OK,
Lets start out by assuming that you want to make about 100 liters of red wine from fresh grapes...
First you need to obtain the fruit. for 100 liters, you should need about 360 pounds of grapes. (100 liters is 12 cases of wine).
To start out with, you will need a crusher/destemmer. This device (around $500 to $600) will be the most expensive piece of equipment that you need to get. The good news here is that they last forever. I have been using mine since 1995 and it is still in great shape. The crusher/destemmer will first remove the grapes from the stems, then lightly "smoosh" them.
From the crusher/destemmer, the grapes go into a primary fermentation vat. This can be as simple as a couple of "brute" garbage cans which are thick, sturdy, and food safe. You can get them from any lowes or home depot.
After a week, it will be time to press your grapes. For this you will need a press. These can cost anywhere from $250 on up. The bigger the press, the more expensive it will be.
From the press, the wine needs to be placed into a secondary fermentation vessel. This can be either a carboy (glass 5 gallon jug), a demijohn (glass 54 liter jug), or a tank (from 100 liters on up). Like everything else, the bigger it is, the more expensive it is. For 100 liters, I would suggest 2 54-liter demijohns. This should run you about $60 or $70. to seal the demijohns, you will need stoppers and fermentation traps. You will also need 2 or 4 single gallon jugs to hold any "over-run" that does not fit into your demijohns.
As far as ingredients (other than grapes) you will need..
10 packets of yeast. I am a big fan of Lalvin RC-212
1 lb of yeast neutriant
1 lb bag of K-Meta powder.
1 lb bag of tartaric acid (to be added if your acid is too low).
You will also need (most of the following is under $10...
Acid test kit (to measure the acid in your wine)
hydrometer (to measure the sugar in the wine)
syphon hose / racking cane
oak cubes (optional)
corks and a corker
bottles
bottle filler
The above should cover it. It is kind of "bare bones", but I think that I have listed the essentials.
