The above question does not have a simple answer. There are many aspects that have to be taken into consideration. For instance, I first noticed that strawberries grown in my garden in Teufen (about 900 m/3,000 feet above sea level) had less sugar content that the same variety grown in the Engadine (about 1,500 m/5,000 feet above sea level). I wondered if this could be attributed to the humus in the soil of the Engadine moors or to the intensive sunlight there. Interestingly, I also noticed that the sugar content of the lowland strawberries increased if the summer was a warm and dry one. I had to conclude from this observation that warmth and sunlight are mainly responsible for sweetness. Feeding also plays an important part; our strawberries are given a sufficient quantity of organic lime, which would account for their being sweeter than if the soil was not fed at all. So then, various factors must be weighed up before we can come to the right conclusion. By the way, carrots also do better in the Engadine than in Teufen, being sweeter and better flavoured. For this we must not only thank the strong, warm sunshine but also the higher elevation of the Engadine, its excellent climatic condition, and the richness of the soil.
