Comment on Brewed up some tree beer
MuteDog@lemmy.world 4 days agoI knew some armchair researcher was going to post this crap. Toxic to ruminants does not equal toxic to humans. All parts of the Poderosa pine from the needles to the inner bark were/are a staple food of native Americans. Isocupressic acid is not toxic to humans.
I don’t mean to insert myself in some “armchair researcher” discussion, but Leyland Cypress is from the family Cupressaceae, not Pinaceae like the Ponderosa pine.
So how does the Ponderosa pine being edible prove anything about the leyland cypress? They are in the same class of pinopsida, but diverge and have different orders, families, genuses, and species below that.
You’d be better off comparing the leyland cypress to other cypresses than to ponderosa pines for edibility I think.
I did. Made the same argument, too.
Yes, I’m aware that they are completely different species. If you read the sources that Stickyfingeritchybum (ew, btw) posted they’re talking about the toxicity of Isocupressic acid in cattle and sheep, this acid occurs in both Leyland Cypress and all parts of Ponderosa Pine. Therefore since natives ate Ponderosa Pine as a staple food (apparently the inner bark is sweet and was considered a dessert) we can conclude that Isocupressic acid is not toxic to humans. This acid is also quite high in common juniper which is what is used to brew Maltøl and Sahti and is the primary botanical in Gin. Additionally, the only reported toxic effect of this acid on cattle and sheep is inducing abortion; Pregnant people aren’t advised to be drinking alcoholic beverages to begin with so kind of a double moot point.
I appreciate people being concerned for my health, but seriously, I have actually researched this beyond just googling and finding an article that ONLY talks about this being toxic to cattle and sheep and makes no mention of human toxicity. I’ve been brewing and drinking beers with this tree for nearly 10 years with no ill effects. Farmhouse Maltøl and Sahti brewers have been putting Isocupressic acid (via juniper) into their beers for thousands of years.
we can conclude that Isocupressic acid is not toxic to humans.
Well, no. We can say we don’t know. The toxicity profile on various sites say we don’t know. Most likley because no one thought to do it. hmdb.ca/metabolites/HMDB0253626
You are inferring its safe. Not the same thing as being safe. That’s your business. Enjoy your cattle morning after pill beer. Just don’t tell people it’s safe and “I did the research”.

Hey, I am just skimming through and see that you are saying that the ponderosa pine is edible, while making beer from the Leland Cypress. These plants are similar looking, but different species completely.
Here are a few more sources that advise that it can be toxic to humans.

Also note that a book on plant toxicology was referenced in the Wikipedia article.
I can’t say whether there would be any effect on you from making a beer from it, but I am concerned that you had said it was fine because the ponderosa pine is edible. I would consult a specialist before drinking any more of this brew.
