Everytime I drink a beer from a brewery I can't help but notice my beers lack that crisp and clean flavor you get on a professional level. Not that my beers are cloudy or still green it's as if the homebrew has more body or something extra within. Is this a result of not filtering my beer? Its Iike I am missing some malt backbone at times.
It could be a lot of things. I agree wholeheartedly with what @mongoose33 said.
Brewing is process-driven. It's basically manufacturing of beer. In manufacturing of most products, there are certain things that are considered "best practices". That's where you start.
Best practices IMHO:
- Cleaning/sanitation is obvious. If you can't do this, why even brew?
- Water quality / chemistry - if you live somewhere where you water is "good enough", good for you. If not, invest in RO and added salts.
- Yeast health - adequate numbers of healthy yeast (starter for liquid or proper amount of dry yeast).
- Fermentation temperature control - IMHO it is key.
- Proper transfer procedures (to avoid O2 uptake after fermentation).
As for your own situation, obviously if you haven't gotten #3-5 down, that's where you start. But if you've been around this site a few years, I'm going to assume that you've gotten there. So you might need to look at water chemistry.
My own story: I started brewing in 2006. I had items #3-5 fully nailed down and my process was pretty good by 2008-09 or so. My beers were very good. I considered them "almost" commercial quality, and neutral observers (competition judges, knowledgeable homebrew club members, etc) all were very complimentary. But they weren't quite "there" yet. My dark beers were great; the lighter-color beers (what I brew more often) just weren't perfect.
In 2015, after 9 years of brewing, I switched to RO water. After 9 years, I detected an IMMEDIATE improvement in the quality of my beer. No process change other than water, and those light-color beers which had muted malt flavors just suddenly popped. 9 years and I was honestly blown away by the change.
I think given that I'd worked out the rest of my process to meet most "best practices", that changed moved my beers to what I would consider commercial-quality, up there with what you'd find at any solid craft brewery.
So if you think you've knocked out the low-hanging fruit, I'd take a look at water.
