                                According to a study published in PMC, the bitterness in almonds is determined by the presence of the cyanogenic glucoside, amygdalin. Although prized for their buttery and sweet flavor, Marcona almonds can occasionally contain a rogue bitter nut, which is a rare but notable flavor issue for consumers. This surprising taste is caused by several factors, including genetic variances, cross-pollination, and improper storage.
