I just used Whirlfloc for the first time yesterday and, like others who have used it, I was shocked to see the amount of spongy-looking trub in my carboy. It's fermenting like crazy right now so there are chunks floating around everywhere but, before transferring to my carboy, I transferred a little bit of the wort into the Erlenmeyer flask that I did my starter in to take gravity measurements from time to time and every time I pick it up the spongy trub at the bottom immediately starts floating around. It seems to be very buoyant; more so than what I'm used to with normal trub. My concern obviously is that when I am ready to rack this beer for bottling and I pull my carboy up out of my chest freezer it's all going to get mixed around since this trub seems to be really easily shaken up.
Any feedback from you guys who use Whirlfloc? After fermentation will it eventually compact at the bottom of my carboy like always or have you found that this "Whirlfloc trub," as I've dubbed it, is more easily shaken up and extra care needs to be taken when racking? I'll probably set my carboy on my kitchen counter a day in advance just as an insurance policy but this stuff is so easily shaken up (at least right now) that I'm concerned the vacuum created by the siphoning tube might be enough to stir it all up when racking.
