re: Homebrew: Extract IPA is too dark

LME will darken over time. Depending on where you got it from, it may have been old. Also, (not sure how long you've been brewing, so you may already know this) You should always take your pot off the fire when adding extract as it will drop straight down (almost) and can get scorched. Even after you mix it in well, you want the fire just hot enough to produce a slow rolling boil. A rapid boil is going to darken the wort.

There are lots of sources that will recommend only using light extract. I have gotten to the point where I stick with extra light or light only, unless the beer I'm brewing is supposed to be a stout/porter color.
