If so, in which direction? I'm adding 58 oz of baked Libby's Pumpkin Pie filling to 12 lbs of grist.

These guys say that adding it to the mash has been unproductive for them, but the posting is a little older, there may be better documentation out there but I thought I'd share.

I see nobody ever answered your question... I have the same question. Does pumpkin affect the mash pH? I know I can take a pH reading while I'm mashing but I would rather be able to guesstimate a bit beforehand... Bueller?... Bueller?... Bueller?

Unless the added material is at the same pH as the mash without it it will effect the pH. The direction depends on whether the pumkin is at higher or lower pH than the mash (it will pull it in that direction) and the magnitude of the shift will depend on the pH of the mash and pumpkin and the buffering capacities of each. Clearly a test is the simplest way to answer this question.

For sure. I guess I was more curious if anyone had already conducted such a test ;-)

Just add the pumpkin near the end of the mash and it won't make any difference. There's no need to mash pumpkin anyway since there's so little starch in it. Check out the can's label if you don't believe me.
