It’s gotten better over the years as consumer awareness has grown but now there’s the trend of making fruit increasingly sweet like cosmic crisp apples, sumo mandarins, or cotton candy grapes.
Then you can sort all the oranges by sweetness, and sell the sweet ones to one place and the pretty ones to another.
Where the consumer only sees the looks in the shop, why send that country the nice tasting ones?
Try an aubergine in Germany, and then try one in Sicily. The difference is stark.
My biggest annoyance is ordering a BLT in August and getting a green artificially ripened tomato even though ripe and flavorful ones can be found everywhere. You would think that CSAs would be a lot more popular and successful then they are but the reason (imo) is that most people really don't want to cook and even if they do, they don't want to do that every day so the CSA shares end up overwhelming them with fresh supplies that get given away or thrown out instead.
The logistics between growers to distributors to store and customers add a ton of cost to your food. In the order of 200%.
The reliance on external food sources for many ingredients exacerbates this even more.
Many business models in other countries are based on lowering logistics, doing basically grower-to-customer directly and evading all the middlemen. No refrigeration, better quality, cheaper food.
The mom came to visit her daughter during COVID and while eating something bought from the local supermarket, she noticed that the food has a very weak taste if any at all. COVID was said to impact one's sense of taste or smell. So, upon returning to France, she went to take a test and... she didn't have COVID. In fact was completely healthy :)
I went to France last summer. And... truth be told, I don't taste the difference between Dutch vegetables and French vegetables. To me they are both fine. The bread on the other hand is on a completely different level.
Anyways. I don't really know what may be causing these perceived differences in taste. But, I have a theory that it's a learned thing. Maybe our sensors adapt to a particular food and then a very small change overall can affect them in a major way?
