Good ideas but there are about a dozen equally valid solutions to the grid. Lady Grey can swap with Earl Grey, as they're both types of tea and both begin with titles (also, I'm not sure,but I think it's English Breakfast tea, not just Breakfast tea). Oolong could swap with Breakfast Lady Grey,or Green - Oolong is a tea, Fast, Grey and Green are adjectives (colours are adjectives as well as nouns).

@Malcontent Thanks for commenting on my grids :)
I think I try so hard to add red herrings that I end up with these cases were multiple solutions are possible + I hadn't even spotted that Breakfast includes an adjective. I might just edit it and swap Breakfast for Rooibos or something. I only just started making grids yesterday. Still learning. Thanks for the feedback.

I believe I fixed it. I took out Lady Grey, so you can't swap her with Earl Grey anymore. I put Oolong in the tea category and Breakfast in the 'contain adjectives' category. And you can't swap Oolong with Breakfast, because as you correctly informed me, the tea name is English Breakfast. My mind hurts now.
