We make germ bread from organic grains. Sometimes the grains are harder, sometimes softer. The type of grain mainly determines how much water it can absorb during the germination process. Spelt, for example, absorbs less water than rye and wheat. In addition, the weather plays a major role. Some crops will always germinate better than others. We always try to produce as consistently as possible, but there will always be differences. If your sandwich is really too hard, please contact us via the contact form.
