Hello.
You didn't mention what sort of tobacco flavor you are seeking: cigar, cigarette or pipe.
Here's a link to the most authoritative thread on the web of tobacco eliquid, most notable Naturally Extracted Tobacco. On the first page, you'll find a listing and ranking of the most notable vendors:

Some of my favorites are Legend, Huntsman and Heavenly ARMY from Heather's Heavenly Vapes. And I can second the recommendation for Ether Vapes from the sample I have tried. And if you like RY4 type blends, give Dirty Dutchman from ITCvapes a go -- very flavorful chocolate/caramel tobacco and one I can't seem to stop vaping of late.
