America's first water sommelier, Martin Riese, joins the host to discuss the widespread confusion around water testing, mineral content, and bottled water quality. Riese explains how he discovered his lifelong passion for tasting different tap waters in Europe as a child and eventually created water menus for Michelin-starred restaurants. They unpack the recent viral internet controversy over supposed contaminants in Mountain Valley water, debunking fear-mongering tactics and examining what metrics like TDS actually mean. Throughout the conversation, Riese demystifies marketing gimmicks, explains the science behind water's unique taste profiles from various terroirs, and emphasizes the importance of transparency and critical thinking.
Bunny XO opens the episode, explains her viral water testing incident and introduces Martin Reeser, America’s first water sommelier.
Reeser shares his childhood fascination with tap water, his hospitality career, and how it led to creating water menus and becoming a certified water sommelier.
Bunny shares the viral claims about Mountain Valley Water’s arsenic levels, Reeser investigates the company’s reports, and they confront the misinformation and the company’s response.
The hosts discuss how to test water, the limitations of TDS meters, and the importance of companies providing full water quality reports rather than relying on misleading labels.
The hosts discuss the prevalence of microplastics in both plastic and glass bottles, highlighting tire runoff as a major source.
They examine how paint on bottle caps can introduce microplastics into water during bottling processes.
The conversation turns to the low, non‑detectable arsenic levels in Mountain Valley Springs water and the myth of arsenic poisoning.
Martin reveals his new free app that provides water quality, sustainability, and brand transparency data for consumers.
They critique sensational claims about water safety, emphasizing the importance of evidence‑based information.
They discuss how total dissolved solids (TDS) affect taste, mineral content, and potential health risks like kidney stones.
The hosts weigh the pros and cons of tap water, filtration methods, and the need for infrastructure investment.
The episode ends with a call to action for better water infrastructure, education, and responsible content creation.
Childhood Passion for Tap Waterstory
The guest shares how his obsession with tasting different tap waters began at age four during family road trips across Europe.
Earning an Extraordinary Ability Visadata
The guest explains that he holds an O1 extraordinary ability visa for the United States based entirely on his expertise in water.
AI Data Centers Consume Waterinsight
The host and guest discuss the surprising environmental footprint of artificial intelligence, noting that a single AI query consumes about half a liter of water.
Bottled Water Environmental Impactinsight
The guest argues that bottled water has the smallest environmental impact of any bottled beverage because it simply bottles nature without agricultural production.
Debunking Home Water Testing Stripsstrategy
The guest reveals that cheap home testing kits and TDS meters found on Amazon have low accuracy and cause unnecessary panic.
Debunking Online Water Fear Mongeringinsight
The guest breaks down a viral social media video claiming dangerous arsenic levels in Mountain Valley water, explaining that trace amounts are naturally occurring and strictly regulated.
Putting Arsenic Levels in Perspectivedata
The guest illustrates how low one part per billion of arsenic is by comparing it to a single drop in an Olympic-sized swimming pool.
Tasting a High TDS Georgian Waterstory
The host and guest taste a mineral-heavy water from the country of Georgia with a TDS of 5,000, comparing its intense metallic flavor to medicine.
“I don't want to, I think when you stop learning, you stop living.”
“Without it, we wouldn't be here.”
“Because indirect water is the key word here.”
“All purified water is tap water.”
“The problem is what we're facing due to the change of, of the environment, what's happening right now.”
“Microplastic is everywhere. Everywhere, in every food you're eating, in every bottle of water, pretty much, everywhere is microplastic.”
“We need to get rid of plastic, guys. We need to find a new idea to, to, we need to attack the problem where it's a curse.”
“The paint has microplastic. And then I thought, but how is this ending up now into the water when the outside is thin?”
“When you put one drop of arsenic into an Olympic swimming pool, that's what that water has in the arsenic.”
“We need to put goals together to get better water into every single household in America. Because water is a human right.”
(Originally aired: 8/18/25) Season 10 is officially here, and we’re kicking things off with a splash! Bunnie Xo sits down with Martin Riese, America’s first certified water sommelier, to unpack the myths, science, and politics behind what we drink. Bunnie shares her own viral “water debacle” and what she learned from testing different sources, while Martin breaks down the subtleties of water taste profiles, the role of TDS (Total Dissolved Solids), and the environmental toll of bottled water. Together, they clear the air on false claims about Mountain Valley’s arsenic levels and stress the need for transparency and fact-checking in the industry. Martin also calls out the dangers of multi-level marketing schemes, debunks the rumor that sparkling water causes cancer, and highlights how basic chemistry and proper filtration can make all the difference. He taste-tests Saratoga, Mountain Valley, and even a rare 2,000-year-old Australian water with 1,300 TDS, while critiquing Perrier’s lack of transparency. Along the way, he explains why RO systems and shower filters are worth the investment, and why America needs to improve its water infrastructure instead of relying solely on bottled brands. The conversation wraps with Martin previewing his upcoming app, Sourced, which will offer free, reliable water education, and a reminder to approach water debates with compassion, curiosity, and a commitment to the facts.
