Welcome to The Forum!
In answer to your question "Amazingly high!" However, whether anyone would want to pay money to buy it or even want to drink it is equally "Amazingly low."
Just a few numbers for you to consider:
- There are 100+ types of yeast.
- The yeasts function over +/- a 15*C range of temperature.
- There are 150+ different types of malt.
- The malt can be Mashed at various temperatures for various amounts of time.
- There are over 100 different types of hop.
- The hops can be added during the boil, after the boil, during fermentation or after fermentation.
- The minerals and pH of the water used can vary immensely.
- Etc etc etc
The numbers indicate that there are many millions of combinations (remember "Amazingly high"?) many of which will be totally undrinkable (remember "Amazingly low"?).
In brewing, the most difficult thing to achieve is not the production of an "original craft beer" it is the
consistent production of a palatable beer that is liked by many people.
This may look like a put-down but it isn't.
I encourage anyone who wishes to start brewing beer to
"Go for it!", with the proviso that you write down
everything that you do so that, when that
"perfect pint" arrives, you know how you managed to do it, can repeat the exercise and can look at producing and selling your very own
"original craft beer".
Enjoy!
