I'm pretty sure the UK is one of the only places in the world which doesn't stock any Red Stripe stubby bottles. Well thankfully that's all changing. Red Stripe are now shipping over their traditional short neck, flat form and large base bottles to our shores.
The new 300ml bottle is currently available at pubs, clubs and bars throughout the United Kingdom (especially in Shoreditch too I'm guessing). From next Summer you'll be able to pick them up in the shops. We've still got a year to wait, so add the date to your diary so you don't forget.
