At this point I believe a general wine making flowchart will help. This is intentionally simple as the details can be overwhelming for beginners.
Also note that there is a room for variation and personal choice in wine making -- most things have a range of choices, all of which are correct. Some prefer something, others prefer something else, yet both are correct.
1. Crush grapes and inoculate with yeast in an open, food-grade container. Cover with a towel to allow air flow while keep large airborne things out.
2. Stir once or twice daily, breaking up the cap and submerging it. A dry cap is where undesired "stuff" grows. I stir wine daily even when it's just juice.
3. When the SG is between ~1.010 and ~0.996 (fermentation complete), press the grapes. This is an area for differences of opinion -- if the SG is in that range, it's fine.
This will typically take 4 to 10 days, depending on many factors. 6 to 7 days is typical.
4. Put the wine in a glass or stainless steel container under an airlock. If the SG was above 1.000, allow head space (air space) as fermentation is not complete. If it's below 1.000, fermentation is done or very close, so allow small head space.
When I press at 1.010, I typically allow 6" to 12" of head space, as fermentation is active and solids can blow through the airlock, making a mess. If fermentation is done, I allow 2" space from the stopper.
If you have too much head space, top with a compatible wine. If making Cabernet Sauvignon, use a good tasting Cabernet. If its an oddball grape, use a neutral (non-strong tasting) white wine. You are not adding enough to make that much difference -- far less than oxidation if you have too much head space.
5. Rack again in 7 to 14 days. Check SG to determine if fermentation is complete. A lot of sediment will normally drop. Rack the wine off the sediment, clean the secondary fermenters, and put the wine back in.
Add 1/4 tsp potassium metabifulfite (K-meta) per 5 gallons of wine, or 1 Campden tablet (crushed to powder) per gallon for smaller batches.
Add K-meta or Campden at every racking after this, including bottling time.
If using a fining agent, this is the time to add it.
Keep head space to a minimum. I keep a large selection of smaller bottles so I have something to put the excess in while keeping head space to a minimum. Early in the process, my wine making area is a sea of air locks.
6. If using a fining agent, rack again in 10-14 days as a lot of sediment normally drops.
7. Rack again in 1 to 3 months.
8. If after 2 weeks there is no sediment, you can bottle.
There are good reason to bulk age for 3 to 24 months ... but none are mandatory. It's your wine, do what you want. No one else's opinion (including mine) matters. Just don't bottle until the wine is clear.
