Growers & Exporters

Who we are, what we do and why we do it.

Who We Are

 With five generations of coffee growers in the family, Third Wave Coffee Source has sprung from a rich tradition of coffee. Our passion for exquisite beans goes beyond meeting the discerning expectations of the third wave coffee movement. We have been refining coffee processes and searching for the best farms long before the world caught up.

Originating in Guatemala, we have now extended our base to reach the newest and best micro-lots and single estate farms across South America. Through trade links in Europe and North America, we bring roasters and coffee specialists direct to origin, exporting our own and our friends’ finest specialty coffees to delight the most cultivated palettes.

  • Nadine Rasch

    Nadine was born and raised in Guatemala and spent much of her childhood on her family’s coffee farm. She studied Finance and German at Santa Clara University in California. During her studies she interned at the central purchasing lab for Starbucks in Lausanne, Switzerland and at a coffee futures brokerage in Miami, FL. She then moved to the UK to study a Masters in Finance at the London School of Economics. She worked in finance for a year, but soon realized she wanted to be passionate about her work. She then joined Mercanta, a specialty coffee broker in London to focus on sales in the German markets and then took on all of the shipments from origin to the UK and USA warehouses. During her time at Mercanta she took numerous courses at the London School of Coffee and cupped daily with the rest of the team. Realizing the potential in the specialty coffee market, she returned to Guatemala to work on her family’s various farms implementing better quality in every step of the coffee production. She then partnered with Samuel to create Third Wave Coffee Source in search for the newest and best micro-lots and single estate farms from Guatemala and all of South America bringing them directly to the best roasters around the world.
