The 18 year old expression still carries the “small batch” moniker as it is produced from around 150 casks at a time.
Bottled at 40% ABV the single malt is chill filtered and reportedly has colouring to maintain consistency across batches. The bottles are produced in batches and so can be sold out occasionally, but when you do find one, they currently retail around £100 GBP for a full sized bottle.
