All Grain Brewing / Re: Simple Grist American Barleywine

My (ahem) award winning BW uses a healthy does of C60 and Munich along with the pale malt.  I think wheat might thin it a bit, which might not be bad if that's what you want.

Higher temperature sparge water dissolves more tannins and presumably more silicates.  Tannins cause chill haze.  Anyway I may be over obsessing on one experiment.

Yeah, you may be!  :)  FWIW, I use 195ish sparge water and don't have those issues.  It may be more theoretical than actual.

I was wondering if the sparge water temp could relate to the lack of clarity of the sparged batch although pH of sparge was controlled. Anyway,  I didn't see the sparge temp reported.

In what way would the sparge temp have affected clarity?

What was the temp of the sparge?

Doesn't matter.  Hotter sparge water does not extract more sugar.

My question relates to the reduced clarity of the batch sparge beer not to efficiency.  I've been cold sparging for no-boil beers for some time ....

Sorry I misunderstood.  What's your thinking there?

What was the temp of the sparge?

Doesn't matter.  Hotter sparge water does not extract more sugar.


The sparge volume (8.75 gal) being much larger than the mash volume (3.75) is non-optimal efficiency wise.

Doesn't matter a whole lot.

I find the only 2 point gravity difference between batch and no sparge to be interesting. I expected a bigger difference in efficiency.

I too am intrigued by this.  Should be at least a 10% efficiency swing in my experience if not way more.  Otherwise I have to wonder if they did it right!  Brings the whole thing into question.

That said, I am not at all surprised that tasters could reliably detect some difference, given the benefit of the doubt that the no sparge truly was not sparged etc.

Dave, Dave, Dave.....these results, whether from Brulosophy or Experimental Brewing, should ALWAYS be in question!  All we can do is orovide some data points based on our investigation to point you in a direction to find out for yourself.  No one should take any of these as absolute gospel.

The difference in clarity is evedent in the post fermentation, pre gelatin pictures. My first thought was chill haze or a varible with the gelatin process. But perhaps it is a yeast performance issue?

It could be a number of things, which is why it's kind of a meaningless indicator with only a single test.

This is exactly what Budweisser does. That said, theoretically you may be breaking colloidal bonds and affecting mouth feel and body.

I did it for years before I got a bigger kettle and had no problems.

The author acidified the sparge water by quite a bit. I wonder if that has anything to do with the haze.

Another possible cause could be the second stirring required. I love press pot coffee and the key to a good clean press is to only swirl in the beginning and NEVER stir before the press. Maybe something similar is happening here.

I doubt it's the stirring.  For that matter, I doubt it's the batch sparge.  Too may people make crystal clear batch sparged beers for that to be the difference.

I know, it isn't a rational feeling. Though I do fit squarely in your "oldschool master" mindset, so that's likely a factor.

Maybe I just need to see it sitting on the shelf at the LHBS, then I'll go out and try it...

FYI, the guy who turned me on to it is profiled in the book as an old school master, so there!  :)  And you won't find it at your LHBS, at least for a while.

Please keep in mind that it's only a single data point.  The key to validity in citizen science is repetition.  Don't take this, or most any experiment done by Brulosophy or Experimental Brewing, as the final word. For instance, the difference in clarity could be from a number of things.  A single trial is only the starting point, not the end.  Try it yourself and see what you find.

Mostly agree with British styles as I open ferment my bitters and milds and tend to abuse the yeast a bit more than other strains. Except, I made my most recent dark mild with Brewtan B and at one week in the bottle it's better than any mild I've made previously using the same recipe, whether it's aged or not. Still waiting to hear back on someone who's used it on a hoppier style. Regardless, I'm starting to believe that there is something to this stuff for home brewers. The purported stability effects might be more important for bottlers. Hard to say without more data.  :D

Sorry to derail the thread a bit here...

Thread derails are how we all learn around here!

That being said, I won't derail further. But as for Brewtan B, I'm torn. I'm really interested in it's affects and the results folks are getting...but at the same time I'm having a hard time "liking" adding a "chemical" to my beer. Yes, I know it's irrational, there's nothing wrong with Brewtan B at all...but there's a part of me that's bothered by it. That being said, I do use whirfloc, isinglass, gelatin, etc. I don't get it.

EVERYTHING is chemicals

Tinseth here.

More line. Beer is moving too fast.

If the beer is moving too fast, couldn't I lower the psi on the regulator to slow it down?  Or is the only solution to add more line?  If so, how much line?

The idea is that you want the resistance of the line to match the pressure you're serving at so the beer comes out of the tap with just above zero pressure.  If you reduce the psi on the regulator the beer will lose carbonation.
