I am a nut for farmhouse ales and IPAs. Only recently, I've decided to try and combine my obsessions and here are my thoughts:
- saison yeast work VERY WELL for IPAs. Most importantly, they are highly attenuative, which you want for any hop forward beer. THey also carry belgian esters. Depending on the yeast strain and hop profile you are going with, you can turn this into an advantage
- WY3711 would be one fo the best choices I would choose for a farmhouse IPA. Ridiculous attenuation, very clean finish, and a bit more subdued in its yeast presence. It has a prominent lemon flavor, which I find goes great with any typical IPA hops or new world fruity ones
- Keep in mind it may not technically be a "session" beer if you use a saison yeast. It will probably take it around 5 points lower than intended in the recipe based on using their clean ale yeast
- I add either wheat or rye to every single one of my saisons. It helps the body with the high attenuation. I'll do anywhere from 15% all the way up to 50% wheat/rye/oats/or flaked. Are you doing extract? If so, I would very strongly recommend some simple sugars to help dry it out as much as you can. I try to get all my farmhouse ales and all my IPAs below 1.010. This can be an issue with extract based beers
- I wouldnt add vienna. I dont think it would hurt it much, but I have NEVER found that you need to add certain malts to add "complexity" to IPAs or farmhouse ales. The complexity comes from the hops in IPAs, and the yeast in farmhouse ales. Anything else you try to cram in is only going to muddle the character you are trying to achieve
- If you are doing all-grain I would definitely mash lower. I mash all my belgians at 148, and my IPAs at 150. I might go 152 if I was doing a session IPA to try and keep more body, but usually I use more specialty malts for that purpose. Dont be afraid that it will come out too thin bodied, even with mashing low and using wy3711. This yeast creates a good deal of some sort of compound (dont remember the name of it) which is attributable to mouthfeel. Every saison I've made with WY3711, even ones that got below 1.000 FG, werent at all thin bodied. The main goal with a beer like this, IMO, is to get a super clean and crisp finish
