JavaJug Review – The Best Accessory for the Aeropress

2 Posted by - Coffee, Reviews & Buyers Guides

170720 UPDATE: The Javajug2 is the latest incarnation of the already-great Javajug.

Special shout-out to our NotSoAncient friend Dus who recommended I do this JavaJug Review.  Though I was skeptical at first, the JavaJug has proven to be a must-have accessory for the Aeropress.

JavaJug Review

Watch the video below to see why the JavaJug has become an indispensable part of my daily Aeropress brew.

Show notes and updates:

To prevent bias, I recorded and launched the video without first passing it by the makers of the JavaJug.  After watching it they gave the following valuable feedback to enlighten us all.

  • Regarding the permanence of the logo and fill lines – confirmed they are permanently laser etched and not just painted/printed.
    • From the maker: “Just as a test, I put the logo part of the Jug on the flame of our gas stove and heated it up quite hot. Then I tried to scrape off the logo but nothing happened. It can’t come off.”
  • Why the various fill lines?
    • From the maker: “Another question we sometimes get is “why are there two sets of line marks inside the jug?”  The lines with the numbers are for 8 ounce cups, which is most common in North America. The other set of lines without numbers are gradated for 5 ounce cups, which are sometimes used in Europe and other parts of the world.  You might have noticed that older drip coffeemakers have ‘cup’ markings that seem too small and don’t relate to a regular cup of coffee. After investigating, we discovered they are gradated for 5 ounce cups ( also called demitasse?)  So, to appeal to the global market we also added the 5 ounce lines.”
    • And to add to the global confusion, Japanese coffee manufacturers often measure a “cup” of coffee as only 4 ounces!  As a fellow Asian, I can’t agree …. My morning cup is typically 10 ounces.

the NotSoAncient Bottom Line …

Doesn’t look like much, but WOW!  (That’s what she said)  Could be said of the Aeropress and now the JavaJug too. This combo is unassuming but each so well thought-out and executed, they’ve won the crown of becoming my current daily brew method of choice.


More than reasonably priced, the JavaJug is the perfect gift for all the Aeropressing coffee lovers in your life … Even if that’s you 🙂

Two big thumbs up!

    Your review of the Java Jug convinced me that it would be a good idea to purchase. I didn’t like the idea of spending ~$30 on what basically amounts to a carafe but you’ve made me change my mind. The storage for the Aeropress is a big plus but I especially like the idea of have a dedicated container in which to brew my coffee, especially if I have company.

      Hi Rick, after several more months, I’m still in love with my Javajug. Truly don’t want to make multiple cups via Aeropress without it. Hope you enjoy it as much as I do and thanks for taking the time to write in 🙂

    Nice review. I see reviews on Amazon saying that the latch can rust. Should I be concerned?

    • Dave January 5, 2016 - 10:01 pm

      Thanks Nick! Re: latch rust. I haven’t witnessed it even after daily use over the past several months. Still 2 solid thumbs up from me.

    Just wondering if the JJ can be used on an induction range????Kev

    • Dave March 20, 2016 - 8:02 pm

      Sadly I don’t think so as it is Stainless Steel 🙁

  • Louise August 22, 2016 - 11:03 pm

    I like your reviews, very helpful. I have a question, re: javajug and multiple cups. Do you do 2-3 cycles of inverted brew to get the multiple cups in the jug? I usually use 20-24g/serving, so I’m wondering about the efficacy of ~40g in one brew for more concentrated extract to then be diluted. Seems like the way it saves time is ideally one extracted brew. Thanks!

      Hi Louise, Glad you found me here! Sorry for the delay: life has been crazy. Re: multiple cups. I find if I do more than 2 cups (~40g) I don’t get a great extraction and get weak coffee. Hope this makes sense. Happy brewing!

    Thanks Dave!
    I cam across your site last evening chasing a link to your great sous-vide cooler hack, but then took a left turn in search of a JavaJug – which I had never heard about previously, despite a daily addiction to fussy aeropress coffee.
    I’ve tracked it down and learned that the reason it is hard to buy one at the moment is that they are coming out with a JavaJug2 with a new improved design including a latch with two settings, laser welding, internal volume measurements and a lid! This is all great news for those of us who pack an Aeropress when travelling.
    Thanks for the video review that sent me down the rabbit hole. Righteous work!

      So glad you’ve stumbled upon my ramblings 🙂 And thanks for letting me know about the JJ2! I’m still using the original pretty much every day and love it. GIts utility goes far beyond Aeropress use in our house: it fits our stainless steel Kalita Wave ( ) perfectly, and use it all the time to fill our thirsty espresso machine (I love how fast I can pour without spills or drips). Can’t imagine how it could be better, but good to hear the company is innovating and pushing forward! Cheers and happy brewing!
