In the run-up to last week’s Mixology Monday I compiled a list of mint-containing drinks that I thought I’d like to sample. I made my way through three of them but had only so much time to allocate to drink, leaving other potential worthies untasted. In particular, I’d wanted to examine the Derby, for which I found two distinct recipes: one with peach bitters (in Craddock, Duffy, and Trader Vic’s), the other with peach brandy (in Embury and Beebe).
I don’t know when peach bitters entered their decline — CocktailDB implies that they failed to survive Prohibition, though Bergeron is calling for them ‘48 — but I suspect the reason that later authors employ peach brandy is that the bitters were growing scarce, if not already extinct. Lest customers seeking Derbies go unserved, brandy was substituted. Fortunately (and thanks in no small part to Ted Haigh), Fee Bros. has reintroduced peach bitters to the bartenders’ arsenal, so the merits of Derby evolution may be assessed.
