How to fetch a single value with an entity metadata wrapper?
Well you could use:

$node = node_load($nid);
$wrapper = entity_metadata_wrapper('node', $node);
$title = $wrapper-&gt;title-&gt;value();


But if that's literally all you need to get from the node, an EntityMetadataWrapper is overkill in my opinion. Just use:

$node = node_load($nid);
$title = $node-&gt;title;
