Bottle codes

[DillyT]

I have been forgetting what the codes mean on some of the bottles I have.

Ie I have just found two unopened bottles in my to open/opened Whisky cupboard that where given to me years ago and I have forgotten what the codes mean.

They are Cadenhead cage bottling's
1st is a Springbank 12yo RB BRL bottled in 2013
2nd is a Hazelburn 10yo RB HHD also bottled in 2013

I know that RB is Refill Bourbon

But BRL and HHD I can not work out, is it something to do with the barrels?

I think the HHD may be hogshead and the BRL barrel. Certainly my current one is marked Springbank 12 FB BRL which i was told was a fresh bourbon barrel..

Thanks, I was thinking it would of been something like that..
