Q. Can one be yotzi mishloach manos by giving a soda bottle? How about an expensive plain mineral water?
A. Horav Shlomo Miller's Shlit'a opinion as well as other Poskim is that one does not comply with any kind of water drinks, even carbonated and expensive mineral water. However, flavored and colored soda such as coke is acceptable. (See similar in Yebakshu Mipihu).
In regards to carbonated transparent but flavored water the Rov's opinion is that one should avoid sending water bottles.
