Depends on which Savinelli you are referring to:
ELR - very mild dominican; at one time rolled by the Fuentes...don't know if it still is; flavorful and creamy
Nicaraguan - medium-bodied, sweet nicaraguan tobacco taste, the couple I tried were a little bitter; well constructed
Fuerte - not very fuerte, medium-bodied, rich with some wood notes and toastiness; did not develop very much and burned hot
Oro - don't believe they make this anymore; my favorite of the line, dark, almost maduro wrapper; blend of nic and honduran tobacco; rich, charred flavors and coffee
There is also a special aged line of the Nicaraguan blend available some places. Hope this helps.
