Just bought a sixer of NN - excited to dive in. But I noticed something odd - on all six bottles, the bottled date appears to be rubbed off. I can easily read the batch (130103), but the date itself is extremely hard to read. In the end, I'm not too worried because it can only be so old, but I just wanted see what others thought of this. On a side note, I also got a growler of Sucks - going to be a good weekend.
