Myth 1: Only warm, sunny days are good for grapes

Sunshine is important – but cool nights are just as crucial, as they preserve the grapes' freshness and acidity. Rain at the right time can also be good for the vines. A balanced climate is what determines quality, not just heat and sun.

Myth 2: The later you harvest, the better the wine

This sounds logical, but it's not always true. Although grapes gain sugar and aromas as they ripen, they can also lose acidity. In addition, the weather, variety and style of wine play an important role. So finding the perfect moment is an art in itself.

Myth 3: All grapes are harvested on the same day

Not at all! Each variety has its own ripening time, and there can even be differences within a single vineyard. That's why the harvest often lasts several weeks. Sometimes white wine is harvested, sometimes red wine, and some varieties are deliberately left on the vine longer.

Myth 4: The grape harvest is purely manual work

Only partly true. In Switzerland, many grapes are indeed harvested by hand – especially on steep slopes or with delicate varieties. However, there are also machines that are used on flatter plots. Ultimately, the topography, the grape variety and the philosophy of the winemaker are the deciding factors.

Myth 5: Grapes can be drunk immediately after harvesting

Unfortunately not. Freshly harvested grapes are sweet and juicy, but patience is required before they can be turned into wine. After pressing comes fermentation, then maturation. It is only weeks or months later that the wine ends up in the bottle – and in the glass. If you want to try something straight after the harvest, you are more likely to get fresh grape juice or the young ‘Federweisser’.

Myth 6: After the harvest, the work in the vineyard is done

Not at all. After the harvest, the real work begins in the cellar: the grapes are processed, the must ferments, and the young wine is cared for. At the same time, the vines are already being prepared for the next vintage. The grape harvest is therefore not the end, but rather the highlight and starting point for the next wine.

Myth 7: Only professionals can help with the grape harvest

Wrong. Many winegrowers welcome volunteers, whether they are beginners or experienced. The work is explained, and it is easier to tackle it as a team. This makes the grape harvest an unforgettable experience for everyone.
