What is Grain-to-Glass Distilling?

August 29, 2026 · True Theory Spirits Team · 4 min read

Walk into most liquor stores, and you'll see dozens of bottles labeled "craft" or "artisan." But here's a secret the industry doesn't advertise: many of these brands don't actually distill their own spirits.

The Industry's Open Secret

A surprising number of "craft" distilleries buy neutral grain spirits (NGS) — essentially industrial alcohol — from large producers, dilute it, add flavoring, and bottle it as their own. It's legal, it's common, and most consumers never know the difference.

What Grain-to-Glass Actually Means

True grain-to-glass distilleries like True Theory Spirits do things differently. We:

  • Source our own grain — 100% Ontario winter wheat from local farms
  • Mill and mash on-site — converting grain starches to fermentable sugars
  • Ferment in-house — developing unique flavor profiles during fermentation
  • Distill from scratch — running our own copper stills, not just redistilling purchased alcohol
  • Control every step — from raw ingredient to finished bottle

Why Does It Matter?

Quality you can taste. When you control every step, you control the quality. Our True Theory Vodka has earned 174 five-star reviews on LCBO because customers can taste the difference.

Supporting local farmers. Grain-to-glass means real relationships with Ontario grain producers. When you buy True Theory, you're supporting Ontario agriculture.

Transparency. We have nothing to hide. We're proud of how we make our spirits and invite anyone to visit our Etobicoke distillery to see the process firsthand.

True craft. The word "craft" should mean something. Grain-to-glass is the standard that separates true craft distilleries from sophisticated bottling operations.

How to Spot a True Grain-to-Glass Distillery

Ask these questions:

  1. 1.Where do you source your grain?
  2. 2.Do you distill on-site or purchase NGS?
  3. 3.Can I tour your production facility?

A true grain-to-glass distillery will answer all three proudly.
