On my last AG batch, Northern Brewer's Dead Ringer, we lost more wort volume than I originally calculated due to a split boil.

The target gravity was 1.064 @ 5 Gallons and we ended up at 1.074 @ 4.2 Gallons.

-Would it have been advisable to have collected extra sparge water and kept on the side, to top off to 5 gallons?

-If I did collect the extra sparge water and kept it on the side for 1 hour during the boil, would it need to be boiled to sanitize?

I think you'd be better off adding plain water than more sparge water. Even if you control temp and pH, there comes a point where more sparge == more nasty.

There will also be the issue of proteins in the sparge water that wont be removed (as hot break) even if you boil it to sterilise (without a longer boil).

The amount of protein would probably be a lot lower than the main wort but could be significant - anyone know?

It might have been worth collecting some sparge water that you could add to the boil(s) earlier on if it starts to look like you might get too much boil off.

So did you have more boil off than expected? If this is the case I'd top up with plain water as you would more likely hit you OG target than adding extrat wort. Would seem about right too - 74 *4.2 / 5 = 62

I can only put 27 litres in my 33l kettle pre boil. So i put the excess wort from the sparge in a pot and boil it on my stove. When the main kettle start it's boil, I add the additional wort in my kettle and now can bring the boil volume very close to 33l.

Thanks to all for all of the replies. To answer the above, I ended up with more boil off than expected. My initial question was for future batches in case this happens again.

I'm now also wondering if I collect extra sparge water to put aside until after the boil and I don't boil that extra sparge water for an hour, but use it to top off in my fermenter if I will get DMS in my brew?

Based on the above with my future batches I'm leaning towards topping off with a little spring water if my gravity is high enough.

Is your pot large enought to add all the " extra" wort at the beginning of the boil? If you have excess wort at the end of the boil you can always can it and use it for future starters.

My main pot is a 30Q Turkey Fryer pot and my second pot is a 20Q stock pot. I use these two for my split boil. I also have a 16Q stainless steel pot which I planned to use to collect my extra sparge.

However I'm having second thoughts on if its worth collecting extra sparge water based on the replies I've gotten so far.

I have had to turn my flame down real low during the boil so I don't have as much boil off.
