The runaway success of Archer's Aqua, the summer's major launch from Guinness UDV, has caught the company on the hop. It thought it had made enough provision, but demand is triple its forecasts. The success, although welcome, is embarrassing as it is in danger of repeating similar problems it had after the introduction of Smirnoff Ice in 1999. A spokeswoman said the company had looked at the Smirnoff Ice figures and tripled them for the forecast for Archer's Aqua. It means Aqua is selling six times the amount that Smirnoff Ice did at launch. She said: "There are some supply problems and there are allocations for our top 10 customers in the on and off-trades. We appreciate the frustrations of our customers but we hope to have things sorted out by September." {{DRINKS }}
