Mangrove Jacks M36 Liberty Bell Ale Yeast 10g

M36 is a versatile American ale yeast with a clean fermentation profile and a touch more body than a purely neutral strain. It suits the broad range of American ales where you want clean character without the complete neutrality of a West Coast yeast — a small amount of fruity roundness that supports the malt without dominating.

Best Suited To

• American Pale Ale, American Amber Ale, Red Ale
• American IPA, Cream Ale, Blonde Ale, American Brown Ale
• Australian pale ales where American character with a little more body is the goal

Specs

• Fermentation temp: 18–23°C
• Attenuation: 71–75%
• Flocculation: Medium-High
• Alcohol tolerance: Up to 12% ABV
• Pitching rate: 1 sachet per 23L at standard gravity

When to Choose M36

Choose M36 over M44 when you want a slightly softer, more balanced beer rather than maximum dryness. M44 attenuates more aggressively and emphasises hop character; M36 leaves a touch more body and is a better fit when the malt bill needs support.

Choose M36 over M15 when you want American rather than English character. M15 is expressly British in its ester profile; M36 is clean with only a subtle fruit note that suits American styles.

Practical Notes

The subtle fruit note is most noticeable at the upper end of the temperature range (22–23°C). Ferment at 18–20°C for a cleaner result where the slight body is retained but ester character is minimal.

Rehydrate in 10x its weight in 27°C water, or pitch directly at fermentation temperature. Works well for all standard-gravity American ales without nutrient supplementation.

Keep refrigerated. Once opened, reseal and use within 7 days.
