Coffee contains tannins that can stain teeth, acid that can erode tooth enamel, and caffeine that can dry out the mouth, reducing saliva production and leading to an increased risk of cavities.

For Coffee Drinkers,

By Coffee Drinkers

Tannin was born from our own frustration with cofffee's oral impact. Giving up our coffee wasn't an option, so we created Tannin instead.

Support Baristas &
Coffee Workers

As former baristas ourselves, we know the financial struggle of the service industry. That’s why a portion of our profits go directly back to the people who make coffee happen

Tannin’s aluminum bottles are meant to be refilled and re-used. We chose aluminum because of it’s low impact and high reward.
