Yeah, well...... Ya live, ya learn. They haven't exploded yet, but I'm going to have to drink a lot of beer quickly!
Other than that, flavor-wise, the straight kit is the strongest, very citrusy aroma, sharp bite. The kit with wine yeast is not as sharp and the aroma has more caramel. The batches with mango were virtually identical (one more like a small bottle of champagne when you open it) The aroma and flavor of the mango isn't as strong as I would have thought, but it's there in the background when you're looking for it, especially the flavor.
