I didn't make that one but I did make the Midwest Supplies Raspberry Red Ale last year. It was good.....for a fruit beer. It was for the gf and her friends. They really liked it. She wanted to try that after drinking Darkhorse' Raspberry Red Ale. It was my own concoction.
I only used 1 tablespoon of the extract but I used 2 lbs. of frozen raspberries and almost 2 lbs of black berries. I sanitized with about 1/2 cup of vodka then strained out the liquor and shoved them through the funnel into the carboy for the 3rd week of fermentation. It had a pinkish violet hue and smelled pretty good a week later. I would do that one again but all-grain.
After reading as many fruit beer threads I could, I decided against using much of the extract because people said it tasted like cough syrup. I have no experience with puree. One thing I would caution against, is using fruit with added sugar in it
Within the next day or two, I'm going to bottle up a strawberry blond that I concocted from BM's Centennial Blond. That one contains 3 lbs. frozen Costco strawberries and no extract. It has a very subtle flavor.
Read this one.
If you are not in a hurry, then read as much as you can.
