Hot break material off tastes. Should I whirlpool?

[manticle]

Balance is key but by the time I let convection currents settle and whirlpool, my wort is getting below isomerisation temp.
Reduce the bittering charge if need be (by experience rather than hypothesis) but I'd prefer slightly higher ibu than tannins or hot break off flavours. Your brew - try stuff out, find where you sit and brew accordingly. At the moment, it seems yours is nor working as well as you would like.

Are you using glad wrap or a lid + airlock? I found when glad wrapping for 2+ weeks, my beers developed prominent acetaldehyde. Fine for short ferments, but at 3-4 weeks like yours I would use an airtight seal
