Method:-
Press the apples and grapes so that you have a 1/2 gallon of juice from each. The measurements should give you equal amounts of juice, but this may vary depending on the juiciness of your fruit.
Pour the grape juice and apple juice into a fermenting bucket.
Add in the sugar, citric acid, tartaric acid, tannin and stir until everything is dissolved.
Take a hydrometer reading and save this for later, this will give you an approximation of the finished alcohol content, if you would like it a little stronger, then add a little more sugar.
Add a crushed Campden tablet and the Pectolase. Cover and leave for 24 hours.
Stir in the yeast and yeast nutrient.
Put the lid back on loosely and transfer to somewhere luke warm (approx 18°C) for 10 days.
Transfer the liquid into a demi-john to the top of the shoulder. Fit a bung and airlock (half filled with steriliser water) and transfer to a cool corner in the house, ideally between 16°C and 18°C to allow for the the fermentation to complete. This can take up to 6 weeks.
Once the fermentation has completed, rack the wine off the sediment into a clean, sterilised demi-john. Add 1 crushed Campden tablet and the fermentation stopper (as per the instructions) and stir.
Refit the airlock and leave for 48 hours.
Add the wine finings as per the instructions and allow the wine to clear.
Once clear, take the final hydrometer reading. This will tell you the proof of your finished homemade apple and grape wine.
Bottle and ideally leave for 6 months for its full flavour potential to be reached.
