I'm making a holiday spiced beer today, the spices are fresh ground and the wort volume is 5 gallons. I was thinking of adding 1/4 tsp cloves, 1/4 tsp ginger, and 1 tsp cinnamon at 3 minutes left in the boil. I've never used spices before, and my target OG is 1.065-1.070. does this sound ok to you guys? I am looking to be able to taste the spices somewhat subtly, definitely nothing too overpowering.
