Hello Jose.
When making wine from juice or grapes, my advice is to bottle when the wine tastes good.
Over many years I have experimented with the concept that "it will get better with time". NOT. You are just wasting corks.
I rack about a week after fermentation is over, then 2 weeks, then a month, then every 3 months till I bottle.
I bottle when it tastes good and there is just a skim of sediment on the bottom of the carboy.
I use oak cubes and add them after my second racking.
Racking pulls off CO2.
You can check your bottle of wine for CO2 by pouring a glass of wine.
Then put your thumb on the top of the bottle and shake the bottle.
If your wine has CO2 it will have a lot of bubbles.
Then you know you should have racked a few more times before you bottle.
I use oak cubes to add flavor, glycerin to add a bit of body (remember to add Sorbate when you do this)
If your wine needs help play with a teaspoon of vanilla maybe! Organic blueberry juice is a great ingredient to add some flavor.
Ya Ya, purests schmurists, if you end up with some Chilean that is not working out, be creative.
Good luck!
Cheers
