All the hop matter was floating on the top of the beer when I started - i left the room for about 2 mins and came back and it had all disappeared, apparently sinking to the bottom. No idea why!
UPDATE
This actually turned out OK once it had been bottled despite the somewhat slapdash initial re-rack. A nudge on the bitter side but I think that is by recipe design rather than any process issues. Nothing I could pick up that suggested any kind of oxidation although it's fair to say my palate is somewhat simplistic so may have missed the odd nuance. But that's a good thing right?
