Yes, it's quite striking to drive from say, Como into Switzerland which is a very germanic culture. The towns, organized landscape, and even music on the radio change dramatically - like going from a hand painting to a computer model.
In the central valley of California, along the 5 and the 99 from Stockton to the Grapevine, there are tens of thousands of acres of wine grapes the vast majority of which are “bulk grapes” owned or controlled by the usual names – Gallo, Constellation, The Wine Group, Mondavi, Trinchero, etc. They make wines from very low cost grapes that people love – Barefoot, Apothic, Woodbridge, Sutter Home, Yellow Tail, and dozens of others that you may like and not even know are from these companies.
A statement of the obvious - In order to make these wines from low grade grapes, which are subject to yearly variations from nature, many manufacturing processes and interventions are required. I wont say they are processed within an inch of their lives because that would be rude. The point is that processes and additives exist to drastically alter your wines should you wish to do so.
There are also situations where higher grade vineyards and wineries have product they cannot move through their normal channels and must “bulk out” their grapes or wines to the buyers of last resort where there seems to be an endless demand for cheap, predictable wine. In 2019 many vineyards here in SLO County had to do some hard math – harvest and bulk out or let fruit die on the vine. Wineries that have sub optimal wine must also decide – additional interventions (which is an entire separate industry and not cheap), or bulk out. If you are an owner-operator winery faced with either insolvency or intervention……
Even if their wines are good, wineries don’t always have buyers for all of their inventory at their established price-point, in which case they can sell to independent third parties who bottle and sell under their own label (with NDA’s to not identify the original source winery). One example of this is de Negoce, whose business model is to negotiate a quantity and price with the winery and before even taking delivery/bottling they sell-out to their customer base who pre-pays in advance. I usually have a few cases around for parties and gifts. Although they are prevented from explicitly naming their sources, the descriptions are sometimes a give-away, the discount becomes obvious and you end up with a $1,000 case for $120.
I apologize for the tangent, the main point I wanted to make was – enjoy making your wines your way and then enjoy sharing and drinking them. Most people focus on color, taste, body, mouth feel, etc. and those things can absolutely be altered – even by the home wine maker. Some people focus on “100% natural” or minimal intervention. Some people have wine making in their family and culture that goes back many generations and it’s part of how they live.
Cheers to all you good home wine makers!
