Batch sparging, in comparison, only requires a mash tun with a false bottom and ball valve. Once the mash is complete, batch sparging consists of a few easy-to-remember steps. The best prevention for a stuck sparge comes before the sparge begins. There are two main reasons that a sparge becomes stuck. Preventing a stuck sparge starts with the grind of your grain.
My first batch sparging experience was with grain that was ground twice as fine as normal. This is often recommended for brew in a bag setups and I had recently switched over. The result was a sticky, gluey mess and an almost unfixable stuck sparge. For batch sparging, be sure to grind the grain just enough to break the kernels, not enough to crush them.
No matter how roughly you mill your grain though, it will still include some powder. This is where the temperature of the sparge comes in. Cold or room temperature sparge water may cause the powder to lock up. It will then lock any sparge water from moving through the grain bed and cause a stuck mash. The solution to this is ensuring all sparge water is heated to about degrees. The final preventative step you can take is to add rice hulls to your grain bill.
These add no flavor to the beer but create airspace for the sparge to travel through. You followed all the steps above, but your wort is still coming out in a trickle or not coming out at all. The first step is to close your ball valve and stir the mash bed aggressively. Focus a lot of your efforts near the bottom of the tun, where the problem is worst. In other words, blow into the tubing leading from your ball valve.
As this is pre-boil, any sanitation issues will boil off. If any grain goop makes its way inside the valve, this will be the most efficient way to dislodge it.
Batch sparging is the perfect sweet spot between using a bag or even malt extract and a full fly sparge setup. It is inexpensive and easy to set up, making it a favorite among homebrewers. With the tools and skills outlined above, you have everything you need to be a batch sparger! Still have questions? Batch sparging sits somewhere between brew in a bag and fly sparging for the most efficiency.
This can move up or down based on a variety of factors such as individual processes, the crush of the grain, etc. Mashing out is raising the temperature of the mash to around degrees before sparging. Usually, you do this by adding boiling water to the mash tun. For fly sparging, this is necessary to stop the enzymatic action of the grain.
In other words, you stop the grain from turning all the body of your beer into fermentable sugars. For batch sparging, you create the mash out during your first batch addition.
When you add a large volume of hot water to the mash all at once it keeps the heat enough to stop the enzymes. It also thins out the wort to make sparging easier. You do not need one in batch sparging. Batch sparging is a bit slower than an extract or brew in a bag process. This is because it needs running water through the grain bed rather than lifting the grain out of the wort. Slip another hose clamp over the end of the long piece of tubing, connect the tubing to the output side of the valve, and secure with the hose clamp.
This is from a 8-gallon 30 L batch of altbier I brewed recently. Remember that the method can be used with any brewing system or equipment. The things that you need to know to figure your water volumes are: Total grain weight, in this case, By knowing how much water you put in and how much wort you got out, you can easily figure your absorption.
Finally, we need to know our pre-boil volume — how much sweet wort you need to start with. For this batch, we want 10 gallons 38 L , which on my system will yield 8 gallons 30 L of post-boil wort.
Mash in with 6 gallons 23 L of water for 1. I use the pitcher to pour water from the 7 gallon 26 L kettle until the kettle is light enough to lift and pour the rest of the water in.
I predict that the grain will absorb 1. After 10 more minutes, I begin to recirculate the mash by draining into the pitcher.
I only open the valve partially at first, then as the runoff clears I open it up fully. Keep draining and recirculating until the runnings are clear and free from pieces of grain. Once the runnings clear, direct the runoff to your kettle, and slowly pour the contents of the pitcher back over the top of your mash. Completely drain the mash tun as fast as your system will allow. As the first runoff progresses, start heating your batch sparge water.
When the first runoff is done, add your second addition of sparge water. Stir the grain thoroughly, close the cooler, and let it rest for a few minutes. After the rest, open the cooler and thoroughly stir the grain once again. Yep, you read that right! We want to get all the sugar into solution. Go through the recirculation and draining process again, once more draining the cooler as fast as your system will allow. Continue the brewing process as you usually do.
Like anything else in brewing, it may take a couple tries before you get everything figured out completely. But with batch sparging, you can brew all grain beers with a minimal investment in equipment and a pride in the hands-on fun of homebrewing. Decoction mashing has both a mystic and feared quality to it.
Purists imagine achieving perfection in the ultimate Bavarian or Bohemian lager. The more pragmatic of us fear the time-intensive triple decoction.

Fly Sparging Most brewers practice continuous sparging. Batch Sparging Batch sparging is similar to partigyle brewing. Formula It is relatively simple to figure out how much water to add for each batch. We did a double mash on it i. If you tried to do a continuous sparge it would only last about 5 minutes so we just started doing it that way to minimize the chance of getting low gravity last runnings from sparging too much. I've never actually batch sparged before professionally or homebrewing but that's probably the closest thing to it.
It worked great, and I wasn't all that concerned about efficiency as the last runnings were about 17 degrees plato usually what a waste! I never really understood why people like batch sparging in homebrewing, but I definitely wouldn't do it professionally.
You would wind up having to put in extra pounds per mash on a 15 bbl system to save 45 minutes. I don't know of any brewers who are paid well enough to make that make sense.
It was also plato. Checking the last runnings always made me cringe. What the heck is batch sparging? Never heard of it and I'm quite curious. Plattsburgh, NY. Batching is just faster and it cost me nothing extra to do it. I'm careful to monitor the grain bed while sparging. Just a few centimeters above the grain with sparge water. Much more and you hydraulically smash the bed. Much less and you crush it with gravity.
I imagine that in batch sparging, you'd have to really mix things up and vorlauf again. I can't see the benefits of batch sparging. I get great brewhouse efficiencies with continuous sparging. Have to watch last runnings to make sure I don't go too low. As Joe pointed out, surely there must be diminishing returns on batch sparging for larger batches.
