Welcome to the forum, NorCal. I, too, moved from Classic Cars hobby to winemaking about 4 years ago. You will find that it is a lot less expensive hobby! No more do I have to pay $500 for an air cleaner or $1100 for a Stromberg EE-22 carburetor! I would also mention that my wife never got behind the old cars but she does like the wine!
Tell us a little more about what you plan to make. You say that grapes are readily available to you and that you plan to make 40-60 gallons per year. Do you envision making one or a couple varieties or small quantities of a number of varieties? Do you plan to make wine only from fresh fruit or will you also use kits and juice buckets? What type of facility do you have available to you in which to make wine, i.e. temperature and humidity controlled, space available, etc.? You are in one of the best areas of the Country for winemaking so your entry into the hobby should be easy. I have found that winemaking is a science, the outcomes of which would be totally predictable if and only if we understood the myriad variables (which few do) and therefore we practice it as an art.
I live in a little community with a working vineyard and have access to purchase cab franc, petite syrah, grenache, mourvedre, petit verdot. Most the residents enjoy the ambience, I see the challenge to learn to make some really good wine. I would like to make a variety, and play with blending, but could also see making single varietal batches as well. The only space available to me would be the space vacated by my current and finished project car. Temp and humidity control is an issue and that is definitely something that I will have to figure out by this time next year. Here is my list thus far.
Crusher/destemmer (make, buy, borrow or rent)
Fermentation vessel
Press (make, buy, borrow or rent)
Pump with filter system
Storage vessels, bungs, air locks,
Corker
Analytical instruments (hydrometer, thermometer, ph,so2)
Cleaning, sanitation supplies.
Cold storage (make)
There is a resident that makes excellent wine and I'm hoping that between what I can learn on my own, along with his advice, I can make something drinkable. I helped him last season on the front end of the process, so I have some idea on what I am getting into.
Rocky, it sounds like you were into V12 Lincolns. I was mostly into 64-66 mustangs, but also dabbled into British; Austin Healey 3000, TR6
