Read my website…www.dennybrew.com. its kinda hard to give you an exact amount since it will depend on recipe. In a nutshell, mash with whatever ratio you want. Runoff the mash. Measure how much wort you collect. Subtract that from the amount you want to boil. The result is how much sparge water to use. Do that a couple times and you’ll know what to expect. If you have questions, you can always shoot me an email at denny@experimentalbrew.com
Thanks I appreciate it. I’ve used your website as a resource countless times over my home brewing years, obviously just never looked at the sparge section before.
When i did went to all grain. Took me a while. Get my numbers dialed in. But now. I do 7 gal boil batches. To end up with 5.5 gallons. My vourlauf slow. About 34 min. Most the time end up with a preboil grav of. Between. 1 050 to 1.044. Me do stop sparging when i got 7 gal wort. Indeed they say. Stop sparging. When you reach. 1.007. Or when you reach your target volume.
Chugger pumps are magnetically driven and perfectly fine being throttled with a ball valve on the output side. Literally everyone does it and it’s advised on their website.
No I’m aware of that, I have no issue with that. I used to do it, but took it off. That’s not what we were talking about. A VFD is a variable frequency drive, which basically just changes the frequency of the electricity that reaches the pump. The lower the frequency, the slower motors run. However, you need motors that can actually handle these changes, otherwise you will burn out the motor quickly. I don’t believe a chugger is designed for variable frequency.
Gotcha. I misunderstood your post re that. No clue and don’t see why it would be necessary since a ball valve works fine.
Yea it’s just more of an automated thing, since my system is all automated it could keep that standard going. I have no problem with using a manual ball valve… for now at least, in the future I may get an automated one and just wire it for any possible opening rather than full open / full close. Much cheaper and easier than a VFD, and takes up much less space.
