AHA member Marshall Bishop loves Tree House Julius so much that he has devoted untold hours to developing a faithful homebrew clone, the recipe for which he has kindly shared with us. Marshall offers helpful advice for brewing this recipe.

Water chemistry, a specific combination of yeasts, plus acids and essential oils from the hops combine to give this beer its hazy appearance. Tree House doesn’t use flaked grains.

Minimizing calcium in the brewing water contributes a soft mouthfeel. Hard water ions such as magnesium and calcium can contribute chalky, thick sensations – if you want softness in a beer, start with soft water. Using canning salt (sodium chloride) provides chloride without adding calcium.

The long whirlpool at 108°F (42°C) extracts and retains volatile hop flavor and aroma compounds that would otherwise evaporate at higher temperatures. You can replace the whirlpool with a hop stand to maximize contact between hops and wort, but you will get the best utilization from constantly stirring during whirlpool.

Dried yeast has sufficient sterols for healthy fermentation, so there’s no need to aerate or oxygenate. You want to stress the yeast enough to encourage ester production. Esters and other complex fruity, yeast-derived flavors match perfectly with the hop-derived fruity flavors and aromas. Resist the temptation to round up the specified quantities of WB-06 and T-58 if you can’t measure less than one gram, as these will dominate the clean strain and add too much farmhouse character.

Pitching warm and then cooling the fermentation encourages ester production while retaining volatile aromatic compounds. You still want some yeast activity when adding the dry hops, more to prevent oxidation than for any biotransformation mumbo jumbo.

Dry hopping in a mesh bag is not recommended. You’ll get better wort contact by letting the pellet hops dissolve and float free in the primary. Cold crashing won’t clear the beer of hop/polyphenol haze, but it will settle yeast.

Directions:

Mash at 156°F (69°C) for one hour, adjusting pH to 5.2 with citric acid if necessary. Mash out at 168°F (76°C). Fly sparge at 168-170°F (76-77°C). Don’t use Whirlfloc or Irish moss in the boil. Chill to 108°F (42°C) and add whirlpool hops, stirring or whirlpooling to keep hops in suspension for 60 minutes. Chill to 70°F (21°C) and pitch dry yeast blend; do not pitch more WB-06 and T-58 than specified, as they will dominate the clean base strain. There is no need to hydrate the dry yeast prior to pitching and no need to aerate or oxygenate the wort. After 24 hours, lower fermentation temperature gradually to 64°F (18°C) over a 60-hour period, let fermentation run at 64° F for 4-5 days depending on yeast activity, and then add the dry hops to primary and ferment to completion (usually about 2 days). Take care to minimize oxygen uptake at all times after fermentation. Cold crash to 32°F (0°C) for 2 days, then closed-transfer to a keg and force carbonate.
