So, now that the two pumpkin comps are done and dusted, anyone willing to detail their experiences of working with pumpkin? It would be equally helpful to hear of the stuff you wouldn't do again or what you would do differently as to hear from the comp grinners.
I'm sure my asking this has nnothing at all to do with me biting the bullet and finally making one myself next brew.
I brewed two beers that had additional spices added, and I personally didn't notice much flavour contribution from the pumpkin underneath the spices.
The first beer was a pumpkin pie sweet stout. I replaced 1kg of base malt from the original recipe with 2kg pumpkin, and still came in 8pts under my pre-boil gravity. Some brewers who tasted that beer thought that the pumpkin may have added to the body of it, but with the lactose in it, it's a pretty full bodied beer to start with. I definitely liked the spiced aspect of this beer and would brew it again, but not necessarily with pumpkin. For the spices, I added 15g of this straight to the keg:
The spices came through quite strong at first (probably from being drawn straight from the bottom), but mellowed and blended over time. I would probably back that off to 10g next time, and add more if I felt it needed it.
The second brew was wheat ale with honey and ginger. I'd brewed this
Australian white xmas ale recipe a few times before with US-05, and thought that the honey & ginger would work well with the pumpkin. For this recipe, I ditched the lemon zest and I replaced the 250g wheat flour with 3kg of pumpkin (and still struggled to make pre-boil gravity). If you really search for it, you could possibly find some pumpkin in the aroma and flavour, but again, the honey & ginger dominate this recipe.
Well I know one of the winners has said to me that they will definitely roast the pumpkin first next time. Peeling 3kg of pumpkin wasn't much fun for them
A lot of people did roast it first, and I would definitely second that from my experience.
Yep, that would be me

. I peeled, boiled and blended the pumpkin for both beers and added the puree to the mash. What's worse was winning the comp and having to do 9kg for the commercial brew
This is what you hand looks like after peeling said pumpkins:
If I was ever to put pumpkin in a beer again, I would forgo peeling and roast instead of boil it to make things easier on myself.
Oh, and rice gulls. Plenty of them...
My mashes were gummy as hell.
Mine too. I had to reset the grain bed no less than 3 times for each brew due to stuck sparges. I ended up adding 1kg rice gulls by the end of the second brew!
This picture is a wee bit terrifying. I can feel my first stuck mash coming on.
If you find that one terrifying, here's what it looked like at the end of sparging the brew on the Craft Brewer system!
Luckily, aside from getting stuck right at the start, the sparge otherwise went well, albeit slowly and inefficiently.
