This stuff tastes very strong. It took a lot of effort for me to drink without making a sour face. Some Chinese will spike their beer (I liked Chinese beer) with baijiu.
I'm native Chinese, and I never see people spike beer with baijiu over the last 20 years in China. I'm not sure it's how ABC (American Born Chinese) drink baijiu in America.
Some friends and I bought a nondescript looking, average-priced baijiu from a liquor store while we traveled in China. I would describe the taste like one part everclear and one part shitty homemade mead, steeped together with toenail clippings. I spat it onto the floor and dry heaved.
That was five years ago and I still feel queasy thinking about it. It will likely be another decade before I could stomach trying it again.
