About alcohol never had any issue entering with a couple of bottles of wine, last time I was sent to the red line for scanning the baggage but the agent even he probably saw there were 3 bottles he could not care less. Another time was asked about content, just informed it was wine and not spirits plus one bottle of olive oil and he let me go. But there is always risk be that a zealous agent ask to open the bag and to declare (and pay) for the extra bottles, that's why I never take very expensive bottles, in the worse case I would just drop the bottles at the custom and leave.
