It's not all about the recipe. Is it?
I'm drinking a beer. I have drank this beer many times. It's a fridge regular at Scoop Towers. It's available in supermarkets and chain restaurants. Which is why I drink it often.
Until sixty seconds ago, I had no idea what exactly went into it. I could guess.
But, you know what? To me, it doesn't matter.
I now know it's full of two-row, Hallertauer Mittelfrueh, Vanguard and Cascade. 33 IBU. 170 kcal.
Big diff. It tasted great before that knowledge; it tastes the same great right now.
Some beers are defined by an obvious malt bill, hop addition or yeast strain. It's good to know in those cases; you like the effect, you can find more beers that express themselves in a similar way. Or run an avoidance play on them.
For the rest; does it really matter?
Wouldn't you rather have the mystery?
