Low gravity, due to boil not vigorous enough

[jmb7504]

I have a 8G tall boy kettle to use for AG batches. I did an IPA recipe that was supposed to have about 7g of pre wort prior to boil. I had more and couldn't have a full boil without it spilling out, so it was more like a simmer. For my next batch can I boil my leftover wort separately? any other ideas comments are appreciated.

Boil longer

Boil longer

Good god, did you even read the post?
My guess is, you did not bother.

OP: Yes, you can boil the overflow of runnings separately. You can either do that and combine, or you can do a partigyle. If you have an 8g kettle, then I think for a 5 gallon batch, you would need at east 7 g pre-boil volume. what's your specific gravity when you reach 7 g? You may find you're at your target SG and you don't need the extra runnings. OR you can do that partigyle thing.


Either way, you should aim to get your full boil in your kettle and keep a rolling boil.

Perhaps less strike and/or sparge water is a better idea. Sounds like your volume calculations need some adjustment.

Hitting your planned preboil volume with no excess will allow you to do your boil in 1 pot.

Excess volume will reduce your OG all else being equal

Agreed! I have an 8 gal pot and do AG...i boil on my stovetop with two burners going...to get my desired 5.5 gal I only need 6.2 gallons of preboil wort! Fine tune your system and you'll be fine!

Cheers!

I use 1.25 quarts/pound and the same for sparge. Never too full.
Sometimes I have to add some water at the end. Not a problem.

Read it, he got it to a simmer, which will start evaporation. Going longer will evaporate more.

Never said he couldn't split the batch, just that there is another way to go about it (which he asked for).

Like just about everything homebrewing, there's more than one way to go about...

Thanks everyone. I was using http://www.brew365.com/mash_sparge_water_calculator.php to give me the info on what my sparge and mash water amounts should be, and got the 7g from that. my target OG was 1.050 and i got 1.040 if that helps fill in details..
