Fred Jerbis Italian Amaro 16 is definitely a Gateway libation to Fernet. It's kind of like an Amaro growing wiser as a sophomore in college, ready to ace final exams in the Amaro realm.
It is definitely Pine forward, with other Alpine notes like sage, Thyme and rosemary. It's more woodsy than rooty, and more astringent with little to no sweetness at all. It's starting to delve into that realm of camphor and Eucalyptus as well.
You can hear me talk more about it here:

If you've maxed out your Amaro palette, and want to progress to the next level, but aren't quite ready for fernet branca, give Fred Jerbis a try.
I like to mix Fred Jerbis with the Italian Amaro called Foro, and in essence, make an unsweetened "root beer" type beverage. Either are great on their own, but together make a nice powerhouse.
