The number of households buying alcohol is dropping according to TNS Superpanel. But those consumers in the market are increasing the amount they buy. The average household is spending £107.80 a year (up from £101.80 last year) on wine and £83.70 on beer (up from £75.90). Scottish Courage commercial director Sandy Corstorphine said: "Beer buyers' spend is increasing because of the switch to multipacks, not because the prices went up, as there is deflation in the market." The number of households buying wine has also declined. Both beer and wine have suffered from competition from premium packaged spirits. It has attracted more buyers and the average annual weight of purchase has gone up to £18.40 from £14.50. Corstorphine said: "Beer buyers are buying across the total alcohol category. The penetration of premium lager is up and the increasing weight of purchase is being driven by 24 packs." The TNS Superpanel measures the shopping behaviour within multiple grocers and co-ops of 15,000 households. It compared the year to the beginning of March with the previous 12 months. {{DRINKS }}
