I made my first batch of mead earlier this year, predominately from last year's poplar honey.

I know we should've aged it longer, but as is it was a huge hit with my husband (who hates wine) and in-laws (wine-lovers).

The problem is I couldn't find any poplar honey this year. When I asked around I was told it's not good for making mead, but never got an answer why.

So what's the deal? And is there a good substitute?
