Capella produces water-soluble, food-grade flavours. Cup a Joe delivers a clear coffee profile: roasted bean character with a mild espresso bitterness, rounded by cocoa/toffee and a soft caramel finish. Excellent solo or as a base in dessert and coffee-style blends.
Use: Concentrate that must be diluted. For e-liquid, mix into PG/VG (and nicotine if used) per the guidelines below. For culinary use, very small amounts are sufficient. Note: We buy in bulk and re-bottle into smaller sizes (non-OEM packaging).

FAQ
Black coffee or latte?
Base is roasted coffee. Lower % reads “black”; add cream/vanilla for latte/cappuccino vibes.
Can I add it straight to a tank?
No—this is a concentrate and must be diluted first.
PG-based?
Yes—Capella flavours are water-soluble and typically PG-based.
Why not the original bottle?
We purchase in bulk and re-bottle into 20/50/100 mL for better pricing and availability.
