You can have a different name for each bottle!
I use the mailing labels from avery that come 30/sheet to label all my bottled beer plus different colored caps for each version. I brew porters and stouts and often have up to four different versions per batch by adding extracts or adjuncts either directly to the bottle or sequentially to the bottling bucket as I go along.
And many times, I have different versions left in the garage fridge from a previous batch with multiple versions.
The labels help me keep it straight, especially at brew club meetings where I've sampled over-hopped IPAs and some one asks me what's in my bottle that they have just sampled. With my taste-buds loaded with too much citra or similar hops the labels are a godsend.
