You know your crowd best, so Sam Light might be a better option than Corona/Yeungling/Rolling Rock/Miller Lite, although for general purposes I'd typically pick something like a ML that I know everyone would drink.
Brooklyn Lager is a very good option imo. Ommegang has some good beers and is local, but they might be a little much (especially given the quantity I might drink at a wedding).
DFH 60 is a fantastic choice (AA
), but it's marginally pricier and caters more to IPA drinkers and beer aficionados. Sierra Nevada is a very good choice also, and it's more general purpose in the sense that I'd guess that a random sampling of Americans would prefer SN to DFH.
Basically, I think your list of Sam Light, SN, and Brooklyn Lager is a great list for a wedding. And if it's you getting married (I assume), mazel tov.
