So, is it worth it? Well, in terms of DLC, the Ale Pack
has the least features of any DLC that I can remember. However, it costs just under a dollar on Steam and I saw it on sale over the holidays for half off... less than 50 cents.
I hate games that nickel and dime you to death, but there was some free DLC made available over the holidays and there are other ways to make your dwarves happy, if you keep your Crafter busy. So, given that it's not required to play the game and that it's so inexpensive, I recommend the Ale Pack for anyone who would rather simply grow happiness as a crop or cash in 300 wood to tap some good times.
