About a year and a half ago i did a partigyle brew. Original batch was a RIS, and I was going for a RIS in the partigyle. I did a continuously hopped RIS for 120 minute boil. Aged on french oak for about 2 months. End result is about 1/2 to 2/3 of a gallon. Somewhere between 13-18%. Did some calculations and figure ill need somewhere between 1.5-2.0 grams of priming sugar. My question is how much water should i use to boil the sugar in? Or if anyone has had any experience in a similar situation it would be greatly appreciated. Thanks in advance!
