Do not make strength or health assumptions from the word bitters. Martina's prose says olive brine while its list specifies cocktail-onion brine. The Last Mechanical Art calls Beta Cocktails a year after 2009, whereas later references date it 2011. These discrepancies remain visible.
Simonson2021, Gun Metal Blue through Mezcal Corpse Reviver; supplied PDF ordinals 65–78. Full book reviewed; source paraphrase, not quotation.
The recipes show color alongside flavor in Gun Metal Blue, a substantial bitters measure in Johann Goes to Mexico, equal measures of forceful bitter ingredients in The Last Mechanical Art, brine and raicilla in Martina, and a revised citrus combination in Mezcal Corpse Reviver. Mezcal Collins is a deliberately minimal spirit-and-soda presentation.
