One of my early beers was an extract amber ale. At the time I really dug it. I impressed myself with it as a novice brewer. I've been seriously toying with the idea of re-brewing it ten some years later, perhaps revising the recipe a touch based on having more brewing experience. Part of me would really like to see what comes of generally following my original recipe. A couple of things feel like they're holding me back - - 1) recalling the flavor and mouthfeel of it I know now that I probably didn't oxygenate well, under pitched, and it was under attenuated, though somehow at the time I thought it was delicious nonetheless, but with a re-brew I wouldn't recapture my less stellar brewing technique so maybe couldn't replicate a similar beer; 2) with passage of time and palate training I've become more picky and my tastes have changed as well. I'm leaning towards giving it a go later this year.
