How to make wine?

[herecomesthesun]

I have fermented berries, but I don't know what to do with them. How do you make wine?

Hi! You can not make alcoholic beverages with the berries yet, but they do last much longer when fermented!
If you want to make wine, at the moment the only way is to extract sap from birch tree and ferment it into wine.

Okay. Thanks so much for the response!

How exactly does fermenting sap work? It spoils to unsafe water over time and liquid quantity reduces under heat.

You need to collect the container while the sap is still fresh, then put the sap in a fermentation jug. Over time it will convert to wine, if the sap has enough durability left.

Boiling the sap will convert it to syrup; the sugar content will go up but the volume will go down (basically, you are concentrating the sugar by boiling off the water).

I collected sap straight into a fermentation jug and it still turned to unsafe water...

That might not work. You may need to trigger the fermentation step by putting the sap in all at once, because if you just put the fermentation jug into the tree, new sap gets added every tick, so the fermentation timer keeps getting reset. You want to start a separate batch of wine for each batch of sap (you can move the wine out of the fermentation jug once it is complete, to free up the jug for a new batch).

Also, you can boil down the sap a bit before adding it to the fermentation jug to increase the sugar content; this will give you stronger wine. (Boiling the wine, on the other hand, will evaporate the alcohol and make it weaker.)

Ugh, that sounds like a lot of work... Maybe I'll skip it for now until I find some birch closer to my base.

Probably a good practice would be to have several jugs and switch them once one is done fermenting. I didn't try yet, but there's probably a number of jugs beyond which it is trivial to know that, if the least recent one is done fermenting, it necessarily means you can go look for your new batch of sap to replace it.
