The delicious details

Fort Negen brings a craft-first approach to bread and pastry in Amsterdam West. Founded by Maarten Langeslag after years baking at Restaurant De Kas, the bakery centres on a 26-hour sourdough fermentation and organic stone-milled grains sourced from Dutch and French farmers working with regenerative methods. Everything is baked in full view behind a glass facade, with production running throughout the day.

The adjacent sandwich bar on Jan Evertsenstraat turns house breads into composed sandwiches featuring fermented vegetables, smoked meats and condiments, all prepared in house. The menu shifts with the seasons, and weekend specials draw queues of locals for inventive cruffins, patisserie and savoury pastries.

Fort Negen also runs baking workshops and an academy, and has published a recipe book covering over 200 recipes from its bakery and kitchen.

Menu
What's on the table, and what's left off

The kitchen revolves around grain and fermentation. Sourdough breads proof for 26 hours using organic stone-milled flour; pastries use the same whole-ingredient approach. The sandwich bar pairs house breads with fermented vegetables, house-smoked meats and house-made condiments. Long fermentation and stone-milling are chosen for flavour, digestibility and nutrient retention.

Vouched

Fort Negen demonstrates specific health-intentional practices in ingredient processing and integrity. The 26-hour sourdough fermentation is linked to good digestibility, and locally stone-milled grains preserve more nutrients than industrial milling. Whole grains are the foundation of the product range.

Local and direct sourcing is central to the operation: organic grains come from Dutch and French farmers working with regenerative methods, processed through local stone-milling, and the sandwich bar works with local suppliers for its seasonal ingredients. The menu follows seasonal availability, with the sandwich bar offering a rotating selection and the bakery introducing seasonal patisserie and weekend specials throughout the year.

Low-waste practices are built into the operation: all condiments, fermented vegetables and smoked meats are prepared in house, and leftover bread is converted into miso rather than discarded.

Grains from Dutch and French regenerative farmers, processed via local stone-milling and used throughout the kitchen.

Fort Negen sources its primary ingredient category (grains) from Dutch and French farmers practising regenerative agriculture. The breads, pastries and sandwich bar all centre on these grains, processed through local stone-milling. This sourcing is confirmed by the independent Van Amsterdamse Bodem platform as part of a transparent food chain.

The sandwich bar works with local suppliers for seasonal ingredients. Individual farm or supplier names are not published, and sourcing detail for other key categories (dairy, meats, fruits) is not evidenced. Estimated 30–50% of key categories show local or regional origin.

Menu rotates seasonally; sandwich bar changes regularly, bakery offers quarterly patisserie updates and weekly weekend specials.

The sandwich bar menu 'changes regularly and follows the seasons' with ingredients that 'vary with the season'. The bakery introduces seasonal patisserie and weekly rotating weekend specials featuring seasonal fruit and other seasonal ingredients.

The seasonal rotation appears at least quarterly, and the weekly weekend specials suggest a more frequent cycle. Editorial sources confirm the weekend specials draw customers for inventive seasonal offerings.

Leftover bread is converted into miso; condiments, fermented vegetables and smoked meats are prepared in house.

Fort Negen operates a zero-waste approach in its kitchen: leftover bread is converted into miso, and all condiments, fermented vegetables and smoked meats are prepared in house, eliminating packaging from pre-processed inputs. The bakery bakes throughout the day to minimise unsold product.

Fermentation and preservation techniques (pickling, smoking, fermenting) serve as both culinary methods and integral waste-reduction tools.

Baking academy, workshops and a published recipe book (200+ recipes) provide community knowledge-sharing.

Fort Negen engages the community through baking workshops and a Fort Negen Academy, and has published a recipe book covering over 200 recipes from its bakery and kitchen. These provide access to craft knowledge and technique.

The workshops and academy are commercial offerings rather than a formally named social-impact programme or charitable partnership. No employment initiatives, apprenticeships or community projects beyond the commercial educational offerings were identified.

Bakery's core offering of sourdough, croissants and pastries is plant-dominant; sandwich bar includes meat but vegetarian options available.

The bakery's core offering is inherently plant-dominant: sourdough breads, croissants, pastries and viennoiserie built around grains, butter, fruit and seasonal produce. The patisserie emphasises 'grains and fruit as primary ingredients'.

The sandwich bar, however, includes smoked meats alongside fermented vegetables and is not positioned as plant-forward. Vegetarian options are available. Estimated 30–50% of the combined bakery-and-sandwich-bar offering is vegetarian or vegetable-centred.

How we score
The My Treats impact scale

Every restaurant is assessed against SEERO, our six-dimension sustainability framework — covering sourcing, seasonality, waste, animal products, social impact, and plant-forward cooking. Each finding is weighted by how strongly it is corroborated. The combined result is translated into a planet rating from 1 to 5.

The five levels

SEERO is an acronym for Starting, Engaged, Endorsed, Recognised, Outstanding:

Starting First verified signals of sustainable practice.
Engaged Credible practice across two dimensions.
Endorsed Meaningful practice across three or more dimensions.
This place
Recognised Strong practice across four or more dimensions, with independent corroboration.
Outstanding Top-tier practice, confirmed by recognised third-party audit.

How a level is reached. Each level needs two things together: a minimum number of dimensions covered, and a minimum overall strength of evidence across them. A dimension only counts once its evidence is specific and substantiated — a passing mention doesn't qualify. Meeting only one of the two keeps a restaurant a level lower.

Ratings of four or five planets require human validation and, at the top tier, an external audit. Scores are based on publicly available evidence and restaurant submissions at the time of assessment.
