What was I drinking?

Hello, I’m 16, and around 2 years ago I took some alcohol from my parents because they had a huge stash. I got caught and punished and that was the end of it, this post isn’t asking for ways to get alcohol underage or anything like that, in Germany where I live you can drink beer and wine at 16 and get any other alcohol easily.

(Sorry for that long mini paragraph but I don’t want anybody getting the wrong idea)

Well anyways I took from my parents over the span of a year around a liter of whiskey, a liter of rum, a bottle of gin less than a liter, and a bottle of an alcohol im not quite sure about, that’s why I’m asking here.

I found it in a sort of wine bottle with no label and no signs of a label like any glue marks or anything, it was pale but had a pretty slight yellowish tone. It just had a normal wooden cork. It tasted very similar to whiskey and it was as strong or stronger than the whiskey I was drinking which was 54% if I remember correctly, it was in the 50 percents for sure though.

Can anybody tell me what I was drinking, out of curiosity? Thanks!!
