    Any input will be appreciated.... this will be a pumpkin imperial stout that the 2nd half will be partigyled into a pumpkin stout. Hows it look? Looking for a slight flavor of chocolate (sort of like TREAT), some dark flavor but not a sharp coffee/burnt taste more like a pie crusty flavor.

    Also: too much lacto in the mini stout? dont want too much sweet that its like a milk stout.

    Pumpkin Imperial Stout:
    OG: 1.107
    Est FG: 1.030
    Est Abv: 10%
    IBU: 76
    SRM-35

    Grain:
    • 2- Row- 16lb (75%)
    • Roast Barley- 0.75lb (3%)
    • Choc Malt- 0.75lb (3%)
    • Spec B- 0.25lb (1%)
    • Crystal 80 1.5lb (7%)
    • Crystal 120 0.75lb (3%)
    • Carapils 1lb (5%)
    • Biscuit 0.75lb (3%)
    • Rice Hulls 2 lbs

    Hops:
    • 2oz EKG @ 60
    • 1oz Fuggles @ 60
    • 1oz- EKG @ 30
    • 1oz Fuggles @ 30
    1 tsp yeast nutrient @ 10
    1/2 tsp pumpkin pie spice @ 5min
    60oz (2 cans) Pumpkin baked 1hr to carmilize with 1 lb brown sugar and pumpkin pie spice
    Mash pumpkin with grains at 154 degrees x90 min.
    Hit with 1 in pure O2 when transfering to bucket and again 12hrs later before fermentation takes off
    Pitch on an old yeast cake of S-04
    Transfer to secondary after 3 weeks, add 1 fresh vanilla bean and few cubes of bourboned oak, sit for at least 1 month.
    Going to make a "pumpkin spice tea" of 2 tsp pumping pie in Capt Morgan to add at bottling if I think it needs more pumpkin spices
    (planning on having 5 lbs of dark DME on hand if my tun doesn't have enough room for everything, to substitute for some 2 row that will be held out of mash)
    2nd part (partigyle of second runnings)

    Pumpkin Stout
    Guestimate:
    OG- 1.064
    EFG- 1.020
    IBU: 5.65
    IBU- 46
    SRM- 26

    Second runnings, will have some DME to bump up the gravity if needed
    Lactose 8oz
    Hops:
    • 1oz EKG @ 60
    • 1oz Fuggles @ 60
    • 1 oz EKG @ 30
    • 0.5oz Fuggles @ 30
    • 1/2 tsp pumpkin pie spice @ 5min (Will have "pumpkin pie spice tea" if needed at kegging.)
    Yeast- S-04
    02 when added going to bucket.

    Personally, I wouldn't add carapils to the recipe. I think you'll have enough unfermentables to carry you through your parti-gyle. Did you say this is going to be a 2.5gal split for each recipe? Otherwise, you'll end up short on your gravities.

    Gordon Strong recommends adding some extra specialty malt into the second runnings to help keep the beer from tasting husky and grainy. I've always added extra specialty to the second runnings and I've had great luck. It also helps the beer taste different than the first. :slight_smile:

    Edit: Your lacto is fine for the second stout and I'd also drop your mash temp to keep either of these beers from becoming icky sweet. 152 is all the higher I'd go.

    No, its supposed to be 2- 5 gallons. I now see where I went wrong. Thank you, I was misreading the tables on Mosher's site- http://morebeer.com/brewingtechniques/library/backissues/issue2.2/moshertable.html

    - I was tossing around leaving out the carapils but wasnt sure I would have enough head retention w/o it.

    If you want a bready, crusty flavor, I highly recommend using Marris Otter as your base malt.

    Usually a high FG and a decent amount of crystal malt will lead to good head. I won't stop you from adding carapils, but it's going to start getting pretty thick when you do that.
