i think it'd help if you posted some numbers, type of recipe, ingredients, gravities, bottling or kegging? How are you carbing them?
A lot of my early beers tasted similarly, but after carbing them they tasted more like i wanted them to. I'm still having trouble making hoppy beers myself. It just takes practice.
For example, the last one I did was an amber ale...
~50% 2-row
~40% munich 10
~10% crystal 40
Wyeast 1318 London Ale 3 (spec says its good for maltiness, which I like)
Cascade at 60, 15, and 5 min to make about 28 IBU.
OG ~ 1.055
FG ~ 1.011
This was a 2-gallon batch. I like making smaller batches since it means I get to brew more often and have more of a variety of my homebrews sitting around. I mash in my brew kettle which is an aluminum 6 gallon stock pot with strainer, and a grain bag in the strainer for easy grain removal. I mash in at 1.35 qt/lb with ph 5.2 stabilizer and 1/4 Campden tablet, conversion at 152 or as close as I can get, then batch sparge. I get 70-85% efficiency.
For the amber ale, I kept the fermentation between 60F and 70F for the first week, then let it sit for another 2 weeks at room temp (about 72-75F). Bottle carb by racking into a sanitized plastic jug with the appropriate amount of boiled corn sugar & water, let sit for 30 min to properly mix, then used a sanitized funnel to pour the beer from the jug into each bottle (I find it easier this way with small batches).
The bottles carb for 2 weeks, and then I start testing them once or twice a week by putting them in the fridge for 1-2 days and drinking. They seem bubbly enough, but don't have more than 0.5 inches of head that disappears within 15 seconds.
I also think it's interesting that they hydrometer samples tasted a lot more like hops than the beer now tastes.
Anyway, this is the process for most of my beers other than the fact that I tried a high protein rest at 132F for 10 min once to see if it had any affect on the head (nope).
I'll ship someone one of these to try if you want (especially if you're close to chicago or evanston), and if you think it'll help. Just PM me.
