The good, the bad and the average

Marks & Spencer raspberry & bio yoghurt

250ml: £1.30, 500ml: £1.99

Very fruity and punchy. Perfect if you don't like very creamy drinks

Innocent mangoes and passion fruit

250ml: £1.69, 750ml: £3.49

Quite pleasant and has a good texture. It has strong flavours and good balance of sweetness

What’s Average

Sainsbury's strawberry yoghurt smoothie

250ml: 95p

Not unpleasant but not outstanding either

Safeway The Best strawberry bio yoghurt smoothie

250ml: 99p

Quite nice but the yoghurt flavour is too strong

What’s Bad

Pret A Manger mango with banana smoothie

250ml: £1.85p

An assault on the taste buds, acidic

PJ oranges, mangoes and bananas

250ml: £1.39p

Too thin, very watery and just not fruity enough
