Cuprajake I hardly time them except when the bag is new.

Have you timed your shot?
How does it taste? If you and your wife like them, I won’t bother. This is what matters.
When I open a new bag, if the timer shows up to 45s, I won’t bother unless I don’t like the shot or notice silts.
I pulled another shot this evening, exactly the same pour and time. On both occasions, I saw a tiny bit of silts into the cup. I may grind a little coarser tomorrow.
I don’t like doughnut extractions or beads on the screen taking too long (>10s).

You may be tamping too hard. Take a look at your distribution. I don’t think the screen or the basket matters. The Evo is forgiving. You don’t have to tamp harder.

We always use the IMS screen and the basket - for dosage reasons. I will swap the screen to stock and post the outcome. I think you are using the stock screen. Try the stock basket and the IMS screen, if you like. If you don’t have the IMS screen, I won’t bother. It doesn’t do anything to the cup.

Thx

Cuprajake

Thanks guys

Im waiting wayyyy to long haha

Cuprajake How many cups of coffee do you drink a day? Of the 6, I drink 4. The evening cup is mostly decaf.

Cuprajake

2-3 for me 1-2 for the mrs(milk)

LMSC

Cuprajake Jake, I haven’t changed any parameters since yesterday. Pulled two shots this am - the IMS screen and the stock screen. The shot timings are also the same. The cup - I can’t tell them apart.

As I said, it doesn’t matter if we use the stock or the IMS screen.

This shot is the stock screen on the Evo.

Edit :

It is the Ethiopian Haru from Thomson Coffee. I don’t like the beans. I will have to push it through. My daughter will kill me, if I make a long black with this this week end. Thank God, the chocolate point is in the post for her. The problem is I won’t be able to rest it.

Cuprajake

Thank you,

I may give the ims basket a second chance and dose less.

Another fine looking extraction

Cuprajake

LMSC

Very nice and even extractions. Well done. I guess, each shot lasted about 35s?

Did you loosen the grind a bit?

Cuprajake

Yeah looser. I didn’t time 😂🤦

LMSC

Cuprajake How were the cups?

BBritton

Very nice. Hope I can do similar once my Evo arrives. It’s been stuck in Indonesian customs since March 27. Frustrating dealing with a corrupt country and corrupt customs. I won’t get into all the issues but sure will be nice if it ever arrives and I can use it.

LMSC

BBritton Customs hold it for a variety of reasons. Our Bravo tamper was at the UK customs for about 3 weeks. DW. You are almost there!

Uh oh, I also have a Bravo tamper on its way. Seems like that may be round two. 😂

LOL luckily it were the Italian customs that suck

Cuprajake

I hate having stuff stuck with customs, the risk of damage really amplies.

My bom jesus came today, left in the bottom of my bin! Cheers royal fail!!!

I guessed at a grind setting, 18g in stock basket heres the result 28g out in around 32seconds.

Still getting slight donut 🍩 extraction 😒 thinking need to loosen grind a tad, or use this grind in the ims basket

What causes the donut?

LMSC

Cuprajake First, how was the coffee ? If you liked it, then don’t worry.

You did something correctly in the morning. Did you also adjust the distribution?

IMO, if you distribute the puck outward (a little more at the edges than at the centre), after flat tamping, you can get this. This compensates for the lack of extraction at the edges compared to elsewhere.

If you make the puck distribution absolutely even and tamp, you may not get this doughnut extraction - assuming the distribution in the entire basket is good)

You can test by pulling two shots. One, a good even all around distribution and flat at the top; the second, spread a little more at the edges.

As far as your shot is concerned, your shot time looks ok, unless you did not like the coffee.

Edit :

There was a video by the Decent guy on these two. I can’t find.

Cuprajake I always believed the donut was caused by the puck compressing more in the centre.

I’m not sure I follow: I would have expected that by increasing the amount of grounds at the edges, it would be harder for water to go there and thus more water would flow in the center of the puck, i.e., the oppposite of a donut extraction.

I would have expected donut extraction to be the result of having more densely packed coffe grounds in the middle of the puck

What am I missing? 🤯

Cuprajake

Coffee was ok yes, i reckon i can get it better

This morning was the ims basket

Im really torn as to which basket to use 😁🤦

LMSC

Cuprajake really torn as to which basket to use

Please go by the taste.

Another thing you may consider is, pull two shots - stock and IMS; cut a half of each with milk; serve your wife both without identifying the cup. and, ask her point of view.

The risk is you may not like what she chooses! 😁

Edit:

Alternative is you pull two shots, let your wife blind prep the cup and you do the blind testing. 😊

LMSC

Cuprajake honestly, I do not think the cup will be noticeably different!

LMSC

Eiffel Perhaps, a tiny mound at the centre!

Now you have confused the old man!😉
