I'm gonna give rum a try but have a few questions
1. do you have a dedicated fermenter for rum? I'm worried about later putting a TPW for a neutral into a fermenter that had molasses in it
2. The sugar comes in 20kg bags and the molasses in 5 litre jugs. so 1/2 bag of golden sugar and 1 1/2 jugs molasses per batch.
Amount of fermentables looks ok?
In a 120 litre fermenter
10 kg golden sugar
7.5 litres blackstrap molasses
1/2 tsp epsom salts
220g bakers yeast
top up to 80 litres giving me 40 litres of head space in the fermenter for foam up. Should give me two 35-37 litre charges for the 50L boiler with the lees left for the other half of the bag of sugar and another 1 1/2 jugs of molasses!!!
My ferment room is cool, around 21' which is fine for my TPW's (takes a 2 1/2 week ferment time). Do you think this is a bit cool for rum and should I use an aquarium heater to up the wash temp? 26-28 degrees? I never use an airlock, just a loose fitting lid to let CO2 out
