Back Hopp"ENING"

I brewed my first brag got–OG 1.12, FG 1.018.  Used local honey and local hops.  Problem: after setting up and doing my mash I noticed one problem…the local hops were more than 2 YEARS OLD!!!  So I could have been more prepared, I realize that.  The final braggot needs more bitterness to mellow the sweetness.

  1. How can I do that?
  2. Will Hop extract post boil give any bitterness, or will it only contribute aroma?
  3. Could I boil water and hops and add that back to the finished braggot?

Y’all are great. Always appreciate the help
