Kettle Loss - Blichmann Hop Blocker
« on: April 29, 2013, 07:19:58 AM »
I measured the losses from my two brews this weekend (12 gal of dopplebock and 12gal of black IPA), using a Blichmann Hop Blocker.  on the first, dopple, I lost just under half gallon.  on the IPA, the hop sludge seemed to 'strand' a bunch of wort, and i wound up loosing about .75 - 7/8 of a gallon of wort. 

Bear in mind this is the liquid that is separate from the hop sludge - not much to speak of on the doppel and a whole fat disk in the center of the kettle on the ipa.

I shop vac'ed the actual available liquid to do the measurements.

does this seem excessive?  i guess as long as I get two full kegs who cares, right?  just wondering if I shouldn't try something like this instead; http://www.stainlessbrewing.com/180-Degree-Tube-Bend_p_103.html

That doesn't seem like a huge amount to me, maybe 5-7% loss in the kettle.  You can try to get that down if you want, but I wouldn't bother unless I had nothing else to worry about :)

I'm not sure what the point of that u-bend is or how you would use it.

Seems about right.

I'm not sure how this measures up to a whirlpool technique, but it's probably not as efficient. Although, as Tom indicated, it's not so bad that I would try to minimize it. Instead, I would focus my efforts on a more qualitative measure to improve my beer. Now if I were in production, it would be a different story, but for homebrewing it seems adequate.

the ubend would be used to suck wort from the very sidewall of the kettle after a good whirlpool.

i whirlpooled pretty good on the black ipa, but probably did not give enough settling time after turning off the pump for recirculation.

Oh, I get it now.  Do you have a tube that sticks into the kettle?  Mine is basically an opening in the side.
