Bought: Tesco Supermarket, 3rd June 2019
In 2018 Tesco Supermarket here in the UK decided to stock two ‘mystery’ single malts under the name of Aerstone. These are the ‘Land Cask’ and ‘Sea Cask’. They come with an age statement of 10 years and a volume of 40%. It’s not uncommon for supermarkets to have their own single malts but usually they’re labelled ‘ASDA’s Islay Single Malt’ or ‘Sainsbury’s Speyside Single Malt’. It’s unusually for a supermarket to register a trading name for a mystery whisky (where the source distillery isn’t clearly indicated). This is all very interesting but it was the price of £20 that caught my attention (reduced from £30). This made Aerstone the cheapest 10yo single malt on the market, even when the Aberlour 10yo is on offer. And considerably cheaper than the MacPhail’s 10yo mystery malt. Tesco, you have a winner!
The Aerstone duo aren’t really mystery malts in the traditional sense. Firstly it’s common knowledge that the source distillery is Girvan, owned by William Grant & Sons. Secondly a mystery malt typically comes from an established single malt distillery and Girvan is better known for producing grain whisky. Nevertheless since 2007 the Girvan complex has incorporated the Ailsa Bay distillery, which has been releasing single malt since 2016. With the Aerstone being 10 years old it’s possible that one or both of the cask types started life as Aisla Bay, which isn’t a bad thing.
It should come as no surprise that the Land Cask is doing better than the Sea Cask in reviews because peat and smoke make it more interesting. But both malts are considered to be easy going, straightforward sippers. Yes they contain E150 colourant and 40% seems quite tame these days but at £20 you can’t expect the earth to move. Both whiskies get excellent scores from William over on the Scotch Malt Whisky website and 81/100 on Whiskybase for the Land Cask is a pretty decent mark.
Overall I’d say that Tesco’s request to William Grant & Sons to give their customers two single malts that showcase the different profiles from different areas of maturation has been a success. And you can’t grumble at the price!
