From our delicate, sweet, crisp button come all the varieties in between: our standard closed cup, open cup (more flavour, adding a deeper rich colour to cooking), our large white closed cup which we aptly named the Greeba Giant (grown for longer and kept tightly closed to give fuller flavour and wonderfully crisp too). After this stage we allow them to open up into breakfast flats, or flat chestnuts in the brown variety, then stuffing mushrooms and portabello.

The most mature of all is the portabello. With a rich intense flavour and meatier texture it is by far the most flavoursome. From the button stage it will take around a further five days to grow into a portabello. Contrary to popular belief the more mature mushrooms, when fresh, are by no means woody and they are a great alternative to meat both for flavour and nutritionally.
