Hoppy Blonde Ale

About a couple weeks ago, I re-pitched the yeast from the spiced blonde ale (see previous entry) and brewed a hoppier version without the lemongrass and pepper. At bottling time, it tasted more phenolic than the first batch, but I suppose that's to be expected when fermenting at near 85 degrees! Seeing that this batch seems a little higher in gravity than the last, I'll probabably wait at least a couple more weeks before I crack open a bottle. Having tasted the spiced blonde, I'll probably go back to adding the spices, they add just bit of complexity that can't quite be figured out...

First time using sparge arm. Didn't realize the jump in efficiency that I had hoped, but the sparging process was easier and could left alone most of the time. I think 13.5 pounds of grain would fill the lauter tun to capacity, while still leaving room for the sparge arm. Added four ounces of Cooper's DME to boost gravity. Diluted the 3.2 gallons from the kettle with an additional quantity of water to make up five gallons. I'm not happy about my low effiency, but I guess that's what I have to expect if only sparging with enough water to boil 3.5 to 4 gallons instead of 5 or 6.
