[so did i extract enough fluid from the canned pumpkin to subtract from the grain absorption?/QUOTE]
That or you made an error in the initial measurement. Don't forget, there will be a great deal of trub. You might want to set your target volume higher.
dave you were right, my initial measurement was off. So when I added extra boil time I ended up with much less than my target of 5.5 gallons.
I added purified tap water to top off as much as I had in the fridge ad got to ~ 5gallons.
Not a pumpkin thing but i think my measuring stick is off.
