Do we know for certain that the ascaso I-2 grinders have Tre Spade burrs?

Hi Christos,

I do not think the Ascaso conical burr looks like the TreSpade burr in my grinder.  Here is what mine looks like:

I chew coffee beans with my teeth while gargling with 195 F water to enjoy coffee. What is this "coffee brewing" device you speak of?

Many thanks for the answer Eric.

My question arose from my attempt  to compare the Isomac Maccinnino Prof. with the Ascaso I2/ i-mini(I2).
My previous understanding was that the:

Isomac,
Ascaso (Innova)  i2 & i-mini,
Iberital mc2,
Lelit PL53,
Nemox Lux

have the same burr set (6 coarse channels as opposed to 5 for the Tre Spade) but I got really confused after reading Jim Schulmanís comments about Isomacís inferior performance at the following link:
Click Here (www.home-barista.com)

It seems to me that the only grinders which have Tre Spade burrs should be the La Pavoni PGC and the FACEM Il Macinino (similar to La Pavoni) with Isomac and Ascaso grinders sharing the same burrs.  
Please correct me If I have understood something wrong here.

I found this vendor with a photo of the Isomac burrs - looks like the Ascaso set:

Click Here (www.espressocare.com)

Which look the same as the Lux burrs from this article - looks like the Ascaso set:

http://www.coffeeco.com.au/articles/sunbeamgrinder.html

Here are some great photos of a PL 53 in this first look type review - looks like the Ascaso set:

http://manseekingcoffee.com/2010/07/09/lelitpl53/

And some photos from this forum thread showing similar burrs in the Iberital MC2 - looks like the Ascaso set:

The Burr in the Ascaso looks a lot like the burr in the Baratza Virtuoso too.

Click Here (www.baratza.com)


I think you are correct Christos - these machines look identical under the covers.  

The LaPavoni PBC/PBG and the FACEM Il Macinino look identical too. The LaPavoni PBC I have uses a spiral shaped burr similar to the shape of vintage hand mill burrs and the Baratza Preciso.

Hi Eric,

Thank you again for all the effort you put for a such a comprehensive answer.  I found also some older posts of yours here in CG relative to the discussion here. They were very informative too.

I did some searching regarding the Baratza Virtuozo and Preciso burrs and I think these should be classified into a different category as they have a larger diameter. They are 40mm whereas  ascaso-type and Tre Spade burrs are 38mm.

Hi Christos,

Thanks for your kind words. You are correct of course about the Baratza Virtuoso burrs being a larger size burr set.  I wanted to include the link since the shape is very similar to the Ascaso burrs.  In fact the highly regarded 68mm conical burrs found in the Pharos hand grinder and some Large commercial conical espresso grinders have the same shape:

Click Here (www.home-barista.com)

It is interesting that the 68mm conical is so highly regarded yet the same burr pattern when compressed to a smaller 38mm size becomes "unsuitable" for espresso.  I question the validity of the theory made in the H-B thread you link to here:
