Nayuki's Harry Potter collaboration Halloween limited blood orange grapefruit drink draws consumer complaints over the bitter taste of grapefruit peel

During Halloween, major tea beverage brands have rolled out holiday-exclusive drinks to compete for young consumers.

Fans reported that the drink gets more bitter the more they sip, with some describing it as "more bitter than Americano." Nayuki staff explained that the grapefruit peel is kept to show the use of real ingredients, and advised drinking it as soon as possible or picking out the peel oneself.

Luckin's Pomelo C Series is hailed as a fat-burning miracle, but testing shows that although its calories are low, it raises blood sugar fairly quickly, so those trying to lose fat should be cautious.

After the Luckin Yuzu C series returned, it quickly became popular, and many people on social platforms have hailed it as a "fat-flushing miracle," with claims even circulating that "one cup can make you lose two jin." However, actual test data show that although a single cup of the Yuzu C series contains about 105 to 150 calories, blood sugar rises fairly quickly after drinking it, and the blood sugar increase of Yuzu C Iced Tea can reach 5.1 half an hour after a meal.
