I’ve had it, yesterday. I live near Prufrock and often go there to sample their “guest” espresso and buy bags of ultra-light roasts from the likes of Manhattan and Wendelboe.
I had the new Grifone blend on its own, rather than alongside a Red Brick espresso pulled from their Victoria Arduino pump machine, as I know what the latter tastes like. I found the Grifone a little disappointing: almost no crema (which is odd, I believe, for a 50s-style blend) and with little texture. The first sip was Italian-bitter, the middle one lacking complexity, but the last – when I had let the liquid cool down – was a rather interesting blend of Yemen-type flavours with Central and South American ones. (That’s the best I can do for descriptors.) I’ll return again to Prufrock to have another go.
They are grinding with a Mythos which they have set to produce drips from a spouted portafilter in 9-10 seconds, when they lift the Faema lever. I forget exactly what the brew ratio is but it’s something like 14g in and 35g out in around 38 seconds. But I’ll have to confirm those numbers when I return.
I tried to buy a bag of Grifone for use at home, but they were sold out.
