ConclusionsVivace Dolce was something of a surprise to me. After all,
David Schomer has been hyping uber-precise flat brewing temperature profiles since the 90's. And at least one of my fellow reviewers found this to be a difficult, finicky blend.
In my tests, Dolce was a classic Northern Italian style espresso blend, with a balanced flavor profile and a wide range of acceptable temperatures and brew ratios. The beans are lower density than other tested blends in this study, with a level dose of under 16g in the 53mm Spaz double basket. Basket beading (first appearance of espresso droplets) was rapid, typically at 3 seconds. Crema production was prodigious, with a large cone from the bottomless PF.
Vivace Dolce: big crema, big cone.As noted, the flavor profile was balanced, moderately sweet, with adequate acidity but no outstanding fruit flavors. Medicinal/liquor overtones and some funky/earthy flavors are present, especially as brew temperatures increase. The acceptable brew temperature range was quite wide, with an optimum (on my gear) at around 91-92C. I preferred syrupy ristrettos with a small amount of sugar, and macchiatos with a small (1oz) amount of milk. Flavors were lost in larger amounts of milk. Milk chocolate and caramel notes emerged in milk at higher brew temperatures.
This blend was very drinkable after 5-6 days of rest.
In summary: a nice, albeit unexciting, Northern Italian blend. Best suited for straight shots (ristrettos) and small amounts of milk (macchiatos).
