Phantasm - 100 g

Phantasm is the original Thiol Precursor Product, derived from block specific Marlborough Sauvignon Blanc Grapes and is rich in Cysteine and Glutathione bound Thiol Precursors, which in the right fermentation conditions will unlock into the Free Thiols 3SH and 3SHA.

Cysteine bound Precursors are more available for yeast to convert than Glutathione bound, so there is no benefit to adding it in the mash. Hops on the other hand have smaller amounts of Glutathione bound precursors, and a mash hop addition will help convert them to the Cysteine form before final conversion during fermentation.

We recommend that you add Phantasm during the Whirlpool and dose between anywhere from 4 – 12g/l depending on your goals, with 6g/l a nice sweet spot. Keep in mind that there will be a touch of fermentables with Phantasm (0.3P bump on average), and it will drop your pH slightly.

Phantasm is not a hop replacement, but it will amplify the thiol release from hops fermented alongside it and it will work across a range of styles, and we see good results from IPAs through to Lagers. Hops such as Motueka, Citra, Nelson Sauvin, and Simcoe will work well in dry hop, but also feel free to experiment!

Store Phantasm like you would hops. Keep it cold and oxygen out. The precursors will only degrade after sustained 40°C heat, but we think cold storage is still a good practice.
