Sourdough-flavour shoppers
You want a tortilla made with sourdough, but the ingredient alone does not tell you whether the dough underwent an artisan or long-fermentation process.
Who is choosing?
Fibre-focused shoppers
You care more about the stated fibre content than a sourdough name and want to compare figures using the same weight or serving basis.
Gluten-avoiding shoppers
You need an explicitly gluten-free wrap. The identified Mission sourdough tortilla contains wheat and rye, so it does not meet that requirement.
What should you check?
Settle any ingredient or gluten requirements first, then compare fibre figures and choose a pack size you can use as instructed.
| Priority | What to check | Your needs |
|---|---|---|
| Sourdough ingredient | Tesco and Mission list 2.6% inactive rye sourdough in Mission’s four-pack. Check the ingredients rather than treating “sourdough” as evidence of a particular fermentation method. | I want a tortilla made with sourdough, but I would need separate information if the production method itself matters to me. |
| Fibre | Tesco lists 1.2 g per approximately 61 g Mission wrap. Sainsbury’s lists 6.1 g per wholemeal tortilla cooked as instructed; M&S lists 8.3 g per 100 g of its seeded wraps. Put figures on a comparable basis before drawing a conclusion. | Fibre content matters more to me than a sourdough ingredient, so I want to compare the amount in the portion I will eat. |
| Gluten and allergens | Mission’s rye-sourdough wraps contain wheat and rye. The cited Old El Paso tortilla is labelled gluten-free; check the ingredients and allergen information on the particular pack. | I need a wrap explicitly labelled gluten-free, rather than assuming sourdough is suitable. |
| Pack and storage | Mission’s cited pack has four wraps and Tesco instructs use within two days of opening. Sainsbury’s cited wholemeal pack has eight; check its own storage instructions and the date on the pack. | I may eat wraps only occasionally, so I want a pack I can use within its instructions after opening. |
| Full recipe | Read the complete ingredient list alongside the sourdough or wholemeal description. Neither description, by itself, establishes how a wrap is classified or assesses its quality. | I want to judge the actual recipe. In the Food Standards Agency and YouGov’s June 2026 survey of 2,197 respondents in England, Wales and Northern Ireland, 78% expressed concern about ultra-processed food and 76% about food quality when prompted. Those separate, potentially overlapping concerns do not assess these wraps. |
What is easy to overlook?
-
Assuming sourdough means long-fermented or gluten-free
Mission’s identified wrap lists 2.6% inactive rye sourdough and contains wheat. Its sourdough ingredient does not establish a particular fermentation method or gluten-free suitability.
Decide whether you want that ingredient, information about the production method or an explicitly gluten-free tortilla; check for the requirement that matters to you.
-
Comparing fibre numbers from different portions
The cited figures refer to an approximately 61 g Mission wrap, a Sainsbury’s tortilla cooked as instructed and 100 g of M&S seeded wraps.
Compare the same weight, or account for the portion you expect to eat, before using the figures to choose.
-
Choosing a pack without planning when to use it
Tesco instructs shoppers to use Mission’s four-pack within two days of opening. The cited Sainsbury’s wholemeal alternative contains eight wraps.
Consider how many you will eat after opening and follow the storage and date instructions on the pack you buy.
Relevant brand references
Mission
Mission’s identified four-pack is a wheat tortilla made with rye sourdough.
- Mission and Tesco list 2.6% inactive rye sourdough.
- The wrap contains wheat and rye; the ingredient listing does not establish an artisan or long-fermentation process.
Sainsbury’s
Its cited eight-pack is a wholemeal wheat tortilla alternative, not a sourdough tortilla.
- Sainsbury’s lists 6.1 g fibre per tortilla on its stated cooked basis.
- Check the serving basis before comparing that figure with another wrap’s per-100 g value.
M&S
Its cited seeded tortilla is another option when the ingredient mix and stated fibre content matter more than a sourdough name.
- M&S lists 8.3 g fibre per 100 g and mixed seeds at 2.5%.
- The ingredient list includes dried fermented wheatflour, but M&S does not identify this product as a sourdough tortilla.
Old El Paso
Its cited gluten-free tortillas offer a different route for shoppers who need to avoid gluten.
- The cited six-pack is labelled gluten-free and lists tapioca starch and white corn masa flour.
- It is not a sourdough tortilla; check the particular pack’s ingredients and allergen information.
A gluten-free tortilla option on Joybuy
This Old El Paso wrap is an explicitly gluten-free alternative for someone whose requirement rules out the Mission sourdough tortilla. It does not meet a sourdough preference.

Questions about choosing and keeping wraps
Are Mission’s sourdough wraps gluten-free?
No. The identified Mission tortillas contain wheat and rye. If you need to avoid gluten, look for an explicitly gluten-free wrap and check the ingredients and labelling on the pack you receive.
Do the Mission sourdough wraps need warming?
The cited pack gives warming instructions rather than making warming a requirement: Asda lists dry-frying for 10–15 seconds per side and also gives microwave instructions. Follow the directions on your pack.
How long can I keep an opened pack?
Tesco’s listing says to re-close the identified Mission pack at the seam and use it within two days of opening. Other wraps can have different instructions, so follow the storage and date information on the pack you buy.
What should I check when ordering wraps for someone with an allergy?
Check the exact product’s ingredient and allergen information before ordering, then read the label on the pack received. A sourdough description is not an allergen-safety claim: the identified Mission wrap contains wheat and rye.
