No visible oil droplets; a light northern Italian style roast.
I tested a range of doses (16g to 20g) and temperatures (roughly 198-202F) on my Vetrano (an E61 HX machine) and Spaziale S1 (a double boiler). At higher doses and temperatures, I tasted predominantly vanilla, almond, leather, and some chocolate. At lower doses and temperatures, this blend was noticeably more fruity, dominated by sour cherry, vanilla/almond extract, and chocolate. These were "traditional" 45-50ml doubles (sorry, Chris

There were subtle differences between the HX and DB pulls. This may be due to brew temperature profiles (humped HX vs. flat DB), basket shape, and perhaps a slightly lower dose (~1g) in the 53mm S1 basket. Some have reported problems updosing the S1. I had no such issues:

In general, I preferred the S1 pours as straight shots, and the Vetrano pours with milk. Both were improved (IMHO of course) by a small amount of sugar, which seemed to enhance the sour cherry notes.
An interesting blend, and one that I will continue testing over the next few days. Thanks, Mike!
