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.
I cannot stress enough that this is retail cost of us making Starbucks at home, just look at how cheap it is for us to make it at home. imagine the cost of that $14.95/1lb roast for Starbucks probably going down to about $1 or less per pound.
