Years vs. Summers: How Colorado Truly Aged Our 100% Malted Rye Whiskey

Whiskey drinkers love to talk in years. Four‑year. Six‑year. Twelve‑year.

But here’s the truth every craft whiskey founder eventually learns: years don’t age whiskey — seasons do. And in Colorado, seasons don’t behave the way the rest of the country expects.

At Anderson & Link, we’ve seen firsthand how summers, shoulder seasons, and even unseasonably warm winters shape a whiskey far more than the calendar ever could. Our current bottled whiskey — barreled in March 2020 and aged in Colorado until June 2024 — is the perfect example.

Let’s break down why.

What a “Summer” Really Means in Whiskey Aging

A “summer” isn’t a date on the calendar. It’s a period of sustained heat where the whiskey expands deep into the oak, dissolving sugars, pulling out lignin and tannins, and building the structure that defines mature whiskey.

A true summer requires:

• Consistent daytime highs in the 80–95°F range

• Repeated day/night expansion–contraction cycles

• Weeks or months of uninterrupted heat

  
  

This is the engine of extraction.

Colorado’s Climate: The Great Accelerator

Colorado’s climate is a gift to malted rye:

• Hot days, cool nights

• Low humidity

• High elevation pressure swings

• Big temperature differentials

  
  

That means more “breaths” per year — more cycles of whiskey moving in and out of the oak — than in milder climates like Kentucky or coastal regions.

This is why a Colorado four‑year can drink like a six‑ or seven‑year whiskey from a gentler environment.

How Many Summers Did Our Whiskey Experience?

Our current bottled whiskey followed this path:

• Barreled: March 2020

• Aged in Colorado: March 2020 → June 2024

• Time in Colorado: 4 years, 2 months

• Proofed into three expressions:

• 90 proof

• 100 proof

• 122.7 proof cask strength

  
  

During that time, the barrels experienced:

Four full Colorado summers

2020, 2021, 2022, 2023 — each delivering sustained heat cycles and deep extraction.

A partial 2024 summer

We bottled in June, after the first warm pulses of the season.

Multiple unseasonably warm winter stretches

Denver saw several winter weeks in the 50s, 60s, and even low 70s during this period — especially in 2022–2023 and again in early 2024.These didn’t qualify as full summers, but they absolutely acted like bonus maturation windows, adding extra expansion–contraction cycles when the whiskey would normally be dormant.

Final maturation reality:

Four full summers + a partial fifth + multiple warm‑winter extraction bursts.

That’s why this whiskey drinks older than its age statement.

Why Warm Winters Matter (But Aren’t “Extra Summers”)

Even in a winter that “barely acted like winter,” like Denver’s 2025–2026 season, the heat isn’t sustained enough to count as a full summer. But it does create:

• More micro‑extraction events

• More pressure swings

• More evaporation

• More oak interaction than a normal winter

  
  

Think of these warm spells as extended shoulder seasons — not full summers, but absolutely meaningful for maturation.

For malted rye, which thrives under intensity, these extra cycles add depth, color, and structure.

Why This Matters for Drinkers

Two whiskeys can both be “four years old,” but if one lived through:

• Four Colorado summers

• A partial fifth

• And multiple warm‑winter extraction cycles

• 
  

…it will taste dramatically more mature than a whiskey aged in a mild, steady climate.

This is the story behind Anderson & Link’s current release — and it’s why our 4‑year‑and‑2‑month malted rye shows the richness, spice, and complexity of a whiskey that’s lived a much more dramatic life.

The Anderson & Link Way: Transparency, Terroir, and Truth

We don’t just print an age statement. We tell the story behind it.

Our whiskey isn’t simply “four years old. ”It’s four Colorado summers old — plus the bonus maturation that only our climate can deliver.

That’s the difference between aging by the calendar and aging by the seasons. And it’s the difference you taste in every bottle of Anderson & Link.
