I "finally" had a batch I couldn't stand to drink...it was a Bohemian pilsner for which the brewday and fermentation had gone flawlessly. Except for one thing.
As I was putting the aroma hops in for a 10 minute boil--some pelletized Czech Saaz hops--I thought, "Hey, those smell way more grassy than I'm used to for hops."
And then I thought, "Meh, what's the worst that can happen? It will probably just boil/ferment out, and be just fine."
Oops.
The cooling wort smelled like a freshly mowed lawn.
The fermented beer upon kegging smelled like a freshly mowed lawn.
The carbonated beer smelled like a combination of grass and a touch of vegetable and nothing good could possibly come of that.
Lesson learned! Next time, I'll trust my instincts when adding ingredients. If something seems off, I'll do a quick-change for something better, even if it means I go off-style! (and I suppose this is also a classic example where unwavering adherence to "authenticity" is woefully deleterious to my final product).
Details on the pilsner at my blog...
