cold water enters in longer end, splits. some goes round the top, causing convection to send cooled wort down through the 13" chasm, where the other half of the cold water carries on the good work. useless, warm water exits from the middle of the IC.
we shall see in about 2 hrs how well it works (2nd batch is draining now...)
EDIT:
btw, this monster IC is going to grace the hoppiest beer I've done so far:
24L @ 1.050
who knows what IBU
50g amarillo FWH
150g amarillo last 10 mins
WLP029
Just for the record - that was too much amarillo. don't care if i never taste that hop again!
