June 4 (Reuters) - Whiskey maker Brown-Forman BFb.N beat Wall Street estimates for fourth-quarter net sales on Thursday, helped by steady demand for its premium brands, including Jack Daniel's whiskey, especially among affluent consumers.

The company posted sales of $912 million, beating the average of analysts' estimates of $879.6 million, according to data compiled by LSEG.

This was the first quarterly report by Brown-Forman since the company rejected a roughly $15 billion approach from Sazerac and the collapse of separate merger discussions with France's Pernod Ricard PERP.PA.
