Codename : Mountain Portage Best Bitterthorpe (2025)
This specific recipe started as a happy accident back in 2022, and it turned out so well, I have kept it going with great success, really only adjusting the recipe slightly for the hops and yeast I have in stock.
More evident malt flavour than in an ordinary bitter; this is a stronger, session-strength ale.
Ingredients
- 11 oz Maris Otter (1.8L)
- 8 oz light Munich malt (6.9L)
- 4 oz Amber malt I (27.9L)
- 3 oz Light Crystal malt (39.4)
- 1/4 Campden tablet when preparing strike water (optional)
- 0.1 oz Lumberjack hops at 30 minutes
- 0.2 oz Minstel hops at 20 minutes
- 1/4 tsp Irish Moss (optional) at 15 minutes
- 0.2 oz Willamette hops at 5 minutes
- 3 ml Windsor dry ale yeast

Brew Day
- Prepare 4.5L strike water at 152F.
- Add the milled grains to the bag.
- Place the bag in the hot water, set the timer for 90 minutes, and maintain the temperature at 152F.
- It is acceptable if the temperature varies a little.
- Stir occasionally.
- With approximately 15 minutes remaining, heat 2L of sparge water to 170F.
- Calibrate the refractometer, aka the sonic screwdriver.
- Lift the bag out of the water, and allow it to drip into the pot. Every bit of sugar that can be extracted will benefit the end ABV.
- Pour the sparge water over over the grain bag, this should help extract even more sugar
- Bring up to a boil, 212F, set the timer for 30 minutes. Add hops, and Irish moss, as prescribed above.
- Sanitise everything required for fermentation.
- Cool to room temp, an ice-bath or a snowbank work effectively.
- Prepare the yeast mixture.
- Pitch the yeast to the carboy.
- Transfer the wort to the carboy, splash the wort around to aerate the contents.
- Put the airlock on the carboy.
- Store in a cool dark place for primary fermentation for 7 days.
Bottling Day
- Detailed instructions.
- Prepare 0.7 oz corn sugar.
- Bottle condition at least 4 weeks.
Brew Notes
- This recipe was adjusted on the fly, as in by the time the boil was to start, I had achieved the post-boil gravity, so the sugar I was going to add, was withheld.
- This sparging routine seems to have increased my BHE by 5%, so I will use 75% going forward.
