From the brewery:

In our latest Duck Series release, we’ve gone big. Eider the UK’s largest water bird is the name of our 8% Double IPA. Lush mouthfeel and juicy saturation, with just a touch of dryness for drinkability. Dry hopped with Idaho 7, Nelson Sauvin, Citra and Mosaic hops layer in sticky stone fruit, bright citrus and dank tropical notes. Eider joins the flock alongside siblings Teal and Mallard – landing with weight, swagger and surprising grace.
