Single Hop Galaxy AIPA recipe check please!

I want to make a massive hop bomb! Gonna try Galaxy purely as I'm into astronomy(why not?)
Anyway, its a 15l batch, I'm copying the malt bill that Stone uses in its IPA (I'm adding 0.5% Choc just to darken it a little) and 200g of Galaxy!

Does this recipe seem ok then?

Galaxy can be very bitter, although it does mellow in time. I love the hop but never used that sort of amount.

Speak to Growling dog, he used a kilo in a beer once lol.

I had read about the bitterness - thats one of the reasons why Im not doing a 60 min addition, I though it might be a bit mellower if done at the 20min stage

Slight change - upped the batch size to take account of losses due to trub! And split the crystal between light and medium, as well as adding a little Munich.....

I personally would omit the crystal and chocolate altogether. I find galaxy has a very stone-fruit, juicy flavour to it anyway, which gives off the semblance of sweetness and so I don't think you'll have any issues in that area (if I recall correctly, Stone Ruination 2.0 has also made a similar shift of removing crystal).

For me (and your mileage may vary) with 200g of hops, I've been saving much of mine for the dry hop. And so I would maybe look to up the dry hop to 100g, although this may mean you require another hop just for a first-wort bittering addition

But that's just my 2 cents! It's always a wonderful hop, very rich in flavour

Here is my latest grain bill.... Added some Munich so there is hopefully still some hint of maltiness and split the crystal between dextrine and medium, to add some body and just a little sweetness....
