Explore the current selection
The OSULLOC collection shows the products currently available in our catalogue. Pack sizes and recipes vary, so a familiar name is a starting point rather than a complete description.
Leaf tea and bags
If you enjoy measuring a pot, explore loose-leaf tea. For a portion already measured, compare tea bags and pyramids. Check net weight as well as the number of units; the shape of a bag does not by itself establish leaf quality.
For a simpler ingredient list, begin with the green tea selection and read the composition of the specific tea.
Blends and powdered drinks
A flavour name describes only part of a blend. Read the ingredients to see whether it contains tea leaves, fruit, herbs, flavourings or other ingredients. Use product-specific information when checking caffeine or allergens.
In the powdered tea collection, distinguish tea powder from drink mixes containing other ingredients. Follow the directions for the reference you choose; one preparation method does not fit every powder.
Choosing a gift
Our tea gift sets list the assortment and pack size. Compare the number of flavours and units of each, then check the included teas and the photographs for what comes in the box. The gift guide helps you match a set to the recipient.
Preparation, ingredients and storage
Use the maker's directions for the exact pack. Water temperature, time and portion can vary between teas. Ingredients and precautionary allergen notices must also be read product by product rather than assumed for the whole brand.
Product pages identify the available source information. Check the label supplied with your product, including storage and date information, and contact us if it differs from the description.
Ordering from your destination
Available destinations and delivery information are shown during checkout. Our shipping guide explains the current charges, and the customs guide explains what to check about import charges.
