No mention of this whisky in the Whisky section of the Glenfarclas website. However, there is (was) a news entry, extracted as follows:

"One of the most common questions whisky fans ask is “How long has Glenfarclas been around for?”

The answer is – we genuinely don’t know. We have a painting showing whisky production from 1791, but there is no evidence of a licensed distillery here at that time – and it’s clear from the painting that they had already been producing uisge beatha for some time.
That being said, you can’t really celebrate an inexact date, so we choose instead to mark the first official licence that the distillery was awarded, and this happened in May 1836. Although some would argue we shouldn’t be celebrating when our whisky was first taxed!

To mark the occasion, Callum Fraser (Distillery Manager) and Douglas Belford (Managing Director) were given the enviable task of going out in to the warehouses to hunt for casks from across the decades that they felt best represented our 185 year history. This was a long process, but after almost 2 years of adding a few casks at a time, they are more than delighted with the final result. This well layered dram with a phenomenal finish showcases the true Glenfarclas character. It was bottled at 46% and will be available soon from specialist whisky shops via our network of international distributors."
