Why does Samuel Adams beer have a number under the bottle cap?

The number under the Samuel Adams bottle cap is actually a unique batch code. It's not just a random number; it's a specific identifier for that particular batch of beer.

Here's why they use a batch code:

* Traceability: If there is ever a quality issue with a specific batch, the code allows Samuel Adams to quickly identify and isolate the problem. They can trace the issue back to the specific ingredients, production date, and equipment used to make that batch.

* Inventory Management: The code helps Samuel Adams track their inventory and manage distribution efficiently. They can use the code to see where specific batches are located and how much is available.

* Customer Service: If a customer has a concern about a specific bottle of beer, they can provide the batch code to Samuel Adams for assistance. This helps them investigate the issue more effectively.

While the number itself might not mean much to the average consumer, it plays a vital role in ensuring the quality and safety of Samuel Adams beer.
