For distilling, you don't set a fixed temperature the same way you would for brewing — instead, the G30 has a dedicated Boil Power Mode that gives you direct control over power output, which is what actually matters during a spirit run.
Before you start: check it's legal where you are
Distilling laws vary significantly by country, and this isn't legal advice — always check with your local authorities before distilling.
How to enable Boil Power Mode
- Hold the heat button for 6 seconds to activate it.
- The LCD switches from showing your usual temperature target to showing current temperature and power output instead.
- Use the up/down buttons to adjust power in 5% increments.
- To exit, hold the heat button for another 6 seconds.
Why this matters for distilling
Lowering the power output slows the rate at which distillate comes out — handy control to have during the spirit run when you're separating your cuts:
- Foreshots: the very first distillate off the still — can contain methanol and should never be consumed. If you require any advice on this, please get in touch with our customer service team before continuing.
- Heads: come off next, fruity/ester character — not usually consumed directly, but can be saved for blending or added to future runs to improve yield.
- Hearts: the main event — the best-tasting, best-quality part of the run, and what you're aiming to collect.
- Tails: the last portion — heavier alcohols, more water, generally unwanted.
Recommended starting point
- Bring the G30 to a boil first.
- Switch into Boil Power Mode.
- Around 80% power tends to be the sweet spot for most distilling runs — nudge it up or down depending on how fast or slow you want the run to go.
A note on cooling
If you increase the power, you'll need more cold water flowing through your condenser to compensate — this keeps your temp probe reading within the correct range for distilling. More power in means more cooling needed to match it.
