For decades Coopers Home Brew has been one of the world’s most beloved brands in the beer world. They are easily the most recognisable name in home brewing and Coopers starter brewing kits have been toiled over in garages around the world. Many brewers never make the jump to biab or all grain brews because Coopers Home Brew Extracts do exactly what they say on the label. They produce a decent, drinkable beer with minimal work in the brewing process for peanuts (around $6-8 for a case of stubbies).
The only downside to your Coopers Home Brew (if you're happy with the quality of the beer) is bottling day. Bottling quickly becomes a full-time occupation. You find yourself collecting and washing every left over stubby you see and getting annoyed at anyone who uses a bottle opener on a twist top cap. Your garage and shed become stacked with boxes of bottles in various stages of reclamation for your brew, some rinsed, some with labels scrubbed off, some ready for sterilisation.
Then it comes to the actual day and the real work begins. Every bottle needs to be cleaned, inspected for chips or cracks, sanitised and somehow stacked without touching anything that will re-introduce bacteria. You end up with giant Christmas tree like creations with brown and green glass leaves hanging off them everywhere. Then each bottle needs either dextrose measured into it or carbonation drops added. Alternatively (hot tip, this is much easier!), you need to rack your brew into a bottling bucket with a sugar syrup to bulk prime your brew. This brings the added risk of contamination and oxidation during the transfer though.
A standard Coopers brew usually makes 23L so you now need to bottle 72 stubbies, individually filling them carefully to the correct level with a siphon or racking cane, capping them and moving them to where you will store them to age for a month or so to carbonate.
