VERY STRONG drink - Similar to Long Island Iced Tea, but tastes much better to me, you don't taste the alcohol. You can adjust orange juice amount to adjust taste. Remember DO NOT drink and drive... This is a VERY strong drink but you don't taste the alcohol... fruity taste.
Don't use 3.2% alcohol beer - real beer is best - Budweiser(R) or similar.
I usually make a pitcher at a time in the summer. Use 4 to 5 ounces of each liquor, 16 ounces beer then add in orange juice until pitcher is 3/4 full then pour in grenadine until a dark reddish pink color. Top off remaining pitcher with orange juice.
