Plain-jane drip brewers beware, the Breville Precision Brewer promises an extended featureset more robust than any brewer on the market. The Precision Brewer starts with a dedicated Gold Cup setting that meets all standards for SCAA certification, including a brew temperature between 198 and 204°, a total brew time under 8 minutes, and an even wetting of the coffee bed. Other dedicated drip brew modes include 'fast' for a quicker brew that raises flow rate, and 'strong' which lowers it. You also get a 'My Brew' setting that gives you direct control over bloom time, flow rate and temperature. Each mode accepts brew sizes between 8 and 60 ounces, and lets you adjust for #4 cone or regular flat bottom filters (or the included goldtone reusable basket filter). This extra-flexible basket design also opens up brew options not usually possible in regular drip brewers, including automatic cold brewing, over-ice brewing, and settings for automatic pour overs with a V60 or Melitta in place of the drip basket. If you're a lover of multiple brew methods, the Precision Brewer's multi-use design is sure to impress.

Features and Functionality

  • Gold Cup Certified - The Breville Precision Brewer recently passed certification as a Gold Cup Brewer by the SCAA!
  • Fast Brew - Need your coffee a little faster? A dedicated fast brew option speeds up the flow rate for quicker cups.
  • Cold Brew, Ice Brew - Also packed in are brew settings for a 12-hour cold brew steep, or a hot brew with half the water for ice brewing.
  • Single Cup - A dedicated single cup option lets you brew up to a 20 oz. mug of coffee for those on-the-go mornings.
  • Cone or Flat Basket - The Precision Brewer comes with different baskets for different brew sizes, and includes both a flat bottom metal filter basket (paper filters also fit) and a #4 cone basket.
  • Programming - Customizable settings for bloom time, temperature, flow rate, and auto-start programming give you extra options to find your favorite brew.
  • Stainless Steel Carafe - Coffee stays warm for ages with the insulated stainless steel carafe.
  • Quality Coffee - Calibrated to brew at the SCAA-rated 198-204°, the Precision Brewer makes a seriously good cup of coffee.
  • Versatile - Drip coffee? Check. Single cup? Check. Cold Brew? Yep. Iced Coffee? Good to go. Multi-use brewers are awesome.
  • High-capacity - Being able to brew up to 60 ounces of coffee at a time is fantastic for guests, parties, or just the caffeine-deprived.
  • A Little Tall - Standing at just under 16 inches, the Precision Brewer is a little tall to fit under some cabinets.
  • Options Abound - While the amount of functionality available on the Precision Brewer is truly incredible, it's definitely not a 'simple' brewer. You'll be spending some time finding your ideal settings.

I can't decide between this and the moccamaster. How about a crew review comparing the two to help me decide?

Best Answer: Good idea! Stay tuned.

What's the pros/cons of this machine vs the Moccamaster?
A shopper on Sep 10, 2017
Best Answer: Great question!

Functionally, they both brew drip coffee excellently (both are SCAA Gold Cup certified).

The base Moccamaster has the benefit of a glass carafe and a mixing tube in the lid. The Technivorm is also easier to use (2 switches). That said, programming options are nonexistent, and you have limited options for brew size based on the model you are looking at.

The Precision Brewer is pretty much the polar opposite of the Technivorm. Lots of programming options, including options for single cups and other brew methods. You can control automatic programming, temperature, flow rate, bloom etc.—at the cost of more involved setup.

How well does the pour over feature work? Is the V60 adapter included?
A shopper on Sep 17, 2017
Best Answer: The pour over adapter is not included, however you can register your Precision Brewer online (there is a unique code in each box) and receive the adapter for free! I believe this promo lasts through the end of 2017.

Is the optional glass carafe included or is it a special purchase? Will you be selling the glass carafe?
Rolando G on Sep 10, 2017
Best Answer: I asked Breville customer service. The glass carafe model, with warmer pad will not be out until April 2018. Like TV, they are two different models.

How does the Breville Precision Brewer compare to the Grind Control in terms of both taste of coffee, controls and function? I love the Grind Control, but like its predecessor, it has some technical difficulties.

Best Answer: I much prefer the Precision Brewer over the Grind Control. You get much more control over pretty much every brew parameter (including flow rate and temperature) with the tradeoff of needing a standalone grinder.

What paper filter is recommended for the Cone Filter?
Dennis M on Sep 27, 2017
Best Answer: I just opened it! It does not say, but I have some #4 from my Technivorm Moccamaster, which appear to fit fine. It come with flat and a mesh basket. Anxious to try it.

Sorry but the "auto start programming" phrase is a bit fuzzy given all the optional brewing parameters. Can I set this puppy in the evening to make coffee automatically at a desired time in the morning?
A shopper on Oct 25, 2017
Best Answer: Yes. We do almost every day, and it is super simple.

This unit looks like a game changer in a sector of the coffee maker market that is poorly served but what is currently available - where form following function is totally absent. Is there any reason that it does not have a convection funnel like the Wilfa or Technivorm? This seemed to be a logical way to get an improved carafe of coffee.
Luigi on Sep 11, 2017
Best Answer: I agree, a mixing tube in the carafe would have been a nice touch. My guess is that they skipped it to keep the carafe more insulated

Is the included carafe truly 60oz capacity??

Can you use the Pour Over setting to brew directly into a cup without actually using a V60/Kalita/etc.? Looking to brew coffee directly over ice, not brew first and then pour.

Move Over TechnivormReview by UVAHOO
I had the Technivorm Moccamaster KBT-741 for 2 weeks and chose to return it after receiving the Breville Precision Brewer. Breville definitely stepped up their game this time around and I am thoroughly impressed. The Breville feels very sold and not flimsy and plastic laden like the Technivorm.
I definitely like the customizable options on the Breville. I was concerned because everyone rants and raves about the quality of the coffee produced by the Technivorm. I will say that I think they both are fairly even. What I did notice is that the Breville does a much better job of water dispersion over the coffee grounds compared to the Technivorm. The Breville truly saturates each and every ground whereas the Technivorm didn’t cover all the grounds.

I think Technivorm has been dethroned here and it’s time for them to go back to the drawing table and up the ante. No, I don’t work for either company, just a true coffee nerd. Prior to this, I was always using an Aeropress which still make the best coffee in my opinion. It just became too much work when I wanted to make 2-3 cups.

An excellent product. Thanks, Breville!Review by Bruce
I'm a long-time French Press Dark Roast kind of home brewer. I've grown interested in a more refined method of late. First step was to buy a Baratza Virtuoso grinder and I love that machine. So then I started looking at brewers...

Just as I was about to pull the trigger on the Technivorm I saw that Breville had just released the new Precision Brewer. I was seduced by several traits of the Breville:

- Custom Settings! You can tinker with Bloom Time, Water Temp, Flow Rate...
- 60 oz Capacity! Great to be able to get a bit more that 40 oz in a single operation...
- The Thermal Carafe! And this is a good one (as is Technivorm), though the Breville is necessarily larger...
- Can make small brews! I've heard Technivorm shines at 40, but not the best in small doses... The Breville covers from a single cup up to 60 oz...

I've now been using the Breville for only several weeks but I can say some things about it.

- Build Quality seems great. I cannot find a flaw.
- Machine is large (okay by me).
- Operation is straightforward (cept maybe that setting for cone vs flat). Basically, you can do a simple process or you can get into settings and stuff. Much like an excellent camera with both Full Auto and Full Manual settings.
- Operation is quiet and unremarkable.
- Fun factor. This is great - I can play like you would with a pourover, but with a full pot!
- Fun factor. Oh, yeah, I mentioned that. I love the custom settings capability!
- Results are just excellent. Smooth, round, full-flavored coffee. Ahh!

- one tricky note is that when you switch from cone filter to flat basket filter method you must drop into settings to change that (I suspect the flow rate is different at the least). I made a 60 oz pot without changing that setting (I forgot) and it was undrinkable. Breville says use the cone up to 40 oz. I've cheated that up to 45 and it is fine. I suspect if you went slow flow rate in custom settings you could make even larger pots with cone filter...

First try: I started with a 20 oz brew of Peet's Major Dickason's decaf since I got home and had a new brewer to try in the late day. 33 grams ground at 24 on the Virtuoso. Used a white Technivorm no 4 cone filter (rinsed with hot water in the cone) and the built in GOLD brew setting on the Breville.

First result: A really excellent rendition of a Peet's blend that I'm very familiar with. As good as any and better than many cups of Decaf Major that I've been served in a Peet's store. Just about perfect! On the first try!

Next steps: I'm generally making a 40 oz pot using a paper cone filter. Have tried several different roasts and getting very nice results but definitely want to tweak settings for different roasts. For some reason, different coffees need a different process to avoid an over or under-extract. Full disclosure: I'm an engineer and I like messing with settings and process to get just the right result. Many just won't need these manual settings, but I love that (esp since I've been playing with my French Press methods for years).

This morning: I went full custom with a half caf mix of Peet's Decaf Major and Peet's Italian Roast. 40 oz. brew using 68 grams coffee ground at 24 in the Baratza. Custom settings of: Bloom Time 45 sec, Temp 92 degrees C (lower than some would set), Flow-Rate Medium, Pourover OFF. This resulted in a fantastic pot of coffee. Round, full flavor, perfectly smooth and no hint of any under or over extracted taste - no bitterness, no sourness, just what I want.

I've contacted Breville for the pourover attachment and will see how that does. I suspect that I might still want to do pour from a kettle now and then for a single cup, but I don't really know. This Breville is really good for small pots, like just a couple cups of after-dinner decaf.

Summary: Well-built, fun to use, great coffee and so far completely trouble free. Is a faster process than messing with a press in the morning and gives me a consistently excellent pot of coffee. I am very, very pleased with the product. Well-done, Breville!

Really good brewerReview by Steve
The BPB has an excellent thermal carafe (better temp retention than Bonavita IMO) , uses a pump and PID controlled temperature, and has a 'bloom' feature to pre-wet the grounds. One important consideration is that there is both a basket filter holder for 40-60oz, and a cone holder for 40oz and less. The bloom-delay, the water temperature, the rate of brewing and the pourover settings are programmable in a single 'my brew' personal setting.. The 'gold 'SCAA setting is only available for 40oz & cone filter. There are 'fast' and 'strong' settings which apparently modulate the water temperature & flow rate and perhaps the bloom delay.

The BPB makes a thumpy noise while pumping water, similar to an espresso pump, then announces the completion with a few beeps (programmable volume).

I've found it educational to adjust the temperature and observe the flavor impact but the ~3C range I prefer is no better than the 'gold' setting. I've use the 'slo' waterbrew rate a few times, but this generally results in modestly inferior flavor.

I've also used the 'cup' method to brew small pots (20oz and less) and this works quite nicely, and can brew directly into any container. I have not used the cold brew or hot iced coffee features yet.

The BPB is somewhat sensitive to my relatively hard water, and has thrown 'Err7' several times . I expect the same issue has occurred with my other brewers, it's simply that they lack the sensors to report an error.

Overall I have to rate the coffee produced as good as the Bonvita, and with a lot more options wrt volumes, and other brewing methods. The price is justifiable for those who will actually use the extensive features.
