Topic: New Espresso Blend (3 msgs / 66 lines)
1) From: cationic
Here's my newest (and best - so far) blend for espresso shots:
(Measured by volume, before roasting. "1 part" is 4 oz (1/2 cup - volume!).
Roasted separately, except for the last two, which were blended green and
then roasted. The Brazil was roasted in two batches.)
2 parts Brazil Serra Negra - roasted fairly dark (2nd crack + 2.5 minutes)
1 part  Guatemala Huehuetenango Catinil - dark (2nd crack + 0.5 minues)
1 part  Sumatra Mandheling Special Triple Pick - dark (just into 2nd crack)
0.5 parts Papua New Guinea Purosa and
0.5 parts Indian Kaapi Royale Robusta - fairly dark (2nd crack + 1 minute)
Precision Hearthware
Rocky Grinder
Silvia Espresso Machine, 22-25 sec shots, double shot filter
Even though I didn't wait more than 3 hours after roasting before I made
the espresso shots, I got unbelievably good results. Abundant crema (dark
reddish brown), perhaps not the most crema I ever got, but up there with
the best. Sensational smoothness in the chocolate notes, a bit of almond,
and a touch of floral and fruitiness. No bitterness or high acidity; nice
high body, excellent mouth feel.
I really like this blend a lot. It emphasizes all the dimensions I like,
and it minimizes the ones I don't.
Feel free to comment and offer suggestions for improvement!

Rafael

Raf.. sounds like a good one.  ThanX for sharing eh.
I guess, Thomspon, I need to order some beans....  :)
Rafael, did you record the total roast times and the times the cracks appeared?

Gonzo,
My record keeping leaves a lot to be desired, but here is what I remember.
(Also, I do tend to walk away from the roaster more now because I got to
know it a little better... I do not leave it completely unattended, and I
am roasting outdoors, so I'm being safe. But, I don't stand there and watch
the whole process any more.)
Outdoor temperature was 65 to 68 F, mild to strong breeze, low RH.
First crack happened at about 3 to 3.5 minutes. 2nd crack at about 7 to 8.5
minutes. Longest roast time (total) was about 10.5 minutes. Shortest was
about 9 minutes.
I hope this helps!
Regards,
Rafael
