Aging LSM Aether in former port wine barrels as well as former Islay single malt barrels results in a profile that doesn't leave a lot of the coniferous, fresh and pepperminty original and instead introduces extra caramelized fruit and spiced wine in the nose and an initially muddled taste that becomes strongly peaty when swallowing before finishing on a more dark chocolatey coffee aftertaste with junipery hints throughout. It's pretty interesting neat but doesn't do as good a job with ice or with tonic. The batch I've sampled was number 2 with an ABV of 48.8%. This can vary between batches.
