Another great video, thanks Bobby! BH yet again responding to needs of Homebrewing community; another reason why we love BH and are loyal, long time customers. I made one of theses from copper pipe to hang over kettle but will be ordering a stainless from you for new Anvil Foundry. Keep up the great work, and thanks again!

I have both the "shorty" and "overboard". Both are great products! The overboard I use to recirculate the mash.

Awesome beard dude! Rock on! I got one of these awesome spin cycle attachments too!

[@freshcutfilmssf633]

I tried to order one. Do you know when you will be back in stock?

[@tinyeehoang3649]

Is there an optimal height from the bottom of the kettle?

[@brewhardware]

We have found it doesn't matter much. We get the same centrifugal movement as long as we keep the outlet more than an inch from the bottom or top of the liquid column.

[@MrMunstermonster]

Does it matter which direction your whirlpool spins?

[@brewhardware]

No, not really.

I like to take my temps down to below 50 when whirlpooling with my version of the overboard, but in this method you have the boiler exposed to the air. I had a wooden lid made up to counter this.
