How to Make Japanese Plum Wine!

In japan, is currently Plum season. I should say "Unripe" plum season. Yes, because the only plums on sale, are green, uneatable, plums.

This plums are used to make Plum Wine. I'm always amazed how in japan, everything is organized by "Kit". What I mean by "kit"? Well, besides the instruction sheet above, check this out:

This is the kit to make plum wine. As the instruction states, for 3.6 Liters of Plum wine (not 4!! 3.6!!) you need:

2.0 Kilo of plums (guess what! Already sold in 1kg-sized bags!)
3.6 Liters of Sake (guess what! every bottle is exactly 1.8 L!!)
1.0 Kilo of Fruit Sugar (Notice that the bag has Plum wine on it!!)

Once i've got all the necessary gear and ingredients, i start opening up the big Jar that will be the new home of my plums for the next six months!! (yes! 6 Months of waiting!):

Wash, clean and make tiny holes in each of the plums...

Once done, put all the plums in the Jar, add the sake and the sugar...

Now, once closed, the jar has to stay sealed for 6 months...and once a day need to be turned upside down a few times to keep the sake and the sugar well mixed...

The total investment was 5,200 yen (55 Swiss francs) for about 4 L of Plum wine. In shops, the plum wine costs about 20 swiss francs for 1.5 Liters...but the just have few plums ;)... besides... we would miss all the fun, woudn't we? ;)
