• acetaldehydearomaaldehydereads as pungent, fruity odor (PubChem)Measured in 18 of 338 ingredients.cite

  Not detected in Y7; 0.5 g/hl pa in Y8; 0.6 in N2; 0.6 in N3. In the seven home-distilled samogon samples of the same table and the same column the values are 9.8, 10.9, 13.2, 16.3, 19.1, 23.1 and 29.4 g/hl pa — between sixteen and sixty times higher. The paper prints the Russian GOST limit for acetaldehyde as 0.01 and the AMPHORA limit as 50 in the same table. — Solodun et al. 2011, (Table 2, 'Volatile composition of Russian alcohol products', Acetaldehyde column, rows Y7, Y8, N2 and N3 (the four commercially produced vodkas of Table 1))
• 1-propanolaromaalcoholreads as burning taste (PubChem)Measured in 22 of 338 ingredients.cite

  '1-Propanol, often used as an adulteration marker, was detected in 10 samples. However, its concentrations were very low, reaching 3 mg/L in sample 25 (originated from the US).' One sample (3, Turkey) reported a much higher value (90 mg/L) that the paper itself flags as anomalous and excludes from discussion ('such high concentrations are unusual for "pure" vodkas and may indicate presence of aroma additive... this sample was not considered within the discussion of the results') — that outlier value is not landed here. This directly contradicts PMC3274728's four Russian vodkas, all of which report 1-propanol as not detected; the two papers together show 1-propanol presence is brand/market-dependent rather than a fixed absence in vodka as a category. — N.Kh.

• isobutanolaromaalcoholreads as sweet, musty odor (PubChem)Measured in 24 of 338 ingredients.cite

  3 mg/L in sample 25 (US) only — the paper states explicitly this compound 'was not detected in all other samples' of the 26 surveyed. The rarest of the impurities this method screened for. — N.Kh.

• p-cymenearomaterpenoidreads as mild pleasant odor (PubChem)Measured in 42 of 338 ingredients.cite

  Detected (presence/absence only) in all four named commercial vodkas (K1, K2, K3, K4) — the only compound in this 29-peak HS-SPME/GC-MS panel present in every sample regardless of feedstock (cereal or molasses alcohol) or filtration treatment. — Lucie Siříšťová et al. 2012, Czech Journal of Food Sciences (Table 4, row 'Cymene', columns K1–K4)Measurement only — the source text is licensed facts-only.
• limonenearomaterpenoidreads as pleasant lemon-like (PubChem)Measured in 91 of 338 ingredients.cite

  Detected (presence/absence only, no concentration given) in three of four named commercial vodkas: K1, K2 and K4, not detected in K3. K4 is described in the text as 'imported Russian vodka' containing 'natural substances such as limonene, cymene, and ethyl esters of carboxylic acids C4, C8 and C10'; K3 is described as 'produced from molasses alcohol' and differed from all other samples across the whole VOC panel. — Lucie Siříšťová et al. 2012, Czech Journal of Food Sciences (Table 4 ('VOC identified in commercial vodka samples K1–K4 analysed by HS-SPME/GC-MS'), row 'Limonene', columns K1–K4)Measurement only — the source text is licensed facts-only.
