Protect Beer's Main Ingredient

Celebrate OktoberForest!

If you like beer, you should love forests.

Beer is 95% water. And 40% of the world’s usable water comes from forests. Help protect beer’s main ingredient. Help us plant one billion trees!

Love Beer? Love Forests! OktoberForest is a month-long celebration of clean water, great beer and the forests that make it all possible. © The Nature Conservancy

Beer - Water - Forests

Beer has four main ingredients: water, grain, hops and yeast. While water may seem like beer’s simplest ingredient, there's a lot involved in getting that clean water to our taps.

Clean, plentiful water depends on healthy surrounding natural areas, like forests. Forty percent of the world’s usable water is stored and filtered through forests. From the tree canopy all the way down to root systems, every part of a forest plays a critical role in cleaning and protecting our water supply. Tree canopies of large forests—like the Amazon Rainforest—influence rainfall patterns across the globe. They produce moisture in the atmosphere, known as “rivers in the sky,” that fall as rain locally and thousands of miles away.

It’s not an obvious connection: beer and forests. But, we hope the next time you enjoy a pint, you give a nod to the trees.

Healthy Forests = Clean Water = Great Beer Beer and forests may seem like an odd connection, but forests provide 40% of the world's usable water, beer's main ingredient.

About Plant a Billion Trees

Our Plant a Billion Trees campaign is a forest restoration effort with the goal of planting one billion trees across the planet. Trees provide so many benefits to our everyday lives. They filter our air, provide fresh drinking water, help curb climate change and create homes for thousands of plants and animals.

One BILLION is a big number, but we know we can do it with your help.
