This all depends on the time of year. Potatoes, like all crops are on an annual cycle, harvested from July to October. We use potatoes straight off the fields and into our factories during this period, and we put them into potato stores for the period November through to the following June until the next harvest. Our closest farms are less than 30 minutes from our factories, so during harvest time the potatoes can be turned into crisps in packets within an hour, and on shelves in supermarkets within a day or two. At the other end of the scale, during May or June, the potatoes will have been tucked up in a potato store for seven or eight months before being turned into crisps
