Quaker plans to build on the success of its Oat So Simple range with the launch of two larger-serve lines and two new flavours.

This month, its Original and Golden Syrup varieties will launch in ‘Big Bowl’ sachets, which are 33% larger than the standard format (rsp: £2.29).

It is also adding strawberry, raspberry & cranberry, and vanilla & honey flavours to the range and introducing Oat So Simple Strawberry to the children’s portfolio (rsp: £2.29/10-sachets).

The activity will be supported by a TV push from November, and follows strong sales for the brand, which has grown £10m in the past five months to £80m [Nielsen 52 w/e 7 July 2012].
