Black Tea, Green Tea, and Herbal Tea: What Makes Them Different?

Whether you’re a tea traditionalist, a green tea devotee, or someone who loves winding down with a calming herbal infusion, not all teas are created equal—and that’s part of the magic. At Libertine Blends, we’re passionate about all types of tea, and how each one can bring something unique to your day. Here’s a simple guide to help you understand the key differences between black, green, and herbal teas—and how to choose the right blend for the moment you’re in… 

1. Black Tea (Camellia sinensis – fully oxidized)

• Origin & Processing: Crafted from the same Camellia sinensis plant as green tea, black tea undergoes full oxidation, turning the leaves dark and deepening the flavour.
  

• Caffeine Kick: Naturally caffeinated — perfect for when you need a bold morning boost.
  

• Taste Profile: Rich, malty, and full-bodied, often with coppery hues and brisk notes.
  

• Libertine Favourite: Roxy Black is a classic breakfast blend, made from organic Assam, providing that bright, warming, full-flavoured start to the day.
  
  

2. Green Tea (Camellia sinensis – lightly oxidized)

• Origin & Processing: Also from Camellia sinensis, but minimally oxidized (often immediately steamed or pan-fired) to preserve freshness.

• Caffeine Level: Lower than black tea—steady energy without the jittery spike.
  

• Taste Profile: Clean, grassy, sometimes floral or subtly vegetal, with a light natural sweetness.
  

• Libertine Pick: Lightning Green is a refreshing blend of sencha green tea and invigorating ginkgo—designed to naturally uplift your morning or afternoon with a clear-eyed energy boost.
  
  

3. Herbal Tea (Tisane – caffeine-free)

• Origin & Processing: Herbal teas don’t come from Camellia sinensis. Instead, they can be a blend of herbs, flowers, fruits, roots, or spices.
  

• Caffeine: Naturally caffeine-free—great for any time of day or night.
  

• Taste & Benefits: Highly diverse—ranging from floral and soothing to spicy and invigorating. Frequently chosen for therapeutic or mood-enhancing properties.
  

• Libertine Favourites:
  

• Runaway Rose: a delicate and calming floral blend.
  

• Minty Ohm: a refreshing midday palate cleanser.
  

• Kapow: spicy and warming, a caffeine-free kick packed with kawakawa, lemongrass, cardamom, and chilli.
