Mitzvot

Although some (I believe minority although minor be wrong ) of the poskim are machmir in Halacha with prohibiting opening regular plastic bottles due to make B’patish, do they all permit opening a glass bottle since the cap isn’t screwed off but popped off?

Is the concept of davar charif, found in Hilchot Yoreh Deah/Issur Veheter considered as subjective depending on what an Individual finds spicy in Halacha or no, is it universal?

Some poskim rule using aged wine for kiddush (40 days) as hiddur mitzvah, also wine being aged affects the Halacha for Hatov vehameitiv. If a Jewish Astronaut is in space, do they use the earth zemanim/time to determine a wine’s age or outer space’s?
