Where do I add Pumpkin in Biabacus ?

Post #1 made 11 years ago
by dom
I've got a Pumpkin recipe attached which calls for 700g pumpkin. I've added it in miscellaneous but I think it might need to go into Section Y. This is because I want Biabacus to try and figure out my correct Mash volume as I imagine it will be affected by the pumpkin going into the mash.
Whats the best approach for this ? I am unsure of the figures to put in section Y as I think not much sugar will be extracted - but as I say I expect my water volumes to be affected by it.

Cheers

mmm....

I was originally going to say; don't enter it at all. There should be little contribution other than volume, and the 700g will displace approx. 700ml so as long as you are not near your kettle limits you should be OK to "ignore" it...

However, I have just looked at a recipe I have that I meant to do last year (but never did), and this called up 1.2Kg of pumpkin, but I had 60 FGDB & 80% MC (5.5ppg) :shock:

I have no idea how or why that is there but... :scratch:
Sorry, it doesn't help you but I have no idea whether to add it or ignore it now. :sneak:

dom, when you say it "calls for", is that in the mash or the fermentor? It's probably a stupid question but I know nothing about Pumpkin Ale. Something though is making me think it is added in the fermentor???

Dom, In America it is mostly added the Last 10-25 minutes before end of Boil, since the Pumpkin need to gelatinize(Cook).

At this Link https://byo.com/stories/item/324-brewin ... m-the-pros

They Hint to "Cereal Mash" the Pumpkin and add to the Mash, so it may need Conversion.

Yeah the recipe says to add the pumpkin to the mash. Its a mash temp of 62 as well which I thought seemed a bit low but there you go. It's from the byo magazine pumpkin issue a couple of issues ago. The Weyerbach one.

Dom, yes, the 62C is low for Barley mashing.

That is where the Step-Mash process comes from. Mash the Pumpkin at 62C for 20 minutes, raise the Temperature of the Mash water to where you need for Infusion and Mash it ALL.

OR take 1/3 of you TWN, Raise the temperature to boiling, add the Pumpkin, raise the Temperature to boiling, Turn off the heat, wait for 10 Minutes.
Dump this Hot Pumpkin mash into your Bag and the remaining TWN, heat to infusion temperature, and BREW!

This Process is called "Cereal Mashing" and Works well for Rice, Corn, Potato, Sweet Potato, Amaranth, Quinoa, and Teff, too.

Oh OK. So I only mash the pumpkin first @62 then raise temp to say 68 and dough in?
I will first of all be baking the pumpkin and then I will mash it with a potato masher before adding to the brew mash.

Cheers, appreciate your help.

Dom, the Pre-Cooked "Oven Made Pumpkin" (With Pie Spices,Yum) can be added directly to the TWN, then raised to Infusion Temperature.

Dumping the Mashed pumpkin into the Cold TWN will help heat the water, too!

Dom,

Correct the Pumpkin is Fully cooked(gelatinized), and ready for Conversion by the Barley/Wheat.

Adding Hot Pumpkin to the mash water, saves Energy.

Oh nice one Mally I missed that when I searched. Ok I think I will steep whilst heating to strike temp, remove pumpkin and top up water if needed to get the correct TWN.

Cheers
