#HBBAdvent Beer 5: Siren Craft Brew/Garage Project Blacklight Banana Imperial Stout (Finchamstead/New Zealand)

Siren/Garage Project says: For this year’s Rainbow Project collaboration with Garage Project we drew the colour indigo. After much research on both sides the idea that excited us all most was that of the Blacklight Banana. Ripe bananas uniquely glow bright indigo under UV lights, one possible reason for this being that it identifies them as a food source for animals that see in the UV range, like bats. Molasses, caramelised bananas, banana purée and bourbon barrel aged coffee beans elevate this beer to something special.

We say: We always look forward to Rainbow Day, where the collaborative efforts of the seven participating UK breweries and their international counterparts are released. The 2016 project had special interest to us as it featured seven (or six, as it transpired this year) New Zealand breweries, including Garage Project, probably the most hyped Kiwi brewery never to make it to UK shelves. Jos and his team are doing exceptional things in the Aro Valley, as we discovered during an infamous 22-beer tasting session when we were back in January, and we can't wait until they decide to export over here. In the meantime, this lush impy stout, brewed with Siren, helps to ease the pain of Garage Project's absence. And who said you can't drink a 9.2% stout on a Monday? You've earned this. - Jen
