Just put together a RIS ( first ) And have to say I found it a real challenge.
I do not have the rolls Royce of brewing equipment as I believe home brewing should be kept simple and cost effective. I guess if you have the money though go all out. LOL. I managed a OG of 1.105 with grain only and in a 30ltr mash tun . had 1 ltr of space left. done a mash schedual of 15min @ 52 , 70 min @ 68 and 20 @ 76 . My grain to water ratio was 2.6ltr-1kg .
I have to say though that I had very little sparge water 9.4ltr. was very happy with my efficiency 87 % got 21ltr into the fermentor. I used WLP500 ( trappist ale ) Made a 2 step starter fist step 3ltr then decant and a 2 ltr 2nd starter then decant and cold pitch slurry. Oxygenated with O2 for 5min before pitching and plan on leaving in primary for 3 weeks then move to secondary for 8 weeks . Bottle condition until this time next year.
I use gelatine to clear my beers in the secondary before bottling with good results . Just takes a little longer to carbonate my beers. but have read a that a lot of people use yeast again before bottling a RIS not sure if this is necessary ??? but would like to know what others that have made these have found with theirs ?
