Cask: Unfiltered; Keg and can: Unpasteurised India Pale Ale A 5.6% west coast IPA: golden, immensely hoppy and alive with grapefruit, peach and mango flavours. Soundwave carries her drinker to the west coast, to the golden shores of California where craft ale is nectar. She is the driest of Siren’s ales – full with flavour but subtle with bitterness. Her resinous finish will pull you off balance.
