The most frequent error in citrus coffee preparation involves store-bought pasteurized juice. Commercial carton juice undergoes heat processing and de-aeration, stripping its volatile aromatics. Many manufacturers replenish flavor using "flavor packs" composed of ethyl butyrate. When mixed with hot espresso, these artificial esters degrade into a harsh, metallic aftertaste. Freshly squeezed oranges, particularly varieties like Valencia or Navel, are non-negotiable for flavor stability.

Another common mistake is brewing hot espresso directly into an empty glass and splashing cold juice on top. Pouring cold juice into hot espresso shocks the extraction, creating rapid clouding and unappealing thermal degradation. Always build the drink cold: juice first over ice, espresso floated last.

Finally, avoid over-extracting the espresso. An extended pull running past 35 seconds draws out astringent polyphenols and heavy quinic acids. When combined with the high acidity of citrus, these over-extracted compounds trigger intense drying sensations on the sides of the tongue. Keep the pull tight, sweet, and focused on early-phase extractions.
