I had long thought of, since getting the Evo, having a dedicated thread to share my coffee experience. The laziness got the better off me. I also didn’t have much recounting the journey stories like experienced folks like Dave, dfk41, Systemic, MRS, Jake and many more. Jake’s recording of his journey is beautiful. With the duo due to be delivered soon, it’s about time I take a leaf out of Jake’s and have a thread sharing the user experience of using the Duo the way it was originally meant to be and designed for. Swapping the burrs seem to be quick and easy. Can one really integrate it as a part of a daily routine? Or, would it become a faff over time - what ever may be the reason ? I make 3 espressos in the morning for 3 and at least a filter or two for self during the day. There may or may be any decaf espressos in the evening. I think users like self are perfect candidates for the duo. I have every intentions of swapping the burrs - there is no reason not to otherwise. It remains to be seen if I will enjoy using the dual burrs daily or get bored swapping daily after the honeymoon period - 3 months! I will post my views as I experience it. There will not be any reviews or comparisons for three reasons. 1) I can’t be asked, 2) Tom, I am sure, will do the honours as usual and 3) I can’t afford to buy :-) I do want to know how I will like the espresso (taste wise) from JX pro vs the duo. I mostly drink medium light / light. I take full 2 mins to grind 17g. One thing for sure is I won’t be missing the hand-grinding part! 😁 More later!

cant wait for you to get hands on, its about time they hit the hands of more real world users, im sure you will love the grinder, im finding 6 to be a good starting point with beans for espresso and then 30-40 range with filter, which i dont drink alot of tbh,

@"Cuprajake"#p48288 Great shout. I will start at those ranges Jake.

Thx to @"dfk41"#4, grabbed a few KGs of cheap beans from Amazon for £30 to season the burrs sets. Supposed to be light / medium roasts [URL=https://i.imgur.com/on0KllQ.jpg][IMG]https://i.imgur.com/on0KllQ.jpg[/IMG][/URL]

think i ran about 500g through, got bored and just used it lol

@"LMSC"#p48290 Would be terrible if you tried drinking it snd enjoyed it!

I think Niche suggest this, but if you can, once unboxed, leave it to come to room temp which takes an hour or so. If you touch it, it will be freezing cold which is just a by product of the delivery system……enjoy matey!

@"dfk41"#p48297 Yeah! I saw their video. Thx mate.

> @"LMSC"#p48286 Swapping the burrs seem to be quick and easy. Can one really integrate it as a part of a daily routine? Or, would it become a faff over time - what ever may be the reason ? You will find that while waiting for the kettle to boil, you can swap the burrs, why not to get extra good filter as opposed to just using the espresso burrs.

@"DavecUK"#p48306 Indeed. No point in getting the filter burrs set otherwise. Let’s see how it goes over time 🤞

Coffee with Duo

tompoland

Cuprajake 100%. A very valid inoffensive option.

Lots of ways to get an inoffensive espresso. It’s Nespresso’s specialty.

Trouble is, most of us are here because at some point “inoffensive” ceased to satisfy.

And that’s the challenge that I see for the omni burrs. OK at both espresso and filter but brilliant at neither.

There is clearly a place for them because SSP Cast and Lagom Mizzen burrs are the burrs of choice for many.

And TBH burr geometry remains a complete and total mystery to me. I just know that I enjoy the bright intensity of an SSP Espresso 64mm burr for light roast espresso and the full bodied choc-like notes from a Gorilla Gear 64mm burr to the inoffensiveness of the SSP Cast burr.

Cuprajake

It’s probably because people want to drink super light, realized it’s battery acid then change burrs to make it more palatable ……

Instead of moving to a medium roast 😂

Jokes aside coffee in general has way too many variables in it, you could make two identical brews if you had lab conditions. The law of sod comes into play.

Day 16

A different start to the morning routine today as I wanted to have a filter as a first thing in the morning.

So, changed the burrs to filter and ground the usual 15g of Dog n Hat Tim Wendelboe’s Honduran filter coffee beans on 12% Kruve 400 grind reference on the Duo. What a coffee this has been. The filter brings a different characteristics of the Honduran filter roast. More on the V60 thread.

Enjoyed drinking the V60 brew and swapped to
espresso burrs. Not satisfied with a small cup, I straightaway pulled a shot of Crankhouse Colombian Yenni at 6 mark on the Duo. It became a turbo shot at 20s and yet very good to drink. I will settle down at around 5-5.5 and leave it at that.

I think I will keep the rest of Dog n Hat Norwegian Tim Wendelboe and reserve at least a half of Crankhouse’s Colombian Yenni for brewing.

There would at least be two more burrs swap later today. 😊

LMSC

Another burrs swap for a lunch brew. Made another V60 of the same Dog n Hat Tim Wendelboe Honduran filter roast. This time at 9% Kruve 400 on the #31 Mark on the Duo.

Excellent coffee like the 12% counterpart! 😊

LMSC

Day 17

Another filter start for the day, which means there will be 4 burrs swap for the day. The overnight burr set will always be espresso for decaf reasons. Two swaps - filter and espresso - have already happened this morning.

Made a V60 at #17 mark on the Duo for the usual Kruve 400. I am still sampling two grind references; and, one at the #17 mark and the other at #31.

The filter was Crankhouse Colombian Yenni. Excellent coffee giving dried mango flavour.

Swapped the burrs for espresso, when my family came down from bed for morning coffee. Made two shots of Foundry’s Rocko Mountain and decided to help myself with a Black Americano.

Opened Cartwheel’s Colombian Winton Benitez - Grape Fruit, Sherbet and Cane Sugar, 17.5g, 40.6g, 46s, pulled at 7 bars. Excellent coffee with grape fruit fruity acidity, sweetness and taste. The sugar taste came out straightaway throughout and also as after taste.

DavecUK

LMSC Clearly you feel it’s worth the small effort to swap the burrs to optimise taste?

LMSC

DavecUK Clearly you feel it’s worth the small effort to swap the burrs to optimise taste?

Yeah! It’s not a faff swapping the burrs so far. It’s worth it IMO.

The filter burrs compared to the manual grinder performs better - clarity and notes. I am sure it would produce a markedly different cups vs the espresso burrs.

Once, I finish sampling the filter burrs’ grind references, I will sift and get similar grind references on the espresso burrs. I can then compare the filter vs espresso burrs for brews.

DavecUK

LMSC You should be able to taste the difference almost every time. I did many tests doing 2 simultaneous brews and it wasn’t hard to tell which was which (because one was always better).

LMSC

DavecUK Looking forward to it Dave! I would also like to see where do the grind references for 9% and 12% Kruve 400s would fall, should some one be interested. Thx

LMSC

@DavecUK - What’s the best way to keep the threads smooth, considering I swap the burrs twice a day mostly?

The grease isn’t going to last as much as in the case of most of the users.

Another concern is the life of the thread itself! Is there a risk of wearing out, with my frequency of the swap?

It isn’t smooth while loosening and tightening the hopper; It can be very tight, which does make me think the lube is wearing out quicker than expected, given the frequency of swapping.

The threads also become darker with fines say in couple of days. I am super careful while removing the burrs and dusting the fines.

DavecUK

LMSC It isn’t smooth while loosening and tightening the hopper; It can be very tight, which does make me think the lube is wearing out quicker than expected, given the frequency of swapping.

Just apply a little pressure to the centre cone when tightening or loosening and it will reduce a huge amount of spring pressure.

Cuprajake

Did yours come with a tube of grease?

Also wierd gourmet uses PTFE tape on the chrome hopper app to good effect

LMSC

Cuprajake It does! I am using the Molykote 111!

The PTFE tape is of no use for my use case! 😁

MediumRoastSteam Reading this thread I’m getting somehow sceptical!

About ? Could you explain ? 😁

MediumRoastSteam

indeed. I said exactly that a few days ago.

https://coffeetime.freeflarum.com/d/1851-coffee-with-duo/98

As mentioned in my post, I never had such problems. Reading this thread I’m getting somehow sceptical! 😊😂😂😂

MediumRoastSteam

LMSC - just the issues you are reporting… fines getting caught on the threads, worrying about wearing out the thread overtime, etc, etc. I suppose I’ll find out myself when mine arrives.

LMSC

MediumRoastSteam I am going to wipe it clean to ensure there are no fines, grease and observe for a week each - regular use like now and without swapping.

MediumRoastSteam

LMSC 👍 - if you grease it, don’t you risk fines getting trapped and stuck there, making a mess? I never greased mine.

LMSC

MediumRoastSteam I do think it does.

Their cleaning video suggest greasing lightly. Otherwise, it is sticky. The PTFE is ideal, but it doesn’t fit my use case 🤣

I wonder if food safe silicone spray would be a better alternative ? Does it work MRS?

MediumRoastSteam

LMSC

LMSC Does it work MRS?

No idea. I never used it.
