Pumpkin Ale Preliminary Brewing Steps
- Bake 3 15-oz cans pumpkin at 350F for 45 minutes.
- Place brew bag in pot.
- Add 2 gallons water to pot and heat to approximately 160F.
Note: 2 quarts/lb. of grain, as per John Palmer’s “How to Brew,” 3rd Edition, Page 151. Should I add more for the 45 oz. pumpkin puree?
- Add pumpkin, 3 lbs Rahr 6-row, .5 lbs Briess Caramel 40 (from “Smashing Pumpkin Ale” kit) and ½ cup rice hulls to brew bag.
Note: is ½ cup rice hulls enough?
- Hold at approximately 152F for one hour.
- Remove bag from pot, place in strainer, and drain into pot.
- Sparge bag in 1 gallon clean ? degrees water for ? minutes.
- Sparge bag again in 1 gallon of ? degrees water for ? minutes.
- Combine wort from initial boil and both sparges.
- Pour wort through grain heap into brew pot, to filter the wort, and continue with brew instructions, adding LME, hops, and spices as directed.
A few comments (marked with ==>) and rearranging the order somewhat:
1. Bake 3 15-oz cans pumpkin at 350F for 45 minutes.
==> Spread out onto one or more baking sheets. The larger the total surface (the thinner the layers) the quicker it evaporates. There's a lot of evaporation in the beginning, if you have a convection oven it may speed things up. It may help to leave the door slightly ajar to help with evaporation until most of it has evaporated. It won't brown much until most of the water is gone.
==> It may take more than 45 minutes, time is not that relevant, it's the browning you're after.
Once the tops start to brown, scoop them over (using a flip or so), and keep doing that until the pulp is nice and toasty looking medium to darkish brown.
Careful not to burn it!
2. (was 3) Add 2 gallons water to pot and heat to approximately 160F.
Note: 2 quarts/lb. of grain, as per John Palmer’s “How to Brew,” 3rd Edition, Page 151.
Should I add more for the 45 oz. pumpkin puree?
==> That volume should be fine, a good start. 1.5 - 2 qts/pound of grist is very nominal. If the puree soaks up more than expected, you could always add more (hot) water if it's too thick to stir. "Steal" the water from your sparge water reserve so your total water used doesn't change.
==> Use a mash water calculator to estimate the needed temperature of your strike water. Most ideal is when you hit your mash temp spot on after adding your (milled) grain and adjuncts.
==> If you undershoot the mash temp, you can slowly heat the mash pot, on lowish/medium heat under constant stirring and scraping the bottom, so nothing sticks to the bottom and scorches. Do that, while monitoring the rise in temp.
3. Place brew bag in pot.
4. Add pumpkin, 3 lbs Rahr 6-row, .5 lbs Briess Caramel 40 (from “Smashing Pumpkin Ale” kit) and ½ cup rice hulls to brew bag.
Note: is ½ cup rice hulls enough?
==> All the grain is milled, right? But don't mill the rice hulls!
==> As was already pointed out, start with
1 cup. That should be OK, add more later, if needed. But the bag itself is also a filter, much more forgiving.
5. Hold at approximately 152F for one hour.
==> What kind of pot are you mashing in? How large?
==> Put a lid on it.
==> If possible, put the lidded pot in a prewarmed but
turned off oven at 155-160F (check it!). Much easier to keep that 152F mash temp in there. Starting the oven a little higher than your intended mash temp is usually recommended, it will cool down from there, such as opening the door. You could/should double-check your mash temp (in the pot) 10-15 minutes in. If a bit too high (>156F), you could add a little cold water, stir and put back in there. But usually it's just OK to let it be. Don't try to raise the temp.
==> If not in the oven, wrap a thick blanket, or a few thick towels, etc. around it to keep the heat in. Insulate the bottom and lid too.
6. Remove bag from pot, place in strainer, and drain into pot.
==> Then pour the collected wort through grain heap to filter it (those are your first runnings).
==> Remember,
each of the runnings need to be filtered like that, by themselves. IOW the filtering needs to be done at each step, after draining the first runnings, and after each sparge.
==> Put your now filtered, first runnings in the boil kettle, or some other
holding vessel (bucket?) if you need your kettle to collect the wort from sparging (in 7. and 8.).
7. Sparge bag in 1 gallon clean
? degrees water for
? minutes.
==> Just dunking and lifting (up and down) a few times is fine. But if the bag is compacted, stir it a bit too. One minute (or 2) is good.
==> any temp
under 170F is fine. Either cool, cold, lukewarm, or up to 170F water is fine. Warmer water may help to keep it a bit thinner, more fluid, but it's not essential. This is batch sparging, easy peasy.
==> strain into a vessel,
but not into the one you're storing your first runnings in. The wort from the sparge needs to be collected separately, then filtered, first.
==> Filter as in step 6.
==> add collected (now filtered) 2nd runnings to your holding vessel that already contains your first runnings.
8. Sparge bag again in 1 gallon of
? degrees water for
? minutes.
==> Repeat as in 7.
==> You're now collecting, then filtering, your
3rd runnings, again by themselves, before adding to your holding vessel.
9. Combine wort from initial boil and both sparges.
==> Obsolete. All your wort (all 3 runnings, each collected and filtered individually) should already be in your boil kettle or
holding vessel (bucket?).
10.
Pour wort through grain heap into brew pot, to filter the wort, and continue with brew instructions, adding LME, hops, and spices as directed.
==> (Strike-through text above) Do
not pour your wort through your grain filter again, it negates the sparging.
Sorry if that was confusing and not clear from the beginning.
Once you do the process it should all make more sense. You're trying to remove as much as possible of the sugars trapped in that grist (bag). In that process you also clarify it better, fine suspended grain dust and pumpkin pulp mostly, that is being filtered out.
==> Your wort will be hazy, but most will clarify at the end of the boil.
==> If you have some, you could add 1/2 teaspoon of Irish Moss (or a whirlfloc tablet) with 10' left in the boil, to assist in coagulation of the break matter. But only add it if you already have it, no need to special buy or order it. The beer will all clarify once fermentation is done, leaving trub and yeast behind on the bottom of the fermenter.
Do not use a secondary! Leave the beer in the same fermenter until ready to package.
Good luck with your Pumpkin beer brew, it's quite an experience!
