AB egg nog newbie

I just made a batch of the AB egg nog, courtesy of a post I saw here a few weeks ago and all the endorsements.

I feel like I followed the recipe which is simple enough, however it seems thinner than typical egg nogs I’m used to (store bought pre-made stuff).

Question for the seasoned egg nog veterans out there…. Is the thinner consistency normal, or did I mess something up (e.g. too much booze)?

Perhaps it thickens over time?

Or maybe all the store bought stuff is wrong and good egg nog isn’t supposed to be really thick…
