Gonzo’s Biggdogg Vanilla Porter

Michele smuggled this back from her recent trip to Kalamazoo MI. 

A smooth and sweet porter with strong vanilla flavors, starts good but finishes kinda watery. 7%ABV. 

I found it odd to see on the label that “carmel color” was added along with “artificial flavor”.  Why was added color needed?   I assume the added flavor was vanilla,  but maybe not…
