I approach brewing from exactly the opposite direction, price being the last thing I am concerned about, the quality of the beer being the first, second and third!
Let’s look at the real cost of home brewing; you can break it down into ingredients and process costs.
Your process cost won’t change much, the first and biggest is your time; realistically the total time committed to a brew is going to be around 6-8 hours by the time you add in all the actual brewing, planning, cleaning and packaging time – I don’t know about you but that time has a real value to me.
Energy and water both cost as does cleaning chemicals, bottle tops or CO2 if you keg, running a couple of extra fridges it all adds up and most brewers pretend it’s all free, it isn’t and it’s worth remembering.
I’ll leave it to you to assign a value to the process cost, I don’t want to drag this thread totally off topic which putting any number larger than the cost of the LPG burned or electricity used would do.
Ingredients, well to my mind you just buy what will do the job best.
In short if you wanted to make and ESB you would use English Base Malt and some UK Crustal and East Kent Golding’s and a top English yeast, and OK Australian water. The beer could be referred to as being made from local and imported ingredients.
If you sat down and worked out the cheapest possible recipe that hit the same specs and compared it to a recipe using the finest ingredients available I doubt there would be $10-$15 difference on a 23L batch.
In fact as an exercise I just went into my (now defunct) retail store and costed two versions of Fullers ESB using the same yeast, which really is the best choice, the difference was about $10, about $15 if you chose a dry yeast over a liquid.
For that $10 across 60 Schooners we are talking and extra 16 cents a schooner and I can absolutely guarantee that the one made from premium ingredients would taste a lot better, for me to worry about 16c/Schooner when you realise that the real cost of brewing is much higher than the ingredients is – well frankly it’s nuts.
As a starting out brewer, first up learn to brew, learn how to make quality beer you enjoy. Buy your ingredients from a reputable retailer who looks after their ingredients and offers a good range. Use a well tested recipe that is known to make a faithful example of the style of beer you are wanting.
If the cost is more important than the quality you probably need AA more than you need AHB
