From the Valhalla Brewery in Unst, comes this light, golden bitter ale. Its name comes from the Shetland dialect words for that hauntingly beautiful twilight time at midsummer when darkness never descends on these isles - the sun sets, only to rise again just minutes later.

Simmer Dim was launched in April 2000, at the annual Shetland Folk Festival and temporarily named 'Festival 2000' for that event, but was later named Simmer Dim. It has an ABV of 4.0% and is a light golden bitter.
