ARNAUDVILLE, La. — There is plenty to drink to these days here in the bayou country of southern Louisiana, where the flat farmland is already tinged green with sugar cane and rice. There are the first fat crawfish, a blush of pink on the swamp maples and Mardi Gras at the end of the month.

Arnaudville, a rural town northeast of Lafayette with just 1,000 residents, falls in the center of Acadiana, a hot, humid region that takes its name from the 18th-century French colony of Acadia in eastern Canada, whose people made their way to this swampy, Spanish moss-draped land after they were expelled by the British. The laws here follow Napoleonic Code, the gas stations stock good bread and the culture is still so Cajun — short for Acadian — that residents speak French and teach their kids to play the accordion.

All of this might explain how a small family brewery on a former corn and bean farm here produces some of the most distinctive craft beers in the United States, with flavors that could only come from Cajun Country.

Run by Karlos Knott, 53, whose paternal ancestors arrived here in 1780 from Quebec, Bayou Teche Brewing is an eight-year-old family-owned operation, situated on a piece of property that includes the four Knott family houses, a crawfish pond and a dance hall known as the Turnip.
