When I lived in Italy I used to have bread from a company called Mulino Bianco. Here is a link to one of their bread's ingredients: https://www.mulinobianco.it/pan-bauletto-integrale?yxpt-from=search
The ingredients are just your regular bread's ingredient (wheat, water, salt, yeast, oil). but they said they add alcohol to the surface after making bread (as preservative I believe).
Would this make the bread haram?
