Alcohol is a poison (for yeast as well as for people) and so the yeast is not able to grow when the alcohol content gets too high. This is why wine is never more than about 12% alcohol.
Ideally the strong nuclear force would say how the protons and neutrons are bonded together, but there is a conceptual chasm in this area. It is unclear how the residual nuclear force (at nucleus level) emerges from the strong force (at quark level), except as a general concept that the gluons leak out.
The forces that keep the atom together are 1) electromagnetic to bind the electrons to the nucleus to form an atom and 2) nuclear to hold the nucleus of the atom together despite the electromagnetic repulsion between protons. This same electromagnetic force binds atoms to each other to form molecules as well. Then the electromagnetic force yet again binds atoms or molecules to each other to form crystals (the easist solid to understand), other solids, liquids and gases.
