Quick Answer
Black tea is the most common base for milk tea: its strong flavor and dark color hold up after adding creamer or fresh milk; examples include Assam, Ceylon, Ruby Black and Earl Grey. For different notes, use charcoal-roasted oolong or Tieguanyin for roasty milk tea, or jasmine green tea for a light milk green tea. When choosing milk tea leaves, shops should look for strong enough flavor, batch consistency, fit with their brewing equipment, controllable cost, and available origin information (Taiwanese chains must label tea origin).

5 Things to Check When Choosing Milk Tea Leaves
- Strength: the tea should still come through after milk, ice and sugar.
- Batch consistency: consistent aroma and strength batch to batch keep every cup the same.
- Equipment fit: loose leaf, no-filter bags or extraction bags must suit your brewing method; see No-Filter Tea Bags vs Extraction Bags vs Loose-Leaf Tea.
- Cost: compare tea cost per cup, not just price per kilo.
- Origin information: under Ministry of Health and Welfare rules, Taiwanese chains must label tea origin for freshly made drinks; see Taiwan’s Bubble Tea Labeling Rules.
Pairing Tea with Milk
- Creamer powder: shelf-stable with rich milky flavor, for classic milk tea and high-volume shops.
- Fresh milk: natural dairy flavor, for fresh milk tea drinks.
- Milk foam: layered on top for a different texture.

Brewing depends on the tea type and format. Suppliers usually give recommended water temperature, steeping time and tea-to-water ratio, and shops should test those settings and write them into their SOP. In general, black and oolong teas are brewed with water close to boiling, while green tea uses cooler water to avoid bitterness; filter-free tea bags and tea espresso bags follow the instructions on the pack.
How do I choose a wholesale tea supplier?
Start from your menu to decide the tea type and format (loose leaf, filter-free bags or espresso bags), then compare specifications, origin labeling, test reports and supply stability. Ask for samples and check that different batches of the same tea taste consistent before placing a first order. Tang Sugar can quote tea together with your other ingredients: see tea leaves.
