The food from the Netherlands is tasteless compared to Spanish or Italian in all seasons of the year, in the summer, all produce in Europe beats it.

High yields in a country that does not have record sunlight throughought entire year, can only be achieved by abusing chemicals in the process, faking natural conditions, etc. Low amount of natural sunlight can easily be tested using your taste buds.

If their farmer switch to other varieties, without slowing down and reducing the yields, they will still harvest tasteless produce in comparison to other countries that have better conditions or "slower" production.
