Predictably there has been outcry about this. Everyone associates Bond with Martinis (not unjustly) but he is more than a one hit wonder when it comes to drinks. Bond will drink most things if the situation requires it. Throughout the books, Bond has been known to enjoy a beer; usually with Leiter or when in a hot climate. He has also been seen to drink beer in the films; the bar scene in Licence to Kill or before he escapes from the CIA in Quantum of Solace to name but two. The precedent is well and truly set.
Overlooking historical references to Bond, let's not forget that Bond has been a vehicle for product placement since it began. This started as Ian Flemming's love of the finer things in life and has evolved into a slightly more blatant process. Companies can and do pay vast sums of money for their products to feature in a Bond film. That does not mean that any one product takes over a given film - apart from the obvious ones.
Think of the Omega watches in the most recent two films. Apart from a rather clunky reference on the train scene, the watches so far have been visible only if one is looking for them. The Rolexes in several other films have been little other than cameos yet I'm willing to bet each firm paid handsomely to feature. This phenomenon is not limited to watches. Smirnoff vodka featured for only a few seconds in Goldeneye and certainly did not detract from the plot.
Let's bring these two strands together: Bond as a character has a history of drinking a variety of drinks according to the circumstances. Not only that but Bond as a franchise has always been a hotbed of intentional and unintentional product placement. Thusfar it has been managed reasonably discreetly and without detracting from the plot.
Finally let's bear in mind one other very important fact. The Bond producers are not stupid. Barbara Broccoli grew up with Bond having had Cubbi as a father. If Fleming was a father to Bond then Cubbi was certainly an influential uncle. The upshot is, they know how to make a Bond film. They know that a dinner suit is expected, as is a martini and the line, "Bond. James Bond!" And they know it would be professional suicide to deviate too far from this formula. Bond may well sup a beer but I am confident it will in now way spoil what is shaping up to be a good film.
