"A friend told us about Pumpkin wine they tasted at our Pumpkin
Fest in Port Elgin Ontario, they said it tasted wonderful. Knowing
we had a few homemade recipes, they thought we might have this
recipe. We don't but maybe you have." John Moore, Canada
This essentially is Leo Zanelli's recipe and he swears by it. The sugar is high and will produce either an 18% alcohol dry wine or a lower alcohol sweet wine, depending on what yeast you use. If you want the high alcohol, use a high alcohol yeast such as Lalvin K1V-1116 (Montpellier) or Wyeast 3347 (Eau de Vie), both of which can handle the extreme sugar. If you want moderate alcohol but sweet wine, use Red Star Côte des Blancs for 13% alcohol with 5% residual sugar. For slightly less sweet, use Lalvin 71B-1122 (Narbonne), ICV-D47 (Côtes-du-Rhône), Lalvin Simi-White, or White Labs WLP730 Chardonnay White Wine for 14% alcohol and 4% residual sugar, or Lalvin AMH (Assmanshausen), Lalvin BGY (Burgundy), Lalvin CY3079, Lalvin ICV-D80 (Côte Rôtie), or White Labs WLP720 Sweet Mead/Wine for 15% alcohol and 3% residual sugar. Read the yeast descriptors at Strains of Wine Yeast for correct nutrient and temperature requirements for the strain you select. Begin this recipe in the morning so you have time to complete the tasks without having to awaken in the middle of the night.
Grate the pumpkin flesh mechanically (recommended) or by hand and set aside. Do NOT place chunks in a blender and attempt to chop them. Bring the water to a boil and stir in the sugar until dissolved. Remove from heat. Place grated pumpkin flesh in primary and pour boiling water over pumpkin. Allow to cool to room temperature and add finely crushed and dissolved Campden tablet. Cover primary and allow to sit 8-10 hours. Add pectic enzyme and allow to sit overnight. Next morning add citric acid, yeast nutrient, energizer and activated yeast. Cover primary and stir twice daily for three days, submerging "cap" as necessary to keep moist. Pour through a nylon straining bag and let pumpkin drip drain. Transfer to secondary and fit airlock. If you did not recover a full gallon of liquid, wait 5 days and top up as necessary. Rack after two weeks and again after additional 30 days, topping up and refitting airlock each time. Set aside for 3 months and then rack, stabilize, sweeten if desired (unlikely you will need to but...), wait 3 weeks for dead yeast to fall out, and rack into bottles. Set aside to drink next year at Thanksgiving or Christmas. [Adapted from Leo Zanelli's Home Winemaking from A to Z with major modifications by Jack Keller]
