After my last batch of this ended up all over my basement floor, I wanted to rebrew it at the earliest opportunity. Today I got the chance.

Exactly the same as last time, only I've bumped up the batch size to 30.5 liters, which should give me 26.5 liters (7 gallons) of finished beer. Because my kettle can't hold all of that wort, that required a high-gravity partial-boil approach that gave me wort I could put into two 5-gallon carboys and dilute with water. I also had to increase the proportion of hops, so as to get the same amount of bitterness in a high-gravity wort.
Brewing
Partial-boil is usually thought of as a 'beginners' technique -- and, unfortunately, many people equate 'beginner' with 'bad'. In my experience, partial boil is neither. Yes it's a technique that most first-time brewers use (and that many continue to use), but it can actually be quite technically tricky. For it to work well, you have to be very familiar with your system. You have to be able to measure volume accurately, both the amount of water you add to the kettle and the make-up water. You have to know your system's evaporation rate, otherwise you might be adding more or less make-up water. For the same reason you need to know how much trub to expect.
I don't do partial-boil frequently enough to have all of the techniques down, so my brew day was not silky smooth. One of my fermenters is about 25% full of trub, for example. But I'll be doing more batches this size in the future, so I'm sure that I'll work out the kinks.
A new technique I tried with this batch is the hop stand -- also sometimes called a whirlpool hop addition, or a hot whirlpool addition. The idea is simple, at the end of the boil add your flameout hop addition, stir the wort, cover the kettle and wait. If you want a really strong hop aroma the hop stand can last up to 80 minutes. For this beer I only let the hops stand for 20 minutes.
