ELI5: How does Baileys have such a long shelf life when it's mainly made of cream ??
gpt
Alcohol! Among other things, alcohol is an excellent disinfectant so nothing can grow in there to spoil the cream.

If you leave Bailey's alone long enough, it will eventually curdle/clump, which isn't exactly spoiled but is still disgusting.
