An excellent discussion and ergo, the provocative question to Tom above.
He wrote:
Wine-making is a business, and the bottom line rules...
Isn't that typically the case? Without my romanticizing of the Port Trade (occasionally guilty, yes!

) let's explore some more. IMO, there are two key discussion points that arise from this quote.
1. The first is the thought that profits come before the quality of the Port that winds up in the bottle. I realize this is not exactly what Tom said, and it is very possible that it is a stretch to even allude to this as what he was referring to. However, one can not read that quote without thinking that considerations to quality would be compromised if they would upset the bottom line. This goes against everything I have ever seen in my visits to the motherland. This can be an entire separate discussion if you'd like, as it is pertinent if not important to understand many of the underlying realities that take place behind the scenes which we are not privy to. So let the topic continue or split it off in another thread?
2. Overlooked is the second discussion point, at least, from my point of view.
Port Shippers (as we think of Taylor, Graham, Sandeman, Cockburn etc... ) may still drive the Vintage Port market, but these powerful enterprises no longer make up the majority of Port
producers. There are a bunch of medium sized as well as MANY small and little known producers of Port, including VP, that together make up a much larger number than Shippers. They may not export as much, nor have the sheer power, but their numbers are very considerable ... even though the quantity of hectares under their control pales in comparison to the likes of some of the giants that control 90+% of the Port vineyards planted.
That as a given, it is vital to understand that the entire process begins with the quality of the grapes. I realize this is a very simplistic statement, but there are nuances important to glean from this. This will segue back to Tom's quote nicely, I promise! OK, the vast majority of grapes that make up a Vintage Port ... even those from the aforementioned major Shippers (and all but SQs of course) come from purchased grapes, NOT those grown on their own Quinta properties. Surprised by this? I am sure some reading here ... are, especially those who have not been to see this in person.
More critical, is the fact that these growers who own typically less than 5 hectares apiece; who live in one of the most remote wine regions in the world (there is
NOT A SINGLE INDUSTRY IN THE 100+ mile REGION beyond wine and a new and fledgling tourism effort) have NO other way to make a living than by growing grapes. Their parents also grew grapes and their grandparents did and so on and so on and so on ... going back centuries. In other words, these are not winemakers per se ... they are subsistence farmers. Yes, I realize this gets down to a very touchy subject in Portugal, but there it is.
These grape farmers have no choice but to put every possible piece of blood, sweat and love into their grapes. If the sun don't shine and the rain falls and a harvest is lost, how will they feed their family next year? I will avoid going into "the reason why co-ops exist ... and some even thrive ... in the Douro" as it takes us too much off course and into a truly financial direction (not to mention why many growers became Port and Douro wine producers themselves!). I prefer to slowly drive back towards Tom's quote though. :hello:
So these grape farmers who sell their grapes (or in rare instances, their fermented Port juice) to the larger Port shippers, have a great incentive for putting forth the BEST QUALITY grapes they can produce. It is money, so Tom is right that profits rule the day. However, it starts much earlier in the process than others above had suggested. It starts with the growing of the grapes, although of course, it does not finish there. Back to the growing and the fact, that
the grape farmers are paid an "incentive" or higher price per hectoliter of grapes sold, for delivering grapes at a higher Baume (same as Brix in the USA) simplified as residual sugar (RS). For those not sure, 1 hectoliter of grapes per hectare produces approximately 133 bottles or 11.1 cases of table wine and this varies with Port due to the fortification process, adding 20% Aguardente). I won't get into specifics of pricing, but suffice it to say, that sweeter grapes bring the farmer more money and the difference will typically equate to something quite considerable for the typical Duriense family.
My circuitous spewing is almost complete. Given that the only way to earn a living is by selling grapes, and that extra money can be earned by delivering a higher quality grape to the Port shipper that WILL (either contractually or much more often ... on a handshake) ALWAYS deliver this "bonus" to their growers ... why would the Port Shipper then NOT make the very best Port out of these grapes every single time they can?
Beyond tradition ... which should not be overlooked ... there is CONSISTENT QUALITY, as the mantra of the Port Shipper. It is not "bottom line" PROFIT as suggested in the aforementioned quote. They take the best grapes they can grow themselves, supplemented by an ocean of purchased grapes and put them into their Ports each and every year. What good does it do the reputation of the "brand" if quality is not stable and at a high level? Whether that is a Ruby Reserve, LBV or even the critical Vintage Port, I am convinced to my core ... that there is no incentive or bottom line pressure to ever let anything but the very best Port make its way into the bottle. The decision is not about the bottom line ... as the Shippers know that specific dynamic will take care of itself if they put the best Port possible to the marketplace. Of course I am over-simplifying things with that last statement, as market forces of all kinds, come into play. However, the crux is still valid.
Port makers and growers, can and do make mistakes and bad weather can and does happen, so that can certainly change the quality of Port from a single harvest. But the consistent high quality over the years, decades and centuries is what builds tradition AND profits in the Port trade.
A long winded and simplistic view.
