We're closing out our five-part beer design run with a bang. The last gap on the Northwest Brewers Supply beer list is a Cold IPA, so that's tonight's target.

Is a Cold IPA just an IPL in new clothes? The BJCP hasn't said a word about it, so we dig into the difference.

We look at what went wrong with classic IPLs and can the Italian pilsner gives us a spark as we search for a crisp, clean, hoppy balance.
