Creating a Recipe: Two Temperatures You Can Repeat

Fraction tasting is the slow, expensive part of learning a new base material. The payoff is that you do it once, then you never have to do it that way again.

In this approach, a recipe is mostly two temperatures: where you start keeping, and where you stop. Once those are set, you can run the same spirit again with three larger containers and consistent quality.

Quick summary

Context: recipe development vs repeat runs

Treat the detailed fraction line as training. Once your cut points for a given base (the same wine, the same process), you can dial them in and reproduce the same recipe in future runs.

Two temperatures, not twenty beakers

Once you choose the fractions you want, you only need to record the start and end temperatures of the kept blend. Those are the two values you dial into control.

When tails are worth collecting

You could keep collecting tails deeper (for example to 95°C or 96°C), but the argument here is there’s little reason in brandy: it costs energy and time and adds heavy back-end character that can work against a fruit-forward profile.

Aging and dimensionality

Aging changes what you can “afford” to include. If you plan longer maturation, you can go deeper into tails because you have time for those heavier components to mellow.

Why deeper tails need more time

If you include deeper tails, plan on longer aging windows. Legal minimums are mentioned as examples: whiskey needs at least three years of aging in Europe, and can be two years in America.

Dilution: proof, flavor, and clouding

After blending, you dilute to bottling strength. Practical targets are 43%, 44%, or 45% for brandy, and treats 42% to 43% as a low end for fruit brandy.

Why not 40% (in this argument)

Two reasons are given for avoiding 40% as a craft distiller: more dilution reduces flavor intensity, and lower proof reduces solvency power. If tails oils are present, they can come out of solution and cloud the drink at lower proof.

A claim here is that big producers choose 40% partly for volume economics: dropping from 44–45% to 40% yields more bottles.

Run #2: automate the recipe

After you have your numbers, you rerun the same base material and collect in larger containers: one for heads, one for hearts, one for tails. This point is consistency: you can replicate the same recipe on the same system, and the same cut temperatures can be used when scaling to larger automated units (with air pressure correction handled by automation in that framing).
