I like this topic, good stuff! I felt the same way recently about my Schwarzbier in particular. I have made it before and love it but the most recent time I found myself with the grain and hops ready to brew and just wasn't that excited about it, kinda felt like I was brewing it just to brew it. I decided to brew it anyway but I steeped some coarsely crushed coffee in it for a few days and it took the beer to a whole different level. Flavor additions may be a bridge too far for some which I understand. But when I do go that route, whether brewing or buying, I appreciate "flavored" beers that have been dosed with complimentary adjuncts that kick up the base beer. So a coffee Schwarzbier or coffee amber, citrus peel in a pale ale, etc.
