Lagavulin is an Islay single malt. The distillery is another one that is now owned by Diageo(see earlier review of Oban) and is marketed as one of their "Classic Malts". The distillery has been around since 1816.
The whisky has an amber color and a strong peaty/iodine nose. It's taste, hosever, is round and smooth with a lingering finish. Some people may find it too strong. For example, Lisbeth Salander referred to it as something that could be used to tar a boat.
