On most lists of products containing estrogen, animal products like milk and beef are at the very bottom. Milk, for example, is said to provide 1.2 micrograms of estrogen per 100 grams.
Depends on where you go to get your fix. Starbucks Cold Brew (in stores nationwide since May 2015) and Dunkin' Donuts Cold Brew (in stores nationwide since August 2016) retail for different prices. Cost: Roughly $0.20 per ounce. $3.25 for a grande (16 fluid ounces) according to Starbucks.
So all in all, it cost me $18 for 2 gallons of cold brew coffee, (Starbucks charges $3.25 for a venti cold brew which is 20oz so doing the math in my head, that is roughly $40 if you bought the coffee).
