Yeah, "corn likker" is very popular in NC and in the South in general. Discovery channel even produces a TV show about it - "Moonshiners".
A couple of oddball notes that might interest:
Non-tax-paid distilled alcohol is really expensive (at least the good stuff is). In fact, it's considerably more expensive than legal, tax-paid liquor. Regular white lightning goes for about $80 - $100 a gallon and up, depending on the skill of the moonshiner. Fruit brandies can go for $200 a gallon or more, depending on what fruit went into it. Personally, I'd rather have properly-aged bourbon from the state store, but the sub-culture of "anti-revenooers" seems to place a monetary premium on the stuff simply because it's untaxed.
Funny thing about the culture of the Old South that frowns upon drinking of alcohol in any form: this is a relatively recent development. Until the early 20th century, drinking water was dangerous - you could get violently ill from cholera, e. coli, amebic dysentery, etc... So workmen of the day drank diluted beer or grog (grog is water with a little bit of rum or other spirits in it). This might partly explain the culture of "sweet tea" - in order to make tea, you have to boil the water, even if you're going to drink it cold.
In fact, some of the references I have describing the contracts between the shop master and apprentices/journeymen in cabinet shops of the late 18th and early 19th century specify that the workers were to be provided with several quarts of beer per day as part of their pay.
