Sparging 45 min vs 30 = BE% gain?
 
Howdy,

My efficiency has been around 65-68% so I have decided to sparge for 45 min instead of the usual 20-30 min. I'm in the middle of the sparge right now and I was wondering if I can expect some gain on my brew house efficiency? If so how much do you think?

If you're batch sparging, I wouldn't think you'd get any better efficiency, but of course I could be wrong about that.
If you're fly sparging, you could get a few percent extra, and if you extended it to 60 - 90 minutes, you could get yet another few percent. However, long sparges with low gravity do tend to oversparge. (I'm talking about 90 minute fly sparges to get a gravity < 1.040 into the kettle.)

-a.

Edit - Changed 1.050 to 1.040 (typo)

If you're trying to save time sparging and you're not happy with less than 70%, go for batch sparging.

Ya i do the good old fly sparge but ill have to give the batch sparge a go. Let ya know how this one turns out although I did change my crush also. We will see how the % BE turns out in about 1 hour :)

+1, I tried the whole fly sparging thing to no avail, but batch sparging is just plain easy! I tend to get about 70-75% efficiency..

Wait, what is your recipe, or in other words, how much grain are we talking here? Slower, controlled sparges will get better yields, but there can be a cost. I think the main thing is to settle into a set routine a STAY there. I think if you hit the 70s you can be happy and secure. These 95% yields scare me, I worry about all the EXTRAS iI am pulling along...

I am a fly guy and I like it. Gives me more time to drink!

Good thread. Anxious to see more replies.


.....Let me Explain. I just recently jumped from 62% Efficiency up to 78%, in one Brew Session. The different parameters were that I used a PH Balancer(With House water through a filter instead of Poland Spring), I used my new JSP AA Malt Mill(Been using my buddy's, who has been getting 83% from his), AND I SLOWED down my Batch sparge to about 1 quart every 4 minutes. I am anxious to brew this weekend as many here say that a slower batch sparge doesn't do anything to your Efficiancy numbers. Well, we'll find out this weekend as I wil do the same, take more meticulous Notes, and brew the same Batch the following weekend but I will let the Batch Sparge rip versus 1 quart every 4 minutes.

I really enjoy fly sparging and if you are going to fly sparge then you need to "slip it on as you slip it out"* I am so used to bigger batches and so longer times that I can not remember the targets of ounces per minute anymore. I will look it up and let you know.
