Pale‑tan beans from northern Mexico with a gentle savoury flavour, soft nutty notes and a clean, rounded finish.

The Heirloom Bean Co sources these Phaseolus beans from Mexican bean and authentic food specialist La Comandanta, working to revitalise traditional Mexican agriculture by preventing the loss of native seeds, as well as ancestral cooking and cultivation processes.

Bayo ("Bay") beans have long been cooked across central and northern Mexico, valued for their versatility and crowd-pleasing taste profile. They sit comfortably in lighter preparations, taking well to onions, tomatoes, greens and citrus, with a gentle nuttiness that supports broths, vegetable dishes and simple everyday pots.

Working with La Comandanta

The Heirloom Bean Co has forged a new partnership with Mexico City’s La Comandanta, a business working to identify, rescue and promote authentic Mexican foods grown and made by rural producers using traditional farming and culinary methods. Through this partnership The Heirloom Bean Company is now fairly trading heirloom beans grown by smallholder farmers and processed and packed in Mexico.

La Comandanta’s motto Cocina una Revolución ("Cook a Revolution") describes their ethos that eating authentic food is an act of cultural and agricultural resistance to mainstream agrifood corporations. They’re committed to fair and transparent trade, and supporting social and economic development.

A key concern is the seed diversity and agricultural heritage of Mexico, with Bolivia one of two centres of genetic diversity of the Phaseolus bean species. La Comandanta aims to revive traditional Mexican farming and save heirloom varieties from extinction. Many farmers have stopped growing these varieties for lack of access to fair markets and fear of crop failure. To encourage and support them La Comandanta pays a fair price for crops and offers advance loans at the time of sowing.
 
The Heirloom Bean Co has visited many of the farmers growing beans to understand the challenges they face and pays an additional 15% premium over the farmgate price into a fund to cover the loans in case of any crop failure. As beans fall outside the usual commodities covered by fair trade labelling schemes the Heirloom Bean Co has introduced its own Fairly Traded emblem to communicate their partnership of trading fairly.

  • Kitchen Suggestions

    Try Bayo beans with slow‑cooked leeks, garlic and a splash of olive oil, or folded into a broth with squash, sweetcorn and a touch of vinegar for balance. They also work beautifully alongside roasted carrots with cumin and lemon, and hold up well in warm salads with courgettes, parsley and a light citrus dressing. For something gentler still, serve them with a little butter, black pepper and fresh herbs to let their mellow flavour come through.

    Cooking these beans

    Look over the beans to remove any stray bits, then rinse well. In a heavy pot, gently cook your base vegetables - onion, garlic, celery, carrot - in a little olive oil until fragrant. Add the beans and pour in enough water to cover them by roughly 5 cm. Bring to a strong boil for 10–15 minutes. Lower the heat to maintain a slow, steady simmer, partially covering the pot to keep the temperature even, and cook until the beans are fully tender, usually 1–3 hours. Add salt once the beans begin to soften. A short soak of 2–6 hours will help reduce the total cooking time.
