MateVeza Adds New Herbal Offering to Its Signature Line of Yerba Mate Based Ales

New Organic Morpho Herbal Ale Features Hibiscus Flowers & Bay Leaves

SAN FRANCISCO, August. 15 — MateVeza has released Morpho Herbal Ale, an organic ale brewed with yerba mate, hibiscus flowers and bay leaves. A collaboration with Mill Valley Beerworks, MateVeza’s newest limited release is an ode to the Morpho butterfly of South America. With hints of tropical flora from hibiscus, the lemony herbal notes of bay leaves, and an earthy dry yerba mate finish, this ale is pure rainforest refreshment.

Morpho Herbal Ale is part of a new chapter in the lost art of unhopped ales called gruits that originated in the middle ages. Gruits rely on a mixture of herbs to provide the bitterness resulting in zero hop bitterness. Morpho Herbal Ale’s bitterness is provided entirely by the yerba mate and bay leaves, providing a completely new and refreshing take on the style.

After discovering their mutual appreciation for Stephen Harrod Buhner’s book “Sacred and Herbal Healing Beers,” MateVeza founder Jim Woods and Mill Valley Beerworks cofounder Justin Catalana discussed collaborating on a gruit with yerba mate. Catalana brought his experience brewing with bay leaves and Woods his experience brewing with yerba mate. After their first batch, Woods suggested hibiscus flowers for an added citric acid tartness and tropical aroma.

“In a craft beer climate dominated by ales that push the limits of hop bitterness, Morpho Herbal Ale is a rare creature,” said Jim Woods, founder and president MateVeza,“After receiving rave reviews of the beer’s unique melange of flavors from the customers of Mill Valley Beerworks, we knew we were on to something.”

Catalana and Woods decided to bottle their exotic creation and the Morpho butterfly was chosen as the perfect flag-bearer. Native toSouth America, where yerba mate is grown, the iridescent blue Morpho butterfly flutters through the rainforest in search of fermenting fruit. The beer’s tropical aroma and striking red color make it an apt expression of the Morpho butterfly’s beauty.

Morpho Herbal Ale was made possible by a loan from The Boston Beer Company’s new microloan program for craft brewers, Samuel Adams Brewing the American Dream. After he was unable to secure additional financing from traditional banks, Jim Woods applied for a Brewing the American Dream loan, and received the necessary working capital to undertake Morpho Herbal Ale project.

Morpho Herbal Ale will be available in 22-ounce bottles and draft in select locations throughout California, Oregon, Washington and Colorado. For more information, sales information and high-res imagery visit
