Matthew - thats only a 70% OG:BU ratio, so theres definately room for more IBU's if thats what youre wanting, for a pale ale I usually go 75% plus anywhere up to 100% :o) It wont be too bitter, unless youre a pussy ;oP hahaha
To work out the OG:BU ratio divide the IBU by the last two numbers on the gravity
So 38 divided by 54, times 100 is roughly around 70%
I generally aim for a specific OG, then times it by whatever OG:BU percentage im going for! Its a really handy calculation I reckon, I dont ever brew a recipe without it...
Mr Cherry's a known fruit beer brewer. He even puts coconut in his porters. Don't listen to him.
Sauvin is a sweet hop and I know that the kolsch malt (from tasting Jokings 1005 kolsch pale ale) is gutsy enough to carry big hop character. So, assuming you are not playing around your soft water, I'd leave the recipe basically as it is but just bump the ibu up a shade (maybe 45). Beers using strong sauvin character must be bitter - this year's Three Boys Golden is a good example. Would love to know the anticipated IBU's of that beer but Ralph's not known for giving away secrets.
I'm sure you'll be more disappointed if the beer is not bitter enough than you will be if it is too bitter (that ain't going to happen, especially with this hop).
I just did a very similar recipe to this that I learnt from JT. However, my goal now is to make the flavour of the beer a bit more citrus like. (A flavour similar to Sierra Nevada Pale Ale.) I would like your opinions...
94% Pilsner
6% Caramalt
12 gm Casacade 60 Min
12 gm Cascade 30 Min
12 gm Cascade 15 Min
30 gm Cascade 0
Dry Hop Cascade 12 gm in Secondary.
Do you think this will head me in the right direction similar to Sierra Nevada Pale Ale?
If youre looking for something similair to Sierra Nevada Michael id suggest Pearle hops at 30 and possibly 15 mins as thats what they use for flavour, then they throw a bucket load of cascade in at 0 and probably dry - which brings my next question, US or NZ cascade??
If its US cascade, up the 0 min addition to 50gms and youll be more in the ballpark, and up the dry hops to at least 30gms IMO...
If its NZ cascade, which can be a bit more offensive in higher amounts (again IMO) so your hopping looks about right...
