I've been examining bottle codes for VW and BTAC bourbons for a while now and I've recently seen discussion on the topic from SKU and others. The key information seems to be the day and year in the middle of the code. However I have become ever more curious about the letter code for the bottling lie. I've seen J and K the most. I also believe I've seen L and N too.

Can anyone provide some insight to how many bottling lines are at Buffalo Trace, their associated code and where they are located on property?
