This is weird. Did you know you have to be 21 years old to LOOK at beer on the internet? As part of my search for pictures to use in my Friday Beer Blogging (TM), I started running into pages either asking me if I am 21 or to enter my birth date. Here's an example. I went to a wine site and didn't see the same restriction. However, I noticed I could order their wine online and it never asked my age.
So let's recap. You can't LOOK at beer online if you are under 21 but you can BUY wine at any age.
