Verdant say:

We’ve blended zesty lemonade with our beloved Extra Pale Ale Lightbulb, chocked full of lemon sherbet hops. At just 2.4%, RADBULB dials up the citrus, spritz, and sessionability with a pale ale backbone. Packed with a light malt character and gentle hoppy bitterness it’s juicy, tangy, sharp, and brilliantly balanced. And if you ask around the brewery, some would say it tastes just like a ramped-up version of San Pellegrino’s fancy Limonata. Absolutely delish!
