Vineyards look forward to bumper harvest

The 2015 vintage could be a great one for many Swiss winegrowers, thanks to the hot, dry summer.

While fruit and vegetable growers complain about the lack of rain, vineyard owners canvassed by the 20 Minuten newspaper are very upbeat about this year’s grape harvest.

They are reminded of the record-breaking summer of 2003 when the harvest was two weeks earlier than usual.

“If it continues to be so hot we will have a top vintage,” winemaker Andreas Stössel told the paper.

Other winegrowers across northern and eastern Switzerland agreed.

Barbara Koellreuter from Aesch in the canton of Basel-Country is delighted with the condition of her vines, saying she expects “very good wine” this year.

“2015 is going to be an excellent vintage,” said organic winemaker Bruno Martin from Ligerz on the Lake of Biel, adding that he couldn’t wait for the harvest.

Far from damaging the vines, the hot and extremely dry weather of the past few weeks seems to have done them good.

The dryness has protected the plants from fungal infections and infestation by the spotted-wing drosophila fruit fly.

And winegrowers are less reliant on pesticides than usual.

“This year we have fewer problems with diseases like mildew,” Michael Teutsch from the Lake of Biel told 20 Minuten.

But it is too early to celebrate just yet. The weather between now and September will determine how good the vintage is.

As the grapes ripen the ideal temperature is around 20 C. If it is too hot the grapes will have a higher alcohol content but less aroma.

But Markus Hardegger of the St Gallen wine centre is optimistic: “Only hail can spoil things now,” he said.

Switzerland has 15,000 hectares of vines and produced 93 million litres of wine last year.

Climate crisis: Swiss lakes at lowest-ever August levels

Some of Switzerland's best-known lakes are at their lowest level ever for August after a dry year so far in 2022, the environment ministry said on Wednesday.

Climate crisis: Swiss lakes at lowest-ever August levels

Some of Switzerland’s best-known lakes are at their lowest level ever for August after a dry year so far in 2022, the environment ministry said on Wednesday.

At the same time, discharge levels on the Rhine, one of Europe’s major rivers which starts in the Swiss Alps, have never been so low in August since records began.

“There is a low water situation in Switzerland, especially on the central plateau and in the southern part of Ticino,” the country’s southernmost canton, said Michele Oberhansli, from the Federal Office for the Environment’s hydrology division.

“The reason for the existing situation is a precipitation deficit in the whole year of 2022, which affects the whole of Switzerland, as well as many other European countries,” she told AFP.

Soil moisture is down across the country and drought is affecting forests and agriculture, she said.

Lakes Constance, Lucerne, Lugano and Walen “are currently recording water levels that have never been so low in an August month since measurements began”, said Oberhansli.

Meanwhile Lakes Zug and Maggiore “continue to show values well below average”.

The shores of Lake Maggiore mark the lowest point in Switzerland, normally at 193 metres above sea level.

Except the lakes in the Jura region in the northwest and Lake Thun, the levels of all the other larger Swiss lakes are also below the long-term average.

Rivers down, glaciers melting

Meanwhile many Swiss rivers are recording readings that only occur once every two to 20 years.

“Discharge values on the Reuss and Rhine have never been so low since measurements began in August,” said Oberhansli.

The hydrologist said rain over the coming days should “slightly alleviate” the low water and drought levels, but would “not yet be sufficient to ease the overall situation”.

Following a dry winter, the summer heatwaves hitting Europe have been catastrophic for Switzerland’s Alpine glaciers, which have been melting at an accelerated rate.

A layer of ice — 15 metres thick in 2012 — has covered the Tsanfleuron Pass between two glaciers since at least the Roman era.

But most of it has gone and the ice on the pass will have melted away completely by the end of September, a ski resort said last week.
