10 Things You'll Get With CO Specs

Learn what’s inside…

1

The “Definitive Spec” for 200 classics, distilled from hundreds of historical texts so you never have to second-guess a recipe again.

2

Visual proof straight from the source – see actual torn-out pages from the original bar manuals, so you know exactly where these recipes come from.

3

The authority to stop second-guessing yourself – whether you're making drinks for two or twenty, you'll know your recipe is historically accurate and perfectly balanced.

4

Freedom from “recipe rabbit holes” – no more sifting through endless conflicting versions online.

5

Tell the stories behind every drink – impress your peers and guests with your knowledge and clever anecdotes.

6

A book that's actually beautiful enough to leave out – coffee-table luxury that feels as good as it looks.

7

The certainty that you are serving the best possible version, replacing “I hope this tastes right” with “I know this is perfect.”

8

Earn instant credibility – having in your repertoire the greatest classic cocktails of all time.

9

Find any classic in 10 seconds – alphabetized, not buried in chapters.

10

The “final word” on cocktails – your permanent reference, not another trendy book that'll be outdated next year.

BUILT FOR HEAVY USE

Published in a hardbound A5 size, it fits nicely in the hand and is easy to carry around. At over 3cm thick, it’s satisfyingly substantial.

WHAT'S IN A NAME?

C & O are the author’s initials. ’Specs’ is bartender parlance; a shortening of ‘specification’ (aka a recipe). This project began as Cas’ work on his own personal recipes, and later morphed into a book — hence ‘the CO Specs’.

TESTED (to death)

Each drink has been scrutinised, tested, then tested again to achieve the ‘goldilocks’ balance of ingredients. Informed by history, balanced for now.
