Loving this idea Rob thanks for the link.
I usually regard hops just a a counter balance to the sweetness of the malt as I prefer malt forward beer. But I'm just about to start doing lots of 5L brews instead of just one 23L at a time. One of the reasons is so I can start experimenting with hop flavours and getting to know what they tastle like - an area sorely lacking in my brewing knowledge.
I was just going to make a series of lots of 5L SMaSH's but with this link it has given me the idea to do the following:
Make a 5L SMaSH, low ABV% about 3.5% and only bitter hop it to about 22IBU. Then follow the instructions in the link to open up a bottle after it's fermented and drop in some hops.
That way I don't have to buy beer - I never buy beer from the supermarket as I can make it so much more cheaply and tastes nicer. Plus I wont have to put on a disguise
Edit: Also it means I can try lots of different hops with one 5L brew as I get about 12 or so 330ml bottles out of each
