Taking a poll on what the avg. yield is from a 5 or 5.5 gal boil - I
usually end up with 3.5 - 4 gals at most after bottling.

Re: average yield from 5 gal boil


I do a 6.5 gal boil. after an hour or so it boils down to 5.5 where I
ferment 5.5 gal, then rack 5 gal to a keg.

i.e. I end up with 5 (give or take 0.1 gal) gallons at kegging.

(Do a larger boil...I think there are efficency problems if you are
doing all grain. if not, and you are doing extract are your beers
ending with a high starting gravity?)


Re: average yield from 5 gal boil


For me, a 12 gallon start in a 12.5gal pot ends up between 8.5 and 9 gallons
after 90 min

Re: average yield from 5 gal boil


I start with 6.25 gallons and end up with 5.5 at the end of a 60 minute
boil. My boils aren't that vigorous because I've got  a 7 gallon pot.


Re: average yield from 5 gal boil



My starting volume for my last batch was 6 gal. and I ended up with 4
1/2 gal. and added water to achieve 5 gal.  It took a long time to get
the wort up to a boil.  I didn't want to cover the kettle because I
didn't want to lock in dms.  Will this be burning off before the actual
boil?  Can I leave the kettle covered until the temp. is around 205F?

   You can leave the kettle completely covered until
you achieve a boil.  DMS will be driven off after that
point.  I do that, and continue the boil with the pot
about 80% covered.  I've never had DMS problems with
my beer.
   And to be entirely clear, four things are helpful in
reducing DMS levels in finished beer: a vigorous boil,
a 90-minute or longer boil, limiting stand time after
the boil, and chilling the wort rapidly.

I'm not sure how long DMS would be an issue, but if you have a way to cover
the kettle with a lid that is at an angle so the condensation will drip off
to the side and not back into the wort, DMS should not be a problem.

I have a 15.5 gal keggle that I do my boils in and I have a lid that fits
over the very top of the keg and doesn't cover only the hole I cut in it. I
then prop the lid at an angle by putting a clamp on the side so the
condensation runs down the lid, hits the handle of the keg and drips into
the outer ring of the keg and either evaporates or runs down the side of the
keg and cooks off.

I have never had problems with this method, though I don't know what DMS
tastes like, but no one has ever said "wow, taste the DMS in this thing!"

Re: average yield from 5 gal boil



lucky4fingers, sounds like you need a larger pot to boil the entire
wort. You
get better hop utilization and better beer boiling the entire
volume. Get a 10
gallon (40 quart) pot to do 5 gallon batches. That lets
you start with 6.5 or 7
gallons to end up with 5-5.5 gallons and gives
plenty of room for the vigorous
boil. You then will get 5.5 gallons to
start in your primary which after
racking, will leave you a full 5
gallons of beer in the secondary.

It differes slightly for everyone, but I start my boils at 6.5-6.75
gallons and always end up with around 5.5 gallons in the primary,
which allows for some loss on the way to bottling.

We always end up with 50-52 bottles per batch.

Re: average yield from 5 gal boil


Maybe I should actually measure how much goes in the fermenter after my
next boil. I do a full 70Min boil in a 10 gal pot. Partial boils & boil
overs aren't a problem. Chilled with a home made immersion chiller (I like
to build stuff). in ~ 15min.

Re: average yield from 5 gal boil


Start out with about 5.5 gal. Add ice during the chill process to
replace what was lost during boil and helps chill faster.
7lbs ice approx. 1 gal water.

I suppose your ice is unlike any around here and completely contaminate
free.

Re: average yield from 5 gal boil


I was always concerned about contamination from the ice too. My friend
has been using it for years and never had a problem so I gave it try
and it's work fine so far.

The beer guru at my local homebrew store ALWAYS adds a bag of ice to
the fermenter to help cool the wort, and has never had a problem. I
didn't do it for a long time, then finally tried it, not a problem yet.


Re: average yield from 5 gal boil



Yea, don't add ice.  You lose roughly a gallon in an hour boil.
