Here's a conversation I had. It's not perfect but I found it interesting.
Me: Can you give me a beer recipe in metric for 20l for 75%efficiency for a American amber ale?
Chat GPT: Sure, here is a recipe for a 20-liter American Amber Ale with a 75% efficiency:
Ingredients:
7.5 kg of 2-Row Pale Malt
0.5 kg of Crystal Malt 60L
0.5 kg of Crystal Malt 120L
0.25 kg of Caramel Malt 80L
0.25 kg of Caramel Malt 120L
40 g of Centennial Hops (for bittering)
20 g of Cascade Hops (for flavor)
20 g of Willamette Hops (for aroma)
1 package of American Ale Yeast (such as Wyeast 1056 or White Labs WLP001)
Water for brewing (around 20 liters)
Instructions:
Start by heating your brewing water to around 67°C (152°F).
While your water is heating, crush your malt and set it aside.
Once your water reaches the desired temperature, begin the mash by adding your malt to the water and stirring to ensure that the malt is fully hydrated.
Hold the mash at 65°C (149°F) for 60 minutes.
After the mash is complete, begin the lautering process by separating the liquid wort from the spent grains.
Once the wort has been separated, bring it to a boil.
Add your bittering hops (Centennial) to the boil at the start of the boil and your flavor hops (Cascade) after 15 minutes.
Add your aroma hops (Willamette) in the last 2 minutes of the boil.
After the boil is complete, cool the wort to around 21°C (70°F) and transfer it to your fermenter.
Add the yeast, and ferment at 21°C (70°F) for 7-10 days or until the fermentation is complete.
Once fermentation is complete, transfer the beer to a secondary fermenter or keg.
Carbonate the beer to around 2.5 volumes of CO2 and let it sit for at least a week before serving.
Enjoy your American Amber Ale!
Please note that this is a basic recipe
Me: what would you expect the flavor profile would be for this recipe?
Chat GPT: The flavor profile of this American Amber Ale recipe will depend on the specific malt and hop varieties used, as well as the yeast strain and fermentation conditions. However, in general, you can expect the following:
Malt: The malt bill for this recipe is composed mostly of 2-Row Pale malt, which will provide a clean and biscuity base for the beer. The Crystal malt 60L and 120L will add caramel and toffee notes to the beer, while Caramel malt 80L and 120L will contribute to a rich amber color and a subtle nutty and toffee flavor.
Hops: Centennial, Cascade and Willamette hops will provide a nice balance of bitterness and hop flavor/aroma. Centennial will provide a floral and citrusy aroma, Cascade will add a grapefruit and floral flavor and Willamette will bring a woody, earthy and herbal aroma.
Yeast: American Ale yeast will ferment cleanly, allowing the malt and hop character to shine through.
In general, you can expect this recipe to have a rich amber color, a medium body and a clean malt profile with a balance of sweetness and toffee notes, with a good balance of hop flavor and aroma, a moderate bitterness with a pleasant floral and citrusy aroma.
Keep in mind that these are general guidelines and the final product may vary depending on the specific ingredients you use and the brewing process conditions.
Me: Can you adjust this recipe to be more caramely? Ingredients only.
Chat GPT: Sure, here's a way to adjust the recipe to make it more caramelly:
Ingredients:
7.5 kg of 2-Row Pale Malt
0.5 kg of Crystal Malt 60L
0.5 kg of Crystal Malt 120L
0.5 kg of Caramel Malt 80L
0.5 kg of Caramel Malt 120L
40 g of Centennial Hops (for bittering)
20 g of Cascade Hops (for flavor)
20 g of Willamette Hops (for aroma)
1 package of American Ale Yeast (such as Wyeast 1056 or White Labs WLP001)
Water for brewing (around 20 liters)
In this version of the recipe, I've increased the amount of Caramel malt 80L and 120L, which will contribute more toffee, caramel and nutty notes to the beer, making it more caramelly.
It's important to keep in mind that this is just one way to adjust the recipe. You can also experiment with different types of caramel malt or even different types of crystal malt to achieve a different flavor profile. You may also want to adjust the hop amounts or types to suit your personal taste.
