Yuzu: Sources | World of Citrus

Summary from transcript: Weird Explorer tastes Yuzu bought in Hong Kong. The flesh is intensely sour with lemon-mandarin flavor and little bitterness; the peel tastes bitter but pleasant with sugar. He finds many seeds, makes a sweetened peel-and-juice drink, and discusses ponzu, preserves, tea, and traditional aromatic uses. A general 15°F survival claim is mentioned without a measured cold event. Cultural remedy claims are not treated as evidence of health benefits.

Summary from transcript: Business Insider visits Japanese and American Yuzu producers and interviews a chef about fragrance, freshness, and culinary uses. Growers describe thorn-related harvest damage, grafting to shorten the wait for fruit, greenhouse production on the US East Coast, and juice loss as ripe fruit ages. The 2025 report also discusses supply, prices, and import restrictions as reported at that time. Those trade claims are historical reporting, not current import guidance.

Summary from transcript: The Mulberries reviews Yuzu and Shekwasha purchased from Winterwarm Farms. Yuzu is reported at about 70 g and 12 °Brix, with many large seeds, medium-low juice yield, high acidity, low sweetness, and no detected bitterness. Its lemon-lime flavor and floral, honey-like, mandarin fragrance suit cooking, preserves, drinks, and liqueurs. The sampled rind is edible and not bitter. Shekwasha’s 12 g and 13 °Brix readings are separate. The presenter suggests brief cold tolerance around 5–10°F without documenting a freeze event.

Summary from transcript: The Mulberries tours Ichang papeda, Yuzu and related hybrids in Central North Carolina, Zone 8a. The grower compares vigor, foliage, winter damage and recovery, and discusses selecting seedlings for hardiness and fruit potential. Yuzu produces off-types across seed batches; Ten Degree Tangerine produces a small proportion of visibly different seedlings, including presumed trifoliate hybrids; Ichang Lemon also produces zygotic seedlings at a low, unquantified rate. Recent Yuzu × trifoliate and Ichang Lemon × Thomasville pollinations have set fruit, with hybrid offspring still anticipated. Reported seedling variation is based on grower observations rather than genetic testing.

The post discusses two distinct plants. Its author reports that their Yuzu was left outdoors over the previous winter, survived a stated coldest temperature of −8°C, but lost one branch estimated at 15–20% of the tree and the prior year's fruit during a two-week December freeze. A later comment says the 5-ft Yuzu was outdoors while smaller plants were kept in a small plastic greenhouse, and places the author on the Laois/Kilkenny border. The page showed only a relative date (“3y ago”); no exact calendar date, rootstock, accession, temperature method, or hourly exposure duration is given. This is Yuzu evidence, not Miyagawa evidence.

The study examined seedling populations from open-pollinated rootstock fruits collected in Adana, Türkiye. Two hundred seeds per rootstock type were sown and 100 seedlings per population were analyzed by flow cytometry. The authors report diploid genome sizes for all assessed populations. The study measured ploidy/genome size, not embryo origin or clonal identity, and does not establish a zygotic-seedling percentage.
