Progress update:
Mashed 24 lbs plums and added 2 1/3 tsp pectic enzyme (all I have left apparently. Getting more tomorrow). Poured into paint straining bags I use as brew bags and zip tied. Made a simple syrup with 4.5 kg sugar and 9 liters water. Will mix when room temp along with 6 Camden tabs.
Plan to make yeast starter with my 71B tonight. Calculator tried to say I need 20 g yeast but I think I'll stick with 1g per gallon (6.5g). I'll top up sugar and water to my target volume and SG 1.095. Any tips are appreciated
