Prisma is a Finnish supermarket chain whose service pledge is “Affordable but good.” It is well known that Prisma is affordable. In 2015 we created a new concept to brighten the image of their range of products. It presented a whole new sport: blind testing. The uncontested champion of the sport is Pekka Makkonen. In 2016 Makkonen received a challenger from Japan. The secret weapon of both of these masters of taste is Prisma.
