We've looked long and hard for a scale that we can recommend for our avid manual brewing friends. The scale needed to have a high weight capacity, fast response time and precision calculations, and the ability to disable the auto-off feature to ensure the scale would not shut off mid-brew. The Jennings CJ4000 is the first scale we have offered that meets all of these requirements. With a 4000 gram capacity, accuracy to .5 gram, and the ability to disable the auto-off feature, the Jennings scale is the perfect companion to manual brewing.

Features:

  • Reads in Grams, Ounces and Pounds
  • Weight displayed in .5 gram increments
  • 4000g Maximum Weight Capacity
  • Auto-Off feature can be disabled to allow for uninterrupted brewing.
  • Tare and Zero Function
  • Tactile Rubber Keypad
  • Cover that doubles as a Bowl with Pour-Spout
  • Large LCD Display
  • Round, Stainless-Steel Platform
  • Runs on Batteries or Included AC Adaptor
  • 3 AAA batteries included
  • Advanced Parts-Counting Feature
  • 20 Year Warranty

Not fancy, but it gets the job done

Full Disclosure: I work for Prima Coffee. The Jennings is my scale of choice for my morning brew routine at home. This is a great scale for the money if you are wanting something simple and cheap for pour over brews. The scale has a large weighing area which accommodates most any brewer or server that you want to stick on it and it has a large enough weighing capacity to measure the full weight of the server, brewer, grinds, and water. Simple to use yet not overly simplistic, there are a couple of nice touches thrown in. The backlight LCD I have found to be really useful, providing enough contrast to easily keep track of the current weight and not susceptible to shadows washing out the display. Being able to disable the auto-off feature means that I no longer lose track of a long brew midway through the process. While it is great for pour over brewing, don't expect to be able to use it for espresso. It only increments in .5 gram increments which means it is is not precise enough for pulling shots. It also is not going to win any awards in the looks department. Bottom line, if you need a basic scale that works for pour over brewing and you don't want or need a lot of premium options or just want to save your pennies to invest in other parts of your brewing process, then the Jennings is a great choice.

Great little scale, love the tare feature and the way the cover protects sc

Bought this a couple of weeks ago to go with my areopress coffee maker that I got from Prima also, couldn't believe that 1 gram difference can make such a difference in taste, this helps to make a consistent great cup of coffee. Thanks Prima

Very versatile

Easy to weigh your coffee and then weigh the "volume" of hot water you are adding so you know your exact proportions without cooling off the water. A Good mail scale too, I think.

Works perfectly!

Couldn't ask for a better tool to make coffee with. It's accurate and easy to store. Not really much else to say, other than this is a great buy.

Exactly what we needed!

I bought this for my husband's birthday and he was so excited to start using it! We're new to fancy coffee products like this, but it was simple to figure out. Can't wait to purchase our next product from Prima!

Nice scale. Does everything as described. Would purchase again!!

Nice scale. Does everything as described. Using to weigh coffee for pour overs and grinding. A timer integrated into the scale would be a nice upgrade to what is already a good unit.

Great scale. Everything a home cook will need

Bought this a couple weeks back to start baking more (and more accurately). Has been fantastic to use. Easy, quick, accurate, nice small size, very functional.

You NEED this scale!!!

Let's face it, the ability to achieve the proper ratio of coffee-to-water is essential to brewing great coffee. I would place a gram scale right up next to a good grinder as the two essential pieces of gear needed to achieve coffee nirvana. My coffee tastes SOOOO much better now that I've started weighing for ratio. The difference is like night and day. It simplifies and brings consistency to the process of home brewing and helps to conserve my precious beans to boot. The fine folks at Prima asked me to do a review, which I NEVER do. I had a tiny issue with my order and they took care of me instantly, no questions asked. Impressive service and I will be a repeat customer! Awesome shop, Awesome scale!!!

Accurate and easy to use

First and foremost accuracy is of most importance when it comes to buying a scale, and this scale has it. It's accurate, has a clean aesthetic, and is large enough to fit a chemex 6 cup pour over brewer on. The only minor drawback I would say is the loud beep that happens when you press any of the buttons. However If you are working in a loud shop it isnt even that noticeable. Great scale!

Great scale!

I bought this because I needed a food scale. The ones I looked at were only battery powered with no option of ac and did not weigh in .5 gram increments. I've only had it for a week but it is very easy to use. Even my parents are able to use it.

Integrates whole brewing process

Been using it two three times a day and finding that the scale works easily and without glitches. It turns on easily and sets back to zero before each of three measurements I make during brewing. My process is as follows: 1. Weigh 420g water directly into kettle and the heat to 190 degrees Fahrenheit. 2. Weigh 28.5g coffee beans into Scale lid pour into grinder and grind at setting between fine and medium and pour into cone with filter. 3. Weigh about 400g hot water while pouring over ground coffee in cone above 14 oz. drinking cup, pausing at about 80g for blooming. 4. Drink coffee.

MADE FOR COFFEE!!

From the moment I opened the box I knew this scale would be awesome! Immediately when I set my grinder on the scale to measure beans I noticed how off my old Taylor made kitchen scale was when the CJ4000 began to give me a more accurate precise reading of my grinder and beans. The scale is a great size (big enough to hold any of my brewer, but small enough to not crowd space. I use a pour over stand and this scale fits perfectly underneath with out me being nervous about the stability! The backlight helps a lot for brewing in my dark room without having to turn on every light in the house in the early morning hours. The cover is the perfect bowl to pour beans into (Although the pour spout isn't really bean friendly the corner of the cover work perfectly as a spout). I have noticed that if you set something on the edge of the scale it could give you a reading .5g different than if you were to set it directly in the middle (it hasn't been a problem though, I typically brew in the middle of my scale). The last thing I would like to mention about the scale is the response time(It blew me away!) I use to think that the reason my old scale took a second to give the weight was because of the "water in the air" during my pour. I have now found that to be false when this scale gave me the exact reading almost immediately as I stopped pouring. Buy this scale. Would also like to shine a light on this wonderful company that shipped the scale in Fast time, and went above and beyond by throwing a little extra goody in the package for me (while I don't expect this with all of my future purchases it was a delightful surprise and I will for sure buy from here again) Two Thumbs Up!

Very quick!

I noticed my old scale was kinda slow but I adjusted to it in my pour but I never realized how much of a difference that a scale with quick weight reading would make such a big difference in the way I pour. This scale is not much more money than you would probable spend on any other scale for coffee and it is definitely worth all the buzz I hear about it. And for those of you like me who don't keep batteries on hand, it has an wall plug adapter that you can switch to.

Great scale at a great price!

I bought this scale kind of on a whim for my new Chemex. I was going to spend a bit more time researching different scales, but when I read a write up from Prima about this being a great scale, especially for beginners, I figured I'd give it a shot. I'm so glad it did. It's a great product, easy to use, and very affordable. I would recommend for both beginners and experienced coffee makers.

Best Scale For The Money

For $40, this scale exceeds expectations. Specifically, I'm glad it does not have an auto-off function. That frees me up while I'm brewing to focus on brewing, not keeping the scale on. It is a little bigger than I like for a personal use scale, but the rest of the functionality makes it worthwhile. I also like that you can flip the casing over on top and brew on that. I don't know how many scales I've ruined by an accidental overflow, bump of a full mug or mis-placed water stream. This keeps it relatively idiot-proof. I do wish you could turn off the beep.

Mixed feelings

I had been eyeing this well-reviewed, wallet-friendly scale for awhile (was trying to decide between it and one of the much more expensive scales available from Prima) and then unexpectedly received it as a gift. I have mixed feelings about it. It is large and bulky, not terribly attractive. But my issue is mostly with the accuracy. Unfortunately, I don't have another scale or any weights to test it but I can tell you that in my experience using it the readings seem to fluctuate. For example, I will sometimes go to weigh out my grounds, wait for the reading to settle, then wait a few more seconds just to make sure it registers, and then as I move onto other steps in the brewing process (not touching the scale) I will notice it either going up or down in weight. Also, if I brew on the scale and tare after my dripper is all set up, then pour my grounds in, the reading is different than when I weighed just the grounds (taring after I set the measuring cup on the scale, before I put the grounds in) And if I happen to accidentally bump it, it goes crazy and shows me crazy weights - which is inconvenient, because I have bumped it in the midst of weighing grounds and then had to pour the grounds out, and then back in again, more than once. The good: I like that you can use batteries or plug it in and that you can easily adjust the unit of measurement (grams, ounces, pounds, pcs function) Overall, I think that it is a decent scale (assuming the weights are accurate..) but I personally would prefer the extra functionality of the other scale I was contemplating, as well as the thoughtful design.

Great while it lasted

Had it for about two weeks and then it died. I liked that it was to read but it didn't seem to last. Maybe I got a bad one? Just ended up getting another Hario scale.
