They will see the wine on the scanner screen as your carry-on is x-rayed. Most times nothing is said. However, twice I've been stopped by one of the security agents since the new regulations took effect.
I carry the wine in special protective bottle protectors (bubble wrap with heavy plastic outer cover). Once, I think they just wanted to be sure it was wine and not spirits since a red wine bottle resembles a whisky/rum/vodka bottle. The other time was because I had all 4 bottles in my carry-on and the security agent wanted to confirm we had two adults in the cabin. Didn't help that DW went through security ahead of me and took off for the check-in desk before I'd even had my bag screened. When she noticed I wasn't behind her, she returned and the agent waved us on through. On our last cruise I told her we would stay together, at least until we cleared security screening, but we weren't stopped, questioned, or anything like before.
