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.
As a result, a nucleus will attract electrons. These electrons will swarm around the nucleus, and the result is an atom. Now we haven't explained everything yet. The electric force explains how the electrons are bound to the nucleus of an atom. But we haven't said anything about what holds the nucleus together. The electric force can't account for this, and in fact, the electric force actually works against holding the nucleus together.
