I added (2) 30oz cans of Libbys Easy Pumpkin Pie Mix to my 5 gallon batch of Brewers Best Pumpkin Porter. This is basically puree that has already been spiced with cinnamon/nutmet/ginger/etc...
I dumped both cans into a baking dish, then baked for 1hour @ 350F. After it cooled I dumped it into a large a large strainer bag, and zip tied it shut.
I let it sit in the secondary for a little over a week and a half. Since there are fermentables in the pumpkin, it will start fermenting again. I tasted it 3 nights ago and it tasted great!
I went to bottle it today, and it tastes really bitter. I don't know what happened to change the flavor within 3 days, but I'm now looking for ideas to make it taste good again.
I don't want to dump the whole batch, so I'm thinking of back sweetening with some light Belgian candi syrup, and then pasteurizing it once it gets carb'd up.
Other option I can think of is brewing some Dunkin Donuts Pumpkin Spice coffee, and trying to add it to the beer.
At this point I'm willing to try anything. If anyone else has any experience please chime in.
Also, I think the pumpkin puree may have actually absorbed some of the pumpkin pie spices...idk for sure though.
