We gave it a go in Spring 2011.
It was fun to try but reducing the sap to usable syrup is too energy intensive to make it worthwhile…
However in Spring 2012 Dick Harris kindly supplied us with 4 bottles of delicious birch sap wine that he brewed in N8 from birch sap tapped in N10!

Sap tapping on youtube:
quote from: http://www.woodlife.co.uk/2010/03/29/bush-tucker-men/:
We had a go at tapping birch again and the tree generously gave up some refreshing liquid. We also tapped Hornbeam which is a first for me. The sap came out just as fast but I noticed it wasn’t quite as sweet as birch sap but just as refreshing.
