Do people truly believe that there was banana in Tom's wheat beer? That is hilariously funny, but it is also disturbing that they didn't do a better job of explaining things on the show. Wheat beers typically have esters in them that form during fermentation, and banana esters (amyl acetate) are absolutely typical of this style of beer. So it is a subtle banana flavor, not actual bananas.
It's a good thing they didn't give them a saison beer full of barnyard funk, because Mr Man Bun guy would for sure have used the excuse to incorporate dirty hay into his dish again... But I digress.
By the way I tried the golden ale that Padma inspired at Stone Brewery last week and it is absolutely great. Fabulous beer with food, multi-layered, interesting. Stone did a really good job on that one.
