Casper Fermentables - Bagels, Kombucha, Sourdough

We love this place. Their lox bagel is the best bagel sandwich in town and we all love their rugelach. We make excuses to have a reason to go there.

I love this place. Today I pre-ordered a couple kimchi tuna melts to be ready at the random time of 11:15. When I walked in, at 11:15, they were just boxing them up. I also grabbed a couple sesame tahini cookies. If either of these items sound like they would not be delicious, you could not be more wrong. Everything is great, but that sandwich really slaps.
And if you need a cinnamon roll the size of your head, this is the place to be.

Overrated and overpriced. I lived in NYC for nearly 5 years. I know a good bagel. Ate them all the time.

The bagels here are small, dense, and rubbery. In other words, the opposite of what a bagel should be. Could barely enjoy my lox bagel without damn near all the toppings falling off because it was so rubbery that I had to wrestle the bagel to get a bite. It required actual effort to eat and was needlessly messy as a result.

The layout of the place is really bad. The space can barely handle a 4 person line with how it’s currently set up, and there was at least 4 people in line the entire time I was there. There’s definitely a smarter way to utilize the space.

I will give them credit on a couple of things: 1. The toppings - the lox, whitefish, cream cheese, etc., all seemed good. 2. The service was good.

I was expecting more from this place based on the reviews. Overall fine, but don’t expect to be wowed or feel like you got your money’s worth.

I popped in here on a whim to get a sandwich and I was blown away. The food is amazing. They make their own bread and pastries and they are incredible. This is now one of my go to sandwich places if I'm looking for lunch.

🤤🤤spicy turkey 🥰

Everything they serve is amazing…fresh and of high quality. We always keep the bagels on hand for out of town company. So happy to have them within 15 minutes of our home!

We got the spicy turkey sandwiches and honestly, they’re some of the best turkey sandwiches I’ve ever had—absolutely packed with flavor and perfectly balanced heat. But wow… the wait is something else. If you’re hoping to grab a quick bite, this might not be the place. It almost feels like you’ve been forgotten while waiting. The food is worth it, but just know what you’re signing up for: incredible sandwiches, delivered eventually.

No one in Austin is doing bagels like Casper Fermentables, they are unmatched! This place has quickly become our go-to weekend breakfast spot. Our favorites are the lox bagel, the pizza bagel (try it with the jalapeño bagel- yum!), and the incredibly delicious sourdough cinnamon roll. Casper Fermentables is also perfectly located next to an awesome coffee shop (Stouthaus) and has plenty of outdoor seating. Every weekend we’ve gone the place gets more and more busy, this place is a gem and people are catching on!

Delicious lox bagel. The salmon was great, the everything bagel tasty and crunchy, and the tomatoes, onions and capers just right. The other sandwiches and bread look fantastic so I’ll be back to try them.

Another visit: I tried the veggie sandwich and the veggie part was excellent; tasty roasted peppers, fresh avocado, and greens. Also, the chips were the crispest I’ve ever had. But the focaccia bread was a letdown, extremely bland and devoid of taste. Still a great place for a bagel or sandwich.
