Hi,
I have so far only brewed all grain, but today I wanted to knock something out quickly so I decided to to a small batch using DME (12L batch using 2kg light DME).
When I was formulating my recipe, I noticed that a "normal" amount of bittering hops didn't give me anywhere near the IBUs I was looking for. Secondly, when i moved the batch size to 23L, it gave me a much more expected IBU figure.
Can someone explain what's happening here? I'm probably missing some fundamental point re: utilisation, but I'd love to understand what's happening.
Here is my recipe for reference:
2kg Light DME
30g Bravo (60min, 15.8%AA)
20g Cascade (10min, 8%AA)
15g Cascade (W/P, 8%AA)
With the batch size set to 12L, Beersmith gives me 17.8 IBU, but when I set it to 23L, it gives me 54.8 IBU.
Cheers!
