Subject: low-gravity malt bill query
|
Hello All
I'm working up the malt bill for my first pale mild at a
target gravity of 1.032. The bill I'd like to try is:
6.5 lbs 2-row
10 oz med. crystal
At 1.25 qts/lb that comes out to about 9 quarts for the
mash. Will I be able to draw 6.5 gallons of wort from such
a small malt bill? I get the feeling I'll have to over-sparge
and then be in danger of flushing tannins into the wort.
Any suggestions? I don't think I have the room in my 5 gallon
cooler to double the recipe, even if I buy another 6.5 gallon
fermenter for primary.
Any suggestions welcome.
Thanks - JB

If you batch sparge it shouldn't be a problem. I think what Dan said
applies to fly sparging.

I do batch sparge, but I'll be sure watch my runoff gravity
just to be safe.
Thanks for the replies!

IMO this is a bit of a misconception. It is certainly possible to
oversparge with batch sparging as well. It's not likely in either case,
fly or batch sparging, but becomes more of a concern with lower OG beers.

I don't see any problems with your grain bill. You should sparge until the
runnings fall to 1.000 UNCORRECTED, then cut off and make up any necessary
differences in the kettle with water. Most likely this will be unnecessary
as I have found that, for five gallon batches, I usually need five gallons
of sparge water. I get the five gallons plus the wort in the tun for boil
loss. Don't worry about it.

Yeah, oversparging is more of a concern with low OG beers. IMO, the best
thing to do is to monitor the runoff and stop the sparge when you get
below 1.010. Then top up the rest of your volume with water. As long as
you hit a decent efficiency (should be easier with a low OG beer), then
you'll have enough sugars from the grain to reach your target.
If you want to get really fancy you can sparge until you hit 1.010 in your
runoff, stop the sparge and measure your current SG and volume. Then
calculate how much water you can add so that your SG ends up at 1.032.

Yeah I think that's what I'll do. I'll watch the runoff gravity
then do some calculations. If I'm a wee bit under I can always
add a little DME. My efficiency has stayed steady between
67%-70% so we'll see how it goes (I always plan my malt bill at
67%).

Indeed. I build my recipes using 67% efficiency as a reference. This
time (due to the smaller amount of grist to sparge I bet) my
efficiency hit 78%! Instead of brewing a 1.032 pale mild I brewed a
1.037 pale mild.
Oh well, live and learn. I'll know to scale back on the grist a bit
next time. Also, I stopped the sparge at 5.5 gallons and then topped
of the kettle with a gallon of water. Seems to have worked fine.
