The Bottanicals

Sophisticated taste from unique Thai herbs

Pegha

A rare Thai botanical
flower with a subtle herbal bitterness.
The heart of our Floral flavor
- found nowhere in imported tonics.

Citrus peels

Organic Thai citrus
- orange and lime,
hand-selected for their
bright , clean bitterness
and natural complexity.

Fresh green cardamom pods on a wooden spoon and surrounding surface.

Cardamom pods

Thai cardamom adds
a warm, aromatic depth
that rounds out the bitterness
- a signature note you'll
notice on the finish.

"Thailand has some of the world's most remarkable herbs. Why were we pouring imported tonic over them?"
