My weekend plait (cooled) weighs 512g today ... I get it from a home bakery in eastern Switzerland.

The problem often occurs with Jowa breads.

My last weighings: 242g, 246g, 241g, 258g,
225g ????
I admit defeat and will do without the bread in future and post this in Aldi. It really can't be down to storage, the 40 or so 250g loaves are already sold out by the afternoon. A lot of money is made with air if you extend this to the whole of Switzerland first. For me, this is clearly cheating the customer, there's no other way to put it. It should be 250g on average, which is really wishful thinking here and certainly not the case. It would be so easy to weigh a batch to determine this, so I am firmly of the opinion that money is being generated here with air to the detriment of the customer.

It's just sad what Migros does. And if you complain, you'll be brushed aside.

Only weighed the organic Buttergipfeli today... Should be 45g - is 46g ? Almost a bull's eye, although in my experience the small loaves are always a little "too heavy"...

At MMM Neumarkt in Brugg, the loose cookies are all sold without a gram. Here you pay the unit price.

But yesterday, Sunday, I bought a 500g Ruchbrot at the Coop Langhaus in Baden. This bread weighed 499g, which is absolutely in line with the rules. The price is also right, twice the amount costs exactly 25 centimes more than the underweight 250g Ruchbrot from Migros. The taste is the same.

We will continue to keep an eye on this topic. :-) That is/was probably the joke of the day.

So on average 10g of these 250 grams are missing, as 2.5 grams is 1%, so that would be 4% I think that is still acceptable, just my opinion.

>So on average 10g of these 250 grams are missing
Not even that. If I take the values from wheid (from this page and the two from the start posting) ...
>>> mean([242, 238, 242, 246, 241, 258])
244.5

... just 5.5 grams are missing on average, i.e. ~2%. Incidentally, the uncertainty on this value is +-2.65g.
Are the breads really not weighing 250g on average? Well, according to this sample, they are really too light with ~95% certainty. But only on the condition that the scales are absolutely accurate. Even a small systematic error can negate all of this - yes, statistics are fun?

But let's assume that the mean value is correct. Then you are paying ~2 centimes too much per loaf(250g cost 0.90). I don't know how much bread you eat, but a lot of water flows down the Aare, as they say in good Bernese German, before it adds up to a significant amount. Buy M-Budget once instead of M-Classic (or even Bio/Selection/...) and you'll have that back for a month.

The lightest bread was just 225g! And I don't care how much money I lose. What really annoys me is the fact that people are cheating, even if it's just about legal. On average, the bread should really come close to 250g, sometimes 2 to 3 grams more, sometimes 2 - 3 grams less. But that's far from the case, unless I'm unlucky and always get the 'wrong' loaves.
I am in the fortunate position of being able to buy organic vegetables and meat. One thing is for sure, the price is always organic, but I'm beginning to doubt whether the products are. Nowhere is there more cheating and trickery than in the food sector, which annoys me immensely. The lobby has our politicians firmly in its grip and everything is done to ensure that the regulations and laws allow a lot of (too much) leeway.
In this case, I'm not going to be dazzled by rappels and percentage minimum units, I simply hate being cheated. Even if I am alone in my opinion.
But today I was amazed when I realized that the same 500g Ruchbrot is available for Fr. 1.15, compared to the 250g at Fr. 0.90. Both loaves are in a paper cellophane wrapper, so it can't be the packaging. A somewhat strange pricing whose origin is probably to be found in marketing.
