So apparently reducing the size of your beer bottle by 45 milliliters and then trying to charge the same price for the beer is not such a good idea. Who knew? The folks at Australian brewer Foster’s sure didn’t. Or at least they were hoping beer drinkers wouldn’t notice. Well, they noticed. Now Foster’s is announcing they are reversing course on a plan to shrink some beer bottles. What prompted the change of heart? How about a 33 percent dip in sales. That’ll do it.
