NorCal Brewing Solutions Extreme Whirl Pool / Aeration Beer Brewing Paddle 304 Stainless Steel – 22” Long, 5” Blades Built-in 3/8” Hex Bit. Works with all 1/2" drills and MOST 3/8” drills (see note at bottom) Permanently welded tip. Shaft is completely sealed top and bottom. CHARACTERISTICS and SPECIFICATIONS: · Makes a perfect whirl pool in the boil kettle to “cone” the trub, hops, away from the exit port · Use with a power drill at higher speed settings to aerate wort (after cooling) for enhanced yeast activity · Perfect length to reach deep into large kettles or converted beer kegs, yet short enough to use with fermenting buckets, stove-top kettles · Much better than plastic spoons or paddles – WON’T BEND or WARP when exposed to heat! · Drill end: Features welded 3/8” hex bit so you can optionally attach to a power drill for the ultimate in easy whirl pooling · Blade end: · 3/32” holes on 5/32” centers – Made from the same material as our famous NorCal Brewing Solutions False Bottoms · Allows the perfect amount of liquids and solids to pass through the blades to create a strong whirl pool · Creates a strong, whip-like aeration in cooled wort when used with a power drill. Yeast LOVE the extra oxygen this infuses! · Features a permanently welded tip so mash, trub, or wort doesn’t enter the paddle tube · Quality construction – Made in USA. NOTE: Our 3/8” stainless hex bit measures EXACTLY 3/8”. MOST, but not ALL 3/8” drills will accept this bit. Some 3/8” drill brands are just shy of actually opening a full 3/8”. To play it safe, we recommend that you have a 1/2” drill on hand.
