True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.

Soft drinks from Eastern Thrace, Turkey
Hardaliye is a red, lightly pungent grape drink from Thrace. Crushed red grapes with their skins and seeds are layered in a vat with sour cherry leaves and crushed mustard seed, fermented by lactic bacteria for several weeks, then settled and drawn off clear. Made in 5 steps over 13 months – 14 months. The longest step, bottle and keep cold, takes up to 12 months (Turkish Patent and Trademark Office 2017) and runs at 5–10 °C (Turkish Patent and Trademark Office 2017). Lacticaseibacillus paracasei subsp. paracasei and Lactobacillus casei subsp. pseudoplantarum, which dominate a succession of lactobacilli does most of the fermenting.

Hardaliye is grape juice fermented by lactic bacteria rather than yeast. Crushed mustard seed and sour cherry leaves layered through the pomace set it apart from wine and from plain grape şıra.
Fresh hardaliye is perishable. Keep it cold (the GI specification gives 5–10 °C storage and at most one year at 4–5 °C). No coliforms or E. coli were found in 26 market samples at pH 3.21–3.97.
Every number is labelled with how it is known. How this atlas is made
The GI record says hardaliye was made in Kırklareli at the grape harvest as a traditional way to keep grape must from turning to wine. Kırklareli Hardaliyesi was registered as a Turkish geographical indication in 2017, with protection from 2013.
