I used this recipe as a guideline and made a 5 gallon batch with 3 gallons of fresh peach cider (gravity of 1.035) and 2 gallons of wort. I pasteurized the cider for 10 mins at 160, let cool, then racked it onto the wort after the boil. I will add 2.5 pounds of peach puree to the primary after day 3 of fermentation, give it a few more days, then sorbate/sulfite it, then rack to secondary over another 2.5 lbs of puree to back sweeten. Here's what I used:
1/2 lb crystal 10L
1/2 lb crystal 40L - both steeped for 30 mins around 150
1 lb - light DME
3.3 lbs - amber LME
0.5 oz - 5.5% Mt.Hood
30 minute boil, used wort chiller, pitched Wyeast ESB 1968 last night around 1030, bubbling this morning at 7, forgot to get an OG. I plan on kegging after two weeks in the secondary. If additional sweetness is not needed, the second puree addition will be foregone. I'll let you know how it turns out.
