me. They need to master the art of beer making before opening a brewery. I hate to be harsh and ruin dreams, but some work needs to be done here. read more

I agree with a lot of these reviews. Just another average brewery with average beers.

So I went here for the first time today because of a Groupon deal. I would say it is definitely a place I would be going back soon. The beer was alright I just would have wished they had more selection. But other than that the customer service was great. The bartender was extremely sweet and kept on bringing us water and pretzels. Another part is that they offer some games to play while there which makes it more fun. This would be a place I would definitely go again too read more

Quantum Brewing - Flights of beers - Breweries Near Me - San Diego, California

The service was friendly but the beer was truly awful. We got a taster flight and the only way we finished them was because there were 4 of us. The beers taste soapy and like something went seriously wrong. I hope they can turn it around since it's located in a convenient spot. read more

Delicious beer and an awesome owner! Martin was super cool to meet as well! Hadron Collier was super good!

Many great beers to sample; not just IPA. Clean open interior. Dogs welcome. Food options nearby. Plenty of parking.

Good atmosphere, great customer service, neat business concept. We were able to get dinner from down the street and bring it in with us while we sampled. We were also entertained by another customers artistic ability on the gigantic chalkboard and my interest in perplexus (table game). Beers were ok, but not awesome. read more

First off the staff was awesome and had great customer service. But....A brewery is about the beer. Had 3 different beers. The IPA was the only one drinkable. The other two tasted like something went wrong while brewing. One had a cough syrup taste and the other tasted like an ash tray like others have noted. With so many breweries in SD, you can't make painfully obvious bad beer and survive. read more

I left a message on the voicemail of the number that's provided, as well as writing a message on FB. That was 5 days ago and I still haven't gotten a response. How in the world are you a business and not have the professionalism to return a message from a patron? Horrible customer service! read more

Check this place out. You would think that being in a strip mall wouldn't be a good location, but in this case, it works out well. You can pick up your food or order it to be delivered to the brewery where you can enjoy it while trying one of the 12 tasty beers on tap. The food choices include Italian, Mexican, Chinese, burgers, Subway. Parking is easy. The lunch special was $4 pints. The Fissile Material didn't disappoint. Throw in a friendly, well informed brewmaster/owner and it's definitely worth the trip. read more

I work near this place and finally decided to stop by and was definitely impressed. Great tasting beer and a very friendly bartender. I didnt catch her name but she opened my eyes to Annys Burgers who will deliver here. A nice relaxing enviorment with a screen to catch the football games. They are under new management from what they told me and theyre trying to recreate their image. If you have had a bad experience more than 6 weeks ago, you should come back and give it another shot. I will definitely be back! read more

Emily the bartender was amazing. She was super friendly and answered all of our questions. Even recommended another local brewery. Beer was great too! We did the pick 4 sampler. Most were complex and unique. read more

As with my tip. There's a smokey, cigarette ash taste with every sip of their beers. Quantum needs to either check the piping or the water quality. It was my first time there and it could be my last. I hate leaving such a review but their issue cannot be ignored. I love local Brewers and hope for the best to quantum! read more

I love coming to this place whenever I can, I always receive wonderful service from the friendly staff. Support your local breweries!

LOVE the Solar Flare ! I like fruit flavors in the beer so this was perfect !! Didn't try any others because I liked this one so what was the point ??? Will be back though to try the ginger one Bought a growler to get me through the.days they aren't open ! The 4 stars is based on the inability to get there on days off.work !! I live close and really like the beer. Another plus is the proximity to good food - Filipis pizza is right across the street and you can have them deliver !! Great combination of food and beer ! read more

Seriously gross beer. Not just because I don't like any of the styles - I love em' all. They have a smoky, dirt, almost infected flavor that hits all of their beers. They need to get some help. read more

I work just a couple doors down and have been coming here for years. The beer and the service is top notch! Quantum also has one of the cleanest bathrooms I've seen at a local brewery. Definitely recommend! read more

Brewery and owner.. amazing. First of all, any normal person should check out a place and judge it for yourself! Their bourbon aged beer is super good. Highly recommend! Also nice it is not on busy convoy steet where you can't find parking. read more

First time here was a great experience. Really good selection would definitely recommend for anyone looking for some new beer to try

Under new management and this place is great! Super friendly honest owner who knows his stuff. The habanero beer is so complex and worth the visit in its own right. A real scientist with real brewery talent. Don't let the old reviews turn you away, sit at the bar and try a flight or 2 of all the options. I hope to see the blood orange barrel aged soon! read more

Emily was very helpful and the beer was great, and the people were very friendly. Had an awesome time, we will be back soon.

The best wheat beer in San Diego, hands down. You can go to Stone and Ballast Point for IPA's but if you want flavorful beer outside of India then land at Quantum. Wasn't expecting anything out of the ordinary, we were in the neighborhood for a late evening event, and my buddy and I saw Quantum and said, let's go crash there until our event kicks off. When you walk in, expect the most wonderful bouquet of wort to excite your nostrils because they brew in the same room that you're drinking your pint. Dad always said beer is best closest to the brewery and you can't get any closer than this. The wheat beer just knocked us out because we'd never had anything like it in San Diego. The amazing flavor and mouthfeel were indescribable. I wanted to know the secret and walked past the curtains and found the brewer and a big pot of wort in the transition to beer. Great conversation and fantastic beer. Gave them 4 stars for now because they didn't have growlers (maybe they do now) so we weren't able to take any with us, and until they become a behemoth brewer, and open up a fantastic brew pub, I'll award them 5 stars. This is a simple place, not far from Society, many restaurants in the same shopping center to bring food in as you taste so drop in and be ready for great beer and good times. Cheers! read more

Good beer selection and super close to home. I like the physics-oriented theme and all of the clever beer names. The chalkboard wall is pretty sweet, too. read more

An amazing brewery. As a fan of math and science the atmosphere appeals to those individuals who can freely express their formulas and theories on a chalkboard. The beer is great and is name after scientific principles(I.e. antimatter, hadron wheat, etc.) The staff is awesome and very talkative. Very great atmosphere. read more

After living in North Park and being spoiled by the number of quality breweries we could walk to, my husband and I were excited to find a nearby brewery after moving to the burbs. We were not disappointed after trying Quantum for the first time this weekend. I am an IPA lover and their session IPA was delicious - a little earthy, very flavorful, and really fresh. My husband likes wheat and his comment was "I think that was the best wheat beer I've ever had." Plus, the atmosphere is very relaxed, great service with really friendly staff, and kid and dog friendly. We will be back! read more

I love the whole science theme and name of the beers. I just wish the beers were as good as the names. I got a flight of beers and barely finished them all. I ended up rushing over to Societe just so I could have a respectable beer in my mouth. The Uncertainty Red I had was skunky. At least it tasted that way. Not sure if it was old or what. Judging from other reviews, I am not the only one who feels something was bad/off about the beer taste. The Chain Reaction Session IPA was probably the best beer I had. I went this past Saturday and had a very friendly bartender helping me out (hence the why it is 2 stars and not just 1 star review). I would recommend Quantum if Societe and Helm's Brewing are packed. They are nearby and I'd much rather go there or recommend them to other beer drinkers. I do hope Quantum can fix whatever is ailing their beers and should probably sign up for some better marketing/advertising soon. read more

Fantastic little brewery! The owner, Martin, is knowledgeable and friendly. Some of the best small batch brewing I've had. I would highly recommend making this a stop if your in the area. read more

Great tasting beers. Good atmosphere. Tuesday night trivia is always great here. And plus, the neighboring pho and taco places will deliver!

In a world of yelp douchebagery, this place transcends. A true nano experience. Nicely balanced selection, and a humble local ambiance. This place is proud of doing its own thing. read more

Wanted to see if the reviews were true. Beer is pretty bad. Extreme Fusel flavor in their ipa. Obviously, poor temp control

Decent spot.....they don't have any food there which is normal for most breweries but they have a couple of restaurants that deliver which is very cool. read more

Great place- long overdue review here. I have been a patron of this establishment for the last two years (even before new owner) and it only gets better and better. There offerings have matured and the business has a varied offering of malted waters to satisfy many different tastes read more

Good service. Just terrible beer. Bought two flights to be able to try all of them. 4 are flavored. 4 are regular beers. The regular beers are not as terrible but still very very bad. The boron was only slightly below average. I hate feeling like I'm bashing this place. They just need to make better selections. Your palette may be different so it's cheap enough you can give it a try. Just don't expect to love any of them unless you like beer that tastes like jalapeños or or salted Carmel a**hole. read more

A standout! Great beers and ever improving as new owner Martin Beaulieu gets his traction. Currently brewed in small barrel batches, Martin (a French Canadian PhD biochemist who KNOWS good beer and how to make good beers) is striving for perfection. I tried 8 testers (IPAs, wheats, a brown and a stout) and liked the balance, body and flavor of each one. Three nice additional points: very conveniently located in Kearny Mesa right off the exit of the 163/Clairemont Mesa Blvd (by Sonic and Filippi's)., lots of free parking, and two eateries as neighbors that deliver (Anny's Burgers and Subway). Quantum is also one of those beer friendly places that will fill anyone's growler if the legal stuff is masked over. This was my 48th San Diego brewery and one of the best (my drinking companion is a beer judge and has visited over 80 local breweries and agreed wholeheartedly). Try it! read more

Great place with a great owner. The Chain Reaction had just what i look for in a session IPA. Then I had the Cyano Cream Ale which is a blueberry cream ale which is now a favorite. Will definitely return. Cheers Quantum Brewery! read more

I have visited Quantum brewery three or four times. Each time was a great experience. I am new to craft beer just moving to San Diego two years ago, but the bar tender was very informative about the beer selection. I explained my taste and she created a flight that was perfect! I was impressed with her knowledge as well as the taste of the beer. SOLAR FLARE IS A MUST!!! All the beers tasted great. It was a chill atmosphere with a unique theme. ITS DOG FRIENDLY & I love that my dog was able to get a drink as well. read more

Great first stop for a brew tour in honor of our daughter's 21st birthday. Really liked all the beers I tried. Staff was very friendly.The atmosphere is fun, but I think will get better with time. They are pretty new. I would recommend Fissile and Chain Reaction. read more

Visited last night and the Solar Flare was so good had to come back for more. It's a wheat beer with a subtle but poignant blood orange flavor. Not too sweet yet not a faint after taste either. They got it just right. The ambience is typical of most microbreweries; spartan. Yet very friendly with games and allowing patrons to bring food from neighboring restaurants. I brought Mexican from the restaurant next store (basic and not fancy). Location is not an upscale strip mall but good enough. I'm visiting from No. Cal. and look forward to Quantum during my next visit to San Diego. It would be better if the bottled and distributed their Solar Flare. read more
