Bulk priming is a packaging habit, not a style. You boil a small sugar solution, cool it, and mix it through beer that has already reached a stable final gravity. Then you bottle from that single vessel. Each crown gets a similar chance to bottle condition. The heritage glossary listed the term because Australian club night Q&A kept repeating it. The path is /beer-glossary/Bulk-Priming/.
Why not dose bottles one by one
A dry teaspoon per bottle sounds rustic. It produces a mixed case: some bottles gush, some stay slack, some referment like grenades. Sugar tablets are more consistent than loose crystals and still sit behind a well-mixed bulk solution. Commercial breweries that bottle-condition use measured wort or sugar on a scale you will not see in a kitchen. Do not invent their grams here.
Priming is the parent idea — adding fermentable sugar to raise carbonation. Bulk priming is the even method.
The practical Australian Saturday
Sanitize the bottling bucket, the tap, and the wand. Rack the beer off trub if that is your process, or bottle from a fermenter that has settled. Mix the cooled syrup gently so you do not fold in air — aerobic oxidation at this stage stales a pale lager fast. Fill, crown, store warm enough for yeast to work, then cool. Summer sheds in Queensland overcarbonate if you forget them in 35 °C heat.
Use dextrose, sucrose, or dry malt extract with a calculator that matches your volume and target volumes of CO2. Styles differ: a British-leaning bitter wants less gas than a wheat beer. Homebrew basics holds the walking tour. Legal home production has limits. You may not sell the case.
What this is not
It is not a way to rescue a stuck ferment. It is not a flavour adjunct like vanilla. It is not required if you keg and force-gas. It will not print on a tap badge in Melbourne. ABV still matters more on a label than your priming spreadsheet.

One syrup, many even bottles
Bulk priming dissolves a measured sugar into the whole batch so each bottle gets a similar charge. It is how you avoid a mixed case of gushers and duds. Sanitize the bucket. Mix gently so you do not fold in air. Confirm gravity is finished. Then wait.
Priming is the parent idea. Bottle conditioning is the result. Keg force-gas skips both. Legal limits apply. We will not invent CO2 volumes for named commercial beers.

If half the case is lively and half is slack, you did not mix. Next time, one solution.
Even carbonation is a courtesy to your future self
Bulk priming is politeness in liquid form. One boiled syrup, cooled, mixed, bottled. Friends do not receive a random lottery. Sanitize the bucket. Do not splash. Confirm final gravity. Then wait.

If you are tired at midnight, still mix the syrup. The morning you is the person who opens the case.
Club-night packaging
A Melbourne club night that bottles ten pale ales from one bucket learns bulk priming in an hour. One syrup, one mix, ten even crowns. The person who spoons sugar into each bottle learns it the following weekend when half the case gushes. Sanitize the wand. Confirm final gravity. Store out of a hot shed. Homebrew basics is the walk-through. Legal limits apply. You may not sell the case. Cite the heritage path. This is beerguide.com.au. Eighteen and over. No invented volumes of CO2 for named commercial beers. If you keg next month, force-gas is allowed — priming is not a moral requirement.
Volume marks on the bucket
If you do not know the beer volume, the sugar charge is folklore. Mark the bucket. Weigh the sugar. Mix. This is beerguide.com.au. Homebrew basics. Legal limits apply.
One more cellar note
Weigh the syrup vessel before and after if your calculator and your kettle disagree. Arithmetic beats folklore. This is beerguide.com.au. Legal home production has limits.
