Bulk priming vs putting a measure of sugar into each bottle is debated by some home brewers:
Advantage of bulk priming :
- Even amount of sugar in the brew regardless of bottle size
- You can prime with dextrose or malt which is too messy and fizzy for spooning into individual bottles.
- Quicker? Thats debatable..Less fiddly, that's for sure.
- Get all the beer off the yeast cake in one go so your last bottles are not "scraping the bottom of the barrel".
- Risk of aerating the beer.
- Risk of contaminating beer.
bottom fill the 20 litre cube right to the top so that:
- Beer is not aerated
- Close the cap and tap on the cube once its full and it can be gently inverted to ensure good sugar mixing.
- Can be moved to a convenient bottling location without risking stirring up the yeast.
- Only the inside of your transfer tube need be sanitized.
- Cubes are easy to sanitize by shaking a bit of sanitizer around inside it.
- I put 180 grams of dextrose(glucose) boiled in 500ml of water into the cube first.
- Make sure you brew a little over 20 litres of beer.
- I used a "food grade" water hose from a boat equipment company (Whitworths in Australia)
- Tissue over airlock hole to reduce dust sucking in.
- The tap on the cube was slightly rotated up while filling and it didn't seem to affect the seal.
P. S - I now think 180g of dextrose is too much. I haven't tested it but 100g would be better. Will update how it turns out later.
