Which stock has Warren Buffett bought more than any other in recent years? That's an easy question. The answer is clearly Berkshire Hathaway. The conglomerate has spent billions of dollars on stock buybacks initiated by Buffett.

Constellation Brands (NYSE: STZ) seems like a classic Warren Buffett buy. It has well-known brands with staying power and solid long-term demand, and the recent panic selling of the stock is a great time for some opportunistic buying.

Warren Buffett is known for buying stocks when they're undervalued -- and then scoring a win after the rest of the market realizes the strengths of these particular players. This is the case with his investment in one of today's most well-known companies.
