Hard wheat is a high-quality type of wheat that is used in making a variety of baked goods, including bread, pasta, and pastry. It is also sometimes referred to as 'durum wheat' or 'semolina wheat'. Durum wheat is a type of hard wheat that is often used in making pasta because of its high gluten content. Semolina wheat is another type of hard wheat that is mainly used in making couscous and porridge. Additionally, hard wheat is sometimes called 'spring wheat', as it is planted in the spring and harvested in the autumn. It is important to note that 'soft wheat' is the opposite of hard wheat, and is generally used for making pastries and cakes.
