Create a yeast starter with 1 C. orange juice, 1 tspn Yeast Nutrient, and Yeast in a mason jar. Let sit for 3-5 hours before brewing.
Crash the brew with 1/2 tspn per gallon of Potassium Sorbate after 7-10 days in fermentation, around when the OG reaches 1.020. Then, let sit for the rest of a full month to absorb the spices before racking to secondary. You can also pitch the spices in secondary instead, and rack immediately to secondary at 7 days.
On secondary, boil the the extra sugars for 15 minutes in a liter of water in a small sauce pot, siphoning off any nastiness. Pitch in, and give the mead a gentle stir for 30 seconds. This must be done after the Potassium Sorbate has been pitched and integrated well to crash the fermentation.
Be sparring with the orange juice. It tends to overwhelm the subtlety of the spices if too much is used, even by a half-cup. It adds a necessary acidic-sweetness to the mead to blend out the stark dryness of the spices against the earthy sweetness of the mead.
I tend to use a forest honey for a more mature vegetable sweetness, but summer bloom or clover works just as well.
Let sit on Secondary for 2-3 months. Continue to rack to desired clarity. Best if brewed in December and given at least 2 months to rest in a bottle.
