When I say aroma, I mean nose only. When I say flavor I assume people will understand that includes both taste buds and retro nasal whatever, and if they dont... probably they still know what I mean by flavor.
So, you can have a beer with hop bitternes and extremely minimal flavor or aroma. You can have a beer with very little bitterness and lots of hop flavor but no aroma. And you can have a beer with minimal bitterness, moderate flavor, and lots of aroma. And almost any combo of these.
We also run into the issue of defining this depending on style. For instance, people will try a glass of Munich Helles that only had a half ounce of Magum at 60 minutes, and was gell fined, and say "Way too much hop aroma." The same person will try a Pale Ale that had 4 ounces at a 170 whirlpool, and gell fined, and will say "No aroma, the gell fining stripped it all."
