I have never been to Slovenia but have had nothing but good experiences with Slovenes in my travels. But be careful with their Moonshine should you be offered some. It is potent!
I don’t drink moonshine here in the US. I certainly would not drink it outside the US.
It is like these people who have gotten sick or died in the Dominican or Mexico over the last few years. They drank bootleg liquor. The bottles probably did not say Bacardi, Absolut, Jim Beam, Jose Cuervo or other legitimate worldwide brands. They probably were some off brand they had never heard of before. What the H#LL is was free. What’s the worst that could happen. Well, you could die.
So, no in foreign countries or even traveling in the US, I am always careful what I eat and drink. It is like being aware of not eating SHELLFISH unless it just came off the boat. Even then you are still taking a chance.
