Britvic has expanded its Robinsons portfolio with 500ml bottles of double-concentrate squash.

The new packs are rolling out now in four of the brand’s no-added sugar flavours - orange, lemon, apple & blackcurrant, and summer fruits (rsp: £1.39). Each bottle provides about 20 servings, the same as a regular one-litre bottle.

The new bottle, which joins the 1.25-litre and 1.75-litre double-concentrate formats, was easier for shoppers to carry and store, said Britvic.
