THe are usually 6 gallons finished, 5.5 gallons into the fermenter and 5 gallons kegged or bottled.

So just to clear my confusion, when you do all grain brewing, the amount of wort after you mash and sparge should be 6 gallons, then .5 gallons is lost during the boil, so 5.5 gallons go into the fermenter, and finally another .5 gallons is lost to evaporation while in the fermenter, which yields 5 gallons in the bottles?

Around 7.5 gallons goes into the kettle prior to boiling, 6.5 is left after boiling but still hot, 6 is what is there after the liquid contracts in size from cooling, and you leave about .5 gallons of sludge in the kettle, when you put the cooled wort into the fermentor, which gives you 5.5 gallons in the bucket/carboy. After you ferment you lose about .25 gallon to CO2 into the air, and about a .25 gallon left in the fermentor as trub/yeast sludge. This leaves about 5 gallons to go into the keg or bottles.keep asking all the questions you want

FLy sparging is when you are draining your mashtun, you continuously add water to the top of the tun to replace the wort being drained out of the bottom. Batch sparging is you just drain the mashtun til dry, add more water, stir like crazy and run dry again. Both have their champions, but both make great beer.

Since I've always fly sparged, this brings up a question for me. Do you just throw ~180 degree water back into the second batch for draining?

People seem to indicate they get less stuck mashes from batch sparging? I have a single bazooka screen in my tun back home. Is this the case? And, don't you have to bump up your malt bill a tad to compensate for less efficiency doing batch sparge?I'm asking because I want to try it. I never had a sparge arm, I just kept an eye on the volume in the tun, and added more water with a ss pot to top it up.

my efficiency never suffered switching to batching, my cooler and stainless hosebraid has had 1 stuck sparge in dozens of batches, my old false bottom stuck at least 6 times, then it warped

So you don't let it rest at all? For whatever reason when I started doing all-grain (years ago) I must have read to let it sit for 15min and have been doing it ever since. Heck I don't even stir it. Just pour 180 water let sit for 15 min, vorlauf then drain. I wonder what kind of difference it makes? I

When I batch sparged, I would stir and let the grain sit for 10 minutes so that the sugars could get saturated into the water. Then I would vorlauf and drain. I usually split it into two batches. So to do a batch sparge would take me 20 to 30 minutes post mashing.

Question, HD didn't have any SS 3/4 washers. I got two zink coated 3/4 washers. Could I use the Zink one inside the MT or do I need to find a SS one?Dan

Zinc will eventually rust and will need to be replaced with SS. You can use them for the short run but get some SS washers as soon as you can.

Well, my sparge water is more like 190+, but yeah, you're basically correct. See www.dennybrew.com
