ZONE 02 — AI-COLLATED SUMMARY

AI-ASSISTED · FROM GRADED PUBLIC SOURCES

Fernet Stock is a Czech fernet-style herbal bitter produced in Plzeň by Stock Plzeň – Božkov s.r.o., part of Stock Spirits Group. Its recipe traces to Italian founder Lionello Stock's 1884 Trieste company, but the spirit has been made and marketed in Czechoslovakia/Czech Republic since 1927, nearly a century of continuous local production and identity. The core product is macerated from roughly 14 herbs including gentian, Roman chamomile, blessed thistle, quinine and orange peel, at either 38% ABV (producer page) or 40% (Wikipedia), alongside a range of lighter flavoured variants (citrus, cranberry, honey, pear, mint) at 27-30% ABV. The Honey variant's ABV is an editorial estimate, not producer-confirmed.

AI-collated from the graded sources below; operator review pending. Re-verified against live re-fetch 2026-07-09: two defects corrected (Honey ABV was unsourced, serve specs had fabricated ml quantities) before publication.

SUBCATEGORY fernetRING coreTRADITION World amaroSELF-IDENTIFIED “Fernet-style herbal bitter”

The original Fernet Stock, introduced in 1927 by Stock Plzeň-Božkov (founded by Italian entrepreneur Lionello Stock, who purchased the Božkov distillery in 1920). A dark, bitter herbal liqueur macerated from around 14 herbs, of which the producer discloses gentian, Roman chamomile, blessed thistle, quinine and orange peel; the remaining botanicals are kept secret. Herbs are steeped in triple-distilled 65% spirit for a minimum of eight weeks, then lightly sweetened at 15.6 grams of sugar per litre, giving a balanced, distinctly bitter and herbal character. The producer-official ABV is stated as 38 percent; Wikipedia gives the Czech original at 40 percent (with an Italian-market version at 41 percent) — a genuine figure discrepancy across sources, not a data error.

  3. [3]BStock Spirits corporate site · Stock Spirits Group · producer-official · accessed 2026-07-09Re-verified 2026-07-09: this corporate page describes Stock Spirits Group generally (Warsaw-registered, 140 years, 80 brands, 7 production sites including 2 in Czech Republic) but does not itself state the full legal entity name 'Stock Plzeň – Božkov s.r.o.' verbatim. That name is corroborated instead by convergence across this site's brand/location framing, Czech Wikipedia ('Stock Plzeň'), and English Wikipedia's Božkov-Plzeň ownership narrative. Downgraded from A to B to reflect that no single source states the full legal suffix directly.
