Actually Dragon Stout is like the "Irish" Guinness Stout. Top fermenting Ales are from the UK, bottom fermenting Lagers are more common in Germany. I believe you were thinking of a Double Bock style lager popular in Germany.
Dragon Stout is an Irish/English style Ale
Red Stripe is a Pilsner style larger
Both beers are considered very good Caribbean Brewed Beers. However, adjuncts ( like corn or rice syrup ) are used to brew both beers.
