Whirlpooling hops is good practice before you pump the wort out of your brewing system.
It infuses the wort with the hops through using whirlpool movement.
This also promotes enhanced yeast activity and places the hops and protein back into suspension before the filtering process. 

The Grainfather Whirlpool and Aeration Brewing Paddle provides an excellent whirlpool by allowing the perfect amount of liquids and solids to pass through its large blades.
Just simply attach to a standard electric power drill via its ‘chuck bit’ styled end for aeration or hop infusion of your wort. 

Airation of wort is best done under 20 deg C. We don't recommend aerating hot wort.
