That heavy water (D2O) tastes sweeter than normal (H2O) water.
That was a subject that was debated back in the '30’s/'40’s among scientists. They claimed no difference. But what the heck would those smart-a$$ Scientists know??
I’ve actually taken (well… sneaked) a small sip of D2O up at Argonne long time ago. Tasted the same to me as distilled H2O. Sorry… no TN!!

In college, Harold Urey would often show up at the campus greasy spoon burger joint in the woods for lunch. He’d sometimes join us for lunch. Not sure what he was drinking
Pretty amazing to think that deuterium was only discovered in 1931. Not much more than a decade later we had learned enough to control fusion, and build atomic bombs.
As a huge chemistry nerd (major in college, former high school chemistry teacher, chemistry lab researcher, and biomedical engineering masters) I have always admired the DIY chemistry experiments of Cody on YouTube. His video suggests that heavy water does in fact taste sweet and blinds his girlfriend as a demonstration;
I recommend watching his other videos if you are into this sort of thing.
Irrigation with heavy water to increase detectable sweetness without changing residual sugar??? Probably not economically viable.
Livermore Valley wine has elevated levels of tritium. It partly came through rainfall, so it’s part of the terroir. Some European wines have higher levels, though.
