Hello all! I have a question. I am making Cellar Craft Showcase Rosso Fortissimo and noticed that there isnt cubes of oak like in Eclipse series but a sawdust like powder. Now the store I purchased this at sells cubes. Would you reccomend not using the powder but instead using cubes? One other question. Do you prefer to use the grapes skins in the bag or let them free float in the primary fermenter? Anyone have good results with this kit? THANKS!
