Works great. I Can't believe how quick and clean it filters. No sludge.

Purchased as a Christmas gift for my son who loves cold brew coffee. Customer service was very responsive was able to answer all of my questions about shipping and ensured it would arrive in time for holiday. 5 Stars.

As the title says, I love my mason jars. Have been making cold brew in mason jars for years and have been filtering manually. I wish this had came out years ago I would have saved a lot of time...definitely recommned.

The Jarva cold brew system has solved my ongoing challenge of maintaining a consistent cold brew coffee supply at home. After letting the grounds steep for a day, I can easily transfer the cold brew into another mason jar using the Jarva's efficient filtration system. The process is remarkably clean and straightforward - no mess or complicated cleanup required. The system uses standard mason jars, making it both practical and easy to maintain, while the efficient filtration mechanism keeps grounds out of the final product.

Have had the system for a little over a month. Love it. Have made cold brew 4 times. Each time quick and easy. Easy clean up, so glad I was in the first group that did the kickstarter program. This was worth the wait!!!

Love my JARVA. This has made my cold brew process so much quicker and more efficient.

As a lifetime Toddy user, I can confidently say that while both systems make great quality coffee, JARVA makes some clear improvements. The ease of use, quick filtration time, and the use of standard mason jars make it an upgrade to the systems I’ve used before.

Cold brew has always been easier on my stomach compared to hot coffee, and JARVA makes it simple to have a smooth, low-acid concentrate ready to enjoy whenever I need it.

With that said.. it’s not without its complaints. The straw requires a quick one-time adjustment to fit well onto the pump tip. It takes about 30 seconds to set up, and once done, everything fits perfectly and works seamlessly.

The instructions call for using 180 grams of coffee and 1500 ml of water, steeped for 12-24 hours. Personally, I pick up an 8 ounce bag of ground coffee from the store or use a pound of coarse coffee to make two full batches. I don’t think I’ve come across another product that can effectively filter medium grind coffee like JARVA, which is a huge plus.

Clean-up is easy too I detach the filters and rinse them under running water, then toss the used paper filter into my compost bin. No mess if you rinse the jars properly.

JARVA’s thoughtful design that uses Mason jars I think give this product a huge advantage and opens up the market. Also simplifies storage and replacement if needed. I will probably be using my JARVA every week for the rest of my life. It’s a well-thought-out system that improves my cold brew game.

Product has been wonderful to use so far. The potency and volume of concentrate produced has been one of the things I'm most pleased with. Compared to other systems I've used in the past this is the clear winner for me!

Jarva stands out as a true innovation in its field, delivering a product that has redefined how I consume and enjoy coffee! It is backed by an exceptional management team with thoughtful leadership, it is clear that growth and customer success are top priorities. They've created not only a superior product but also a fantastic customer experience.

Of all the cold brew systems I have , JARVA takes up the least amount of space and makes the best tasting coffee. With 2 Ball jars (64oz) I can keep cold brew available anytime very easily.

Love this system. So easy to use and clean. The filters are amazing. Leaves you with a clean cold brew concentrate. Was happy to back this on kickstarter. Took a while to get but worth the wait.

The best part is the ease of cleaning Jarva. All my previous cold brew systems were messy or a huge hassle to clean. Jarva comes apart to easily rinse and wash all the parts. Since it's so easy to clean, I actually enjoy making cold brew again.
I've made about 6-10 batches so far and have had zero issues with performance. I do a 200g hot bloom (187g grounds) followed by a 1300g cold water top up and let sit in the fridge for 2 nights, shaking the mixture once or twice daily. I end up with over 1200g concentrate which I dilute 1:1. Feels stronger than most cold brews I've tried, but that could just be my imagination.
As a former professional brewer, I really appreciate all the attention to details that really matter. It's a joy to use and produces a great product.
Also, the packaging is great. Everything is stored neatly and protected when not in use.
100% recommend to any cold brew coffee lover.
