Brands on the page: Oatly, Califia Farms

Opened the site's own oat milk search page, titled 'Oat Milk Delivery or Pickup Near Me | Instacart', which lists Oatly Oatmilk, Oatly Barista Edition Oatmilk, Oatly Full Fat Oatmilk and Califia Farms Extra Creamy Oat Milk. The results are not tied to a District address, so which local shops fulfil them was not confirmed.

MOM's Organic Market

Ivy City and Van Ness Stock not confirmed

Opened the chain's own Washington DC page, which lists two District branches, Ivy City and Van Ness, and whose store-location list names 'Ivy City, DC' and 'Van Ness, Washington, DC'. A deliberately fake path on the same host returns a 'Page not found' title, so this page is real. The page names no products, so stock of plant milk was not confirmed.

Oatly

nationwide Stock seen on the page

Brands on the page: Oatly

Opened the brand's own US chilled oatmilk category page and its Barista Edition 64 oz product page, which loads with the product name and a full ingredient list. The site is the US arm of the brand and names no city, so District availability rests on retail stockists rather than direct delivery.

Opened the brand's own MALK Plant-Based Milks collection page and read the same collection through /collections/malk-plant-based-milks/products.json, which lists Unsweetened Almond Milk, Vanilla Almond Milk, Chocolate Almond Milk, Unsweetened Soy Milk and Original Oat Milk. None of those product records carries an ingredient list.

Califia Farms

Brands on the page: Califia Farms

Opened the brand's own products page, whose served HTML names Almondmilk, Oat Barista and Unsweetened lines. The page renders its catalogue in JavaScript, so individual products and any ingredient panel could not be read, and the site names no city.
