It also required a bit less grinder adjustment throughout it's 9 day life span at mi casa. Perhaps I just got lucky. Wouldn't be the first time.

I feel like you must have! I got a half pound each of Dolce and Vita to "christen" my Vetrano, and the Dolce was horrible all but about one time. Someone in another thread described the taste as "rubbery," and that definitely matched my expericence on most of the shots. I was so disappointed, but I haven't re-ordered it.
Vita was the easy one for me. It was consistently sweet, especially in the aftertaste, with very controlled acidity. It is surely one of my favorites after only 1/2 lb.
@ the OP: I would agree with the folks here--get enough of any coffee you buy to learn it better than the "1 lb sampler." 1/2 lb was not enough to really judge Dolce. I wouldn't avoid "tough coffees" in particular, and I wouldn't be afraid to try different blends some even while you are working on technique. It can be a fun adventure. But, definitely pick a main coffee to use as a reference, so you can observe how it changes, how it compares to others that you sample, etc. I don't think there is any need to worry if it is finicky. That might be a little frustrating for awhile, but in the end I feel you might learn more consistency faster.
I have a blend that is easy for me to get locally that I use as my regular coffee when I am not sampling. It is pretty much a classic espresso blend, stopped early in the second crack, low acidity, heavy chocolate, slight sweetness, classic coffee aftertaste... Anyway, I have been through 10 or more lbs with it, I think, on both my La Pavoni and Vetrano. I got into a huge rut with it awhile back where I was updosing to like 20 grams (in a synesso triple basket!), and hating it. Always these intensely sour pours that smelled horrendous. I ended up downdosing to 18, and then back up to 19 grams, and 19 was where it started hitting really nice. I have been sampling CCC's Toscano and Biloya lately and enjoying pours with a 21.5 gram updose. I am talking, almost no expansion room. I went back to my regular blend and tried that dose, but much finer and a lighter tamp than before, and got a wonderful shot, with similar flavors to the coarser, 50+lb-tamped 19 gram dose, but with much heavier body, and a richer chocolate flavor. That variety of experimentation (for me) definitely takes a lot more than a pound to figure out. I am sure I will continue to keep tweaking it in the future, too.
Good Luck, though you don't need any in your awesome neck of the woods.
