Thank you
Answer
Thank you for your question,
Wine bottles that have cork openings not screw bottle openings may be opened on shabbat. (Shemirat shabat kehilchata 9;21).
Regarding other caps there is a machloket if it is permitted to open them on shabbat. Some say that one may open all types of caps. some say that only plastic caps may be opened. others hold that all caps may not be opened. One of the solutions is having a kid open the bottle. (See Shemirat shabat kehilchata 9;18). see also Minchat asher (part 1; 28). See also here: https://ph.yhb.org.il/en/01-15-13/ ,
All the best!
