Im going to make a barley wine with all RO water Wed. for the first time. I brew allgrain biab.mashing with 9.5 gal. for a 5 gal. batch. 18lb. Maris otter base, 1 lb. honey malt,.5lb. C-120 and.25lb. C-60. I have calcium cloride, gypsum and acid malt. Ill be using real honey at flame out and figs and raisins in secondary if that matters. Would I need any acid malt or gypsum with that grain bill?
