We are harvesting the last of the grape harvest. It’s been a long vintage this year, stretching over 8 weeks. We have been making dark grape juice out of most of the vintage. However, with these last few baskets full of rich dark red sugary deliciousness, we decide to make ‘Summer Wine’. We first came across this wonderful stuff in France, then Germany, followed by Switzerland and finally in northern Italy. As the season developed and the grapes ripened. We had to have the experience introduced to us by our hosts in Germany at that time. We stopped the car on the side of the road to buy vegetables and fruit from a farmers road-side stall. Our friend asked if we had tried ‘Niue Wine’ or ‘summer wine’? We hadn’t, so we did and it was a bit of a revelation.
We have been making our version of concentrated red grape juice for a few decades and always look forward to it. We manage to bottle 20 or so litres each year for us throughout the year. We pasteurise it so that it will keep and not ferment. Then sealed in sterilised glass bottles. It works well. But this was an eye opener.
We don’t make wine from our red grapes, because it is too much work for the reward. Good quality wine is cheap in Australia, why bother, but good organic red grape juice is extremely expensive. So thesis where we put our effort. What we experienced in Europe that autumn was just like our red grape juice, but very slightly fermented, possibly for just a few days. The outcome was a sweet grape juice with all the fruit flavour, but also enhanced with a little sourness and tingley, cabin dioxide induced spritzig. I might hazard a guess that it was fermented to about 2% or so of alcohol. It was a light, really refreshing and satisfying draft.
We have since started to make a small batch of summer wine each year. It has to be drunk within a few days of the fermentation starting, while it still has plenty of sugars left in solution. We asked about the roadside wines that we saw and were told that it will only be available for a few days from each stall. Once the barrel is emptied, then that’s it. find the next farmer’s stall.
They might possibly use the wild natural yeast bloom on the grape skins, but this can be very variable. Because we don’t know what we art doing, and don’t have parents and grandparents on hand with generations of local knowledge about such home based, home-grown, organic production. We decide to pastures the juice as usual and then add a known wine makers yeast to get a more-or-less predictable and reliable outcome.
We wash and de-stem the grapes to make the juicing process easier. Either way it is a lot of work. This is just the way that we have got used to doing it over the years. After sterilizing by briefly simmering the juice, we let it cool over night and then add the yeast. , somewhere between 16 and 24 degrees C. We let it sit for a day to allow the ferment to get going and then bottle it. We start to drink it from the 2nd day. After the third day, or when we feel it has reached a good point in the sugar/acid balance, we bottle it and keep it in the fridge to stall any further fermentation. it keeps for a week like this. and then it all gone. If you try this at home, don’t screw the caps on. LEAVE THEM LOOSE.
