For an Easter Sunday lunch needing at least four UK pints, plan on three 1L cartons rather than two: the pint measure stated in the Product Regulation and Metrology Act 2025 makes four pints just over 2.27L, and Tesco lists oat drinks in 1L cartons. Choose a general-use drink for cooking and table use, and consider a barista carton if frothy coffee matters. Check each carton’s allergen information and added nutrients against your guests’ requirements.
Allow for the oat drink used in recipes, served with food and poured into hot drinks. Four UK pints are just over 2.27L under the pint measure stated in the Product Regulation and Metrology Act 2025, so two 1L cartons fall short; three provide 3L.
If lattes or cappuccinos are on the menu, compare cartons marketed for foaming with general-use drinks. Oatly, Alpro and Minor Figures each describe particular barista products for coffee use; those claims do not apply to every oat drink they sell.
Read the exact carton’s allergen and suitability statements rather than relying on a plant-based description. If oat drink regularly replaces dairy in the household, the British Dietetic Association also advises checking whether added calcium is listed.
Work out the amount needed for the whole meal, then choose cartons for their intended uses and check the labels for everyone being served.
| Priority | What to check | Your needs |
|---|---|---|
| Enough oat drink | Check the volume per carton and the total you will buy. The pint measure in the Product Regulation and Metrology Act 2025 puts four UK pints at 2.273045L; three 1L cartons provide 3L, while two provide only 2L. | I need at least four UK pints across cooking, serving and drinks, so two 1L cartons will not cover the planned amount. |
| Meal and coffee use | Check the uses stated for the exact product. Sainsbury’s lists Alpro Oat Original for cooking as well as drinks; Oatly and Alpro describe their named barista products for coffee foam. Sainsbury’s warns that its own-label Oat Drink can separate in hot drinks unless the water cools slightly. | One carton type needs to cover several lunch tasks, or I want a separate barista carton for coffee after the meal. |
| Added nutrients | Read the ingredient and nutrition panels for added calcium and, if relevant, iodine. The British Dietetic Association advises checking for added calcium rather than assuming every dairy alternative contains it. | If oat drink regularly replaces dairy at home, I want to know which nutrients this particular carton lists. |
| Guest suitability | Match the exact pack’s allergen and suitability wording to each guest’s requirements. The Food Standards Agency notes that oats remain an allergen even when described as gluten-free; Marks & Spencer says its Plant Kitchen Whole Oat Drink is not suitable for coeliacs or people with milk or wheat allergy. | A plant-based label alone does not answer whether I can serve the drink to every guest. |
Two litres fall short of four UK pints, which equal 2.273045L using the pint measure stated in the Product Regulation and Metrology Act 2025.
