Bread was replaced by chapattis in the '76 bread wars, Luton North still retains an informal yeast autonomy but by and large all uprisings have been quelled.
Migros Deli-Fit Vollkorn (wholegrain) buns are great with a bit of Philadelphia spread and a sliced tomato. The only thing is you have to be there a bit before lunchtime or they are all gone.
Migros makes a sliced white toast bread called Pain du Soleil, which is great for sarnies. It seems to last longer than the Coop one with the American flag on it.
Buying bread in Migros or Coop is very good for your health. You have to run very fast to get home before it's gone rock solid.
However, the Coop olive bread is very tasty and stays moist for a while. As it should for something costing over 3Fr.
I often buy bread in Germany (Marktkauf) and France (St Louis Farmers market and Geant). They're all better, and last longer, than the Swiss supermarket choices, and are good enough that I've yet to really explore the bakeries near me.
I suspect that the local bakers in Basel will beat them all, apart from the St Louis market - that place is excellent and good value. It's a new experience for me to buy bread by weight though "Can I have 500g of ...". Interesting!
Try Migros Fit-Pain. That stays good for a good couple of days in a sealed box. I think it's made with soya and maybe some other grains but it seems to stay moist for a bit longer than the other varieties.
I've convinced myself that the Swiss bread has less preservatives in it than the plazzy bread you get in the UK which is why it goes stale so quickly...
Most loaves of bread I buy here last for 3 or 4 days if I put bread and paperbag all in a plastic bag (pressing out as much air as possible), twist up the opening and bend it under. You can even 'refresh' a day-old, gone-soft Gipfeli by halving it and popping the two halves in the toaster for 25-30 seconds.
Almost any bread from the "holzofenbaĢkerei" in Winterthur. Super! Coming from England I don't really understand why people miss the bread from there. The beer maybe...
As I remember, supermarket bread or highstreet baker's bread in the UK was always pretty crappy and unless you lived near an artisan baker or a farmer's market, you were punished on a daily basis.
I once had a cob loaf from Waitrose which was still soft, rubbery and tasteless after 10 days......
