I am still new to the hobby and have been making wine since September. I am about to start kit #10. If you are only making one kit at a time, I don't think the extra carboy is necessary. I would spend the extra $40 and go for the Deluxe Package George has. The bottle tree, the vinator and the mix-stir are well worth the extra money in time saved cleaning your bottles and degassing your wine. I find the better stirrer saves time and energy in removing the CO2 from the wine. The vinator makes it a breeze to get cleaner and santizer in your bottles while the tree gets them to drip dry.
Using the Buon Vino is truly wonderful and efficient but not a necessitiy if money will not allow for it. Just be prepared for a little dripping from the cane and practice with it before using.
I hope you know what you are getting into, this is a very addictive hobby...Edited by: Lenore
