I brewed my first batch of beer, an attempt at a porter, and the product tastes overwhelmingly grainy. It's like drinking carbonated wort. Perhaps we ground the grains too fine? Or could it have been that I mistakenly left the beer in the plastic bucket for the entire fermentation right up to bottling (as opposed to transferring it to the glass carbuoy)? Just wondering if anyone has suggestions on where we may have gone wrong. Thanks!
