Why are glasses of wine in CH only 1dl?

Because the Swiss get drunk very easily. So it limits their intake

Just wondered if it has anything to do with the alcohol limit for drink diving here.

Have known several people caught out. It is random when and where they check but the consequences can be quite off putting.

Doesn't apply, there's no such thing as a "standard pour" here. In Swiss restaurants the glasses and pots are calibrated, if you order 2dl that's exactly what you get.

Without wanting to go all Tom, I was at a restaurant in St Gallen last week where not only were the prices per dL pleasantly cheaper than Zurich, but my DL pour was straight from the bottle and more like 1.5dL

I think the answer is pretty obvious: Swiss consumers arent very price sensitive, but that does not mean they are completely ignorant of them - its apparently the 10 CHF mark every bar wants to avoid... so they portion the wine accordingly that a glas costs some 8 CHF even in downtown Zurich. Some bars like Moevenpick go so far that the price remains around 8CHfs, but the amount varies depending on the wine. Some come in 10cl, others in 15... so no matter if you buy cheaper or more exoensive wine, a glas is about the same and the amount varies.

P.S: Went to a wine tasting with some Swiss friends here at the Mosel and they were shocked that you can get good quality white wines from small batch producers for 6 EUR a bottle...

How does that contradict what I wrote? You ordered 1dl, that's what you got (plus a free extra), and what you paid for.

And then there's this thing, when the waiter/owner likes you

1dL of wine at 12% Alcohol content is 12ml of Alcohol = 1 Standard drink.

The driving limit is at 0.05%Alcohol in blood = 2 standard drinks.

The maximum recommended alcohol intake per day is 30ml in CH, 24ml in Germany, 40ml in Italy, 20ml in the US.

So 1dL is a normal drink.

So if 1 dl is a normal drink: Why do wine bars in Zurich sell the cheaper wines in portions of 1.5 dl and the more expensive ones in 1dl? Surely the alcohol level is not 50% different between the cheap merlot and the good one...

I think that I have an alcohol problem!

1 dl would not even whet my whistle.

Maybe soon we need to buy this stuff in an Apotheke?

Queue up behind the methodone guys.

I will align with the Italian guideline then .... unless you have an even better one.

I don't remember seing many people drinking "Tschumpeli" as seriously it's a sip = just a tease. They must have tried to serve me that at one point though as I automatically always order a "Zweierli". (2 dl)

Not in Turin. A "glass" of wine there was significantly larger than the damp glasses they serve you here.
