Overview
Hemp seeds (hanfsamen) are small, oil-rich seeds with a mild, nutty flavor and soft texture that tolerate sourdough fermentation well. They add healthy fats, protein, and a subtle nuttiness without overwhelming the crumb. Use them as whole seeds or lightly crushed for more flavor release. Their high oil content means they won't absorb water like whole cereals, so treat hydration differently than you would for nuts or whole grains [1][2].

How to use in dough
Timing: Add hemp seeds during bulk fermentation folds or at the final mix to distribute them without overworking the dough. For even distribution, sprinkle seeds over the dough and perform 3–4 sets of coil folds, or incorporate them after an initial 20–30 minute rest so gluten has begun to develop and seeds won’t interfere with structure [1]. If you prefer a concentrated layer, fold them in during shaping. Tools: Gently fold with a dough scraper and use a large mixing bowl for bulk handling. When handling starters or seed hydration, measure with a Digital Kitchen Scale for repeatable results [1][2].
Measurements & hydration
Typical inclusion rates: 5–15% of total flour weight (baker's percentage). For example, in a 500 g flour recipe, use 25–75 g hemp seeds. Because hemp seeds are oily and do not absorb as much water as flour, do not increase dough hydration by the full weight of the seeds. Start with adding 0–25 g extra water per 100 g seeds and adjust based on feel—if dough feels slack add more; if tight, reduce [1][2]. Always weigh seeds on a Digital Kitchen Scale for accuracy.
Soaking & toasting
Soaking: Soaking is optional. A short soak (20–60 minutes) in equal-weight water softens seeds and can reduce their tendency to draw moisture from the crumb during storage. For better integration and slightly milder flavor, soak seeds in warm water or a portion of your dough water. Toasting: Lightly toast seeds in a dry pan until fragrant (1–3 minutes) to increase aroma and crunch; cool completely before adding to the dough. Avoid heavy toasting that increases oil release which can coat gluten and reduce oven spring [1][2].
Flavor and Texture
Hemp seeds impart a mild, green-nutty flavor that complements whole-grain and rye sourdoughs. Whole seeds create small pockets of oil and a soft bite; crushed seeds increase surface area and release more aroma but can slightly tenderize crumb due to released oils. Balance the percentage depending on whether you want subtle background flavor or a noticeable nutty character [1][2].
Baking Tips
- Add seeds near the end of mixing/bulk to avoid gluten weakening from oils.
- If using a high percentage (>10%), reduce added water slightly or compensate with 5–25 g extra water per 100 g seeds, checking dough feel.
- For even shaping and proofing, use a banneton proofing basket and line with a lightly floured linen or use parchment paper for transfer.
- For clean scoring, use a bread lame/Scoring Tool.
- Bake in a Dutch oven or cast iron pot when possible to preserve steam and maximize oven spring.
- Store finished loaves wrapped in cloth at room temperature for 2–3 days or slice and freeze for longer storage [1][2].
Summary
Hemp seeds are an easy, low-impact add-in that bring nutrition and mild flavor. Use 5–15% of flour weight, consider a brief soak or light toast, and add late in the process to protect gluten. Accurate weighing with a Digital Kitchen Scale and gentle folding with a dough scraper will give the most consistent results [1][2].
