Consistency in your product is crucial in the food and beverage industry, because a buyer needs to know what they're getting. If you've already successfully sold them on your product, the repeat sale is only going to happen if they can be assured they're going to get the same thing they liked the first time. Nobody in the industry understands the importance of consistency better than Anheuser-Busch. McDonald's is right there with them on understanding this. Food and beverages are products like anything else, and just like with any product, once you achieve product-market fit, it's important not to make changes that would eliminate or chip away at the fit you have with your customer base.
The linked[1] article below also highlights that "quality light beers are incredibly difficult to brew". So here you have Budweiser/AB excelling on two fronts: a difficult brew and incredible consistency.

is there a similar tradeoff in brewing? I do notice fairly obvious differences batch-to-batch in microbrews, but I would still prefer the worst batches of my favorite local beers to any AB product I can think of. are they trading away best/average taste for consistency, or is it more a function of the price point (microbrews being quite a bit more expensive)?
The version I'd heard was people associate the ashy taste and dark roast with higher caffeine, even though it's the opposite.
