I am making a white bread with 500g regular flour, about 300g water, sourdough starter, yeast and salt. It will rest and raise some time before being baked. Pretty basic.

Now I was wondering, what would happen if I used sparkling water. Will the bubbles do something to the chemical reaction that builds gluten? Or maybe create additional holes in the bread when it's done? Will the bread be significantly different from using plain water?

    Considering how quickly sparkling water goes flat and how long bread has to sit out to rise, I don't think it'd be sparkling any more by the time it goes in the oven... Plus, the acid in the water might retard the yeast performance... But this is all a guess. – Catija Nov 7 '15 at 23:57
  • It would conceivably help with (or affect, anyway) a quick bread. – Ecnerwal Nov 11 '15 at 13:19
  • @Catija hits the nail on the head: one can make plausible guesses. But (and I take this too to be implicit in the comment) we won't get a legitimate answer until the experiment has been tried carefully. A full answer will also require an interpretation of the results that gains broad adherence and agreement from food scientists and/or organic chemists. I would urge that no answer be accepted until then. – CAgrippa Jul 23 at 6:02

I am not a chemist, but my grandma always used to make bread (and similar stuff) with sparkling water instead of still water. She always mentioned that the result will be more fluffy and airy. This only addresses the question about the (important) consistency though, but I guess you should just try it out yourself.

Edit:

Some benefits of using sparkling water in the kitchen

As this answer got downvoted to zero I guess my grandma was not convincing enough. So I asked a befriended chef who works at a luxury hotel chain in Germany. Here's what he explained:

  • Desserts can be made more creamy without actually adding cream. Here he gave examples of pudding/mousse-ish desserts
  • Vegetables steamed with sparkling water results in less loss of color (i.e. brighter colors), more crispyness, and stronger taste. He particularly recommended to try it with carrots, broccoli or cauliflower.
  • You can add sparkling water to thick soups shortly before serving to get them more foamy.
  • Similar with Salad dressings
  • Last but not least he confirmed precisely what my grandma said. For doughs and similar stuff (for salty or sweet dishes) you would get a nice fluffy texture. Kudos to my grandma at this point.

    But why? It is utterly counter-intuitive that there would be any different results. I appreciate that you found two anecdotal references for this but a scientific explanation would be more useful. – Catija Nov 16 '15 at 14:57

    Some things might have to do with pH - the CO2, while bound in water, forms an acid. Doesn't explain less loss of color though... acids usually make color loss worse. – rackandboneman Jun 13 '16 at 12:22
  • I read this as a very plausible guess and opinion. It's not an answer. – CAgrippa Jul 23 at 6:03

i have a book called @Baking With Passion' by Dan Lepard and Richard Whittington, (Dan L runs some very classy bakeries in London and is a highly respected baker I believe). In there it says 'We prefer to use bottled still spring water. This does not rule out the use of tap water, but bottled water is less likely to contain chlorine or other chemicals which might well impede yeast activity.' I use ordinary tap water that has been boiled, adjusted to the right temperature with cold water straight from the tap. I agree with Catja's reply above and I wouldn't think there could be any air left from the bubbles once the bread has been mixed, kneaded, proved, and pummelled again.

Re: Sparkling water.

It doesn't go flat as quickly as you think. The mineral water has a lot of dissolved calcium (french or italian brands) and thus the CO2 binds to the CaCO3 and it takes a while for the bonds to break. You can leave the stuff uncapped overnight and find it still fizzy in the morning. The same can't be said for soft drinks. They are called soft drinks, because the distilled water has no minerals. (Actually, I made that last line up - but its true!)

Something I learned in fish keeping and live aquatic plant care.

    No, but its still an amusing anecdote. – NightFlight Sep 11 '17 at 21:58
