I think you may be talking about the pre-diluted tobacco absolute. That stuff is incredibly strong. The standard PA tobacco's are mixed with that cotton candy sugar that everyone uses now and is a bit less potent and much sweeter.
No, it says "Tobacco Flavor" on the label. I also have some Perfumer's Apprentice "Tobacco Base." Of course, when it comes to flavor, everybody's tastebuds are different.
To put in perspective, a comparison of the amounts of different tobacco flavorings that I use:
Seedman's Fire-Cured Virginia (from Blue Mist): 3%
Rob's Blackjack (Blue Mist): 1.5% (sweet)
Tobacco Flavor (Perfumer's Apprentice) .5% to 1%
Tobacco Base (Performer's Apprentice) .5% to 1%
Shade (Flavour Art) 1% to 1.5%
So with all of these, the most I use is 3%. One way to convert my taste to yours might be via proportion. If, for example, you have also used Rob's Blackjack and found that you needed 5%, then the amount of Tobacco Flavor you should try would be ((5/1.5)*(.5+1)/2)) or 2.5%.
