In the following video, Motley Fool analyst Matt Koppenheffer tells us about Warren Buffett's enormous new purchase. Berkshire Hathaway (BRK.B 0.23%) has announced that it's teaming up with 3G Capital to buy H.J. Heinz (HNZ) for a total price of $28 billion. The deal is right in Buffett's wheelhouse, as he's known for having a soft spot for companies with great, well-known brands. 3G brought the deal to Buffett, and it will oversee the company after the acquisition.
