I *really* want to tell you they taste awesome now, but unfortunately it's not the case. When they ripen in spring/summer they beat any other guava I've eaten (or my in-laws and they have several trees in Brazil). But right now, they were pretty bland.
That's nice to have some now, even if they aren't at their best. Mine are only 2 year old seedlings or cuttings, so maybe this coming summer/Fall, I might get to try my very first back yard guavas. I have a few varieties, Emperor, Pearl, Thai/Bangkok giant, lemon guava, Malaysian Red, Paul Thompson, Mexican cream, un name orange and pink flesh, Chinese guava and Beaumont guava. Beaumont is the biggest of the batch, so that one, is the most likely candidate for hopefully some fruits this year.
