Note 7 — Chapter I · On the Intimate Relation existing between the Deterioration of Beer, or the Wort from which it is Made, and the Process of Brewing.
Frank Faulkner translation
[The expressions “high” and “low” fermentation or beer strictly refer to temperature, whereas the other expressions used (“top” or “bottom”) refer to the behaviour of the yeast. The French words haute and basse seem to look both ways.—D. C. R.]
