Harvest Tips
Peppers can be harvested at dark green stage for peppery flavor or allowed to fully mature to deep purple-black for sweeter, more complex flavor (7-10 days more). Cut peppers with pruning shears rather than pulling to avoid damaging the plant. Harvest regularly to encourage continuous production. Mature peppers store 1-2 weeks at room temperature or up to 2 weeks refrigerated.
Fun Facts
- 🌱 Peppery Shiraz peppers get their name from the Shiraz wine grape, and like wine grapes, the peppers develop increasingly complex flavor as they mature from green to deep purple-black.
- 🌱 The dark purple-black color comes from anthocyanins, the same antioxidant compounds found in blueberries and red wine, making these ornamental peppers nutritionally interesting.
- 🌱 These peppers are technically berries botanically speaking, and a single plant can produce 20-50+ peppers in a season when properly cared for.
