Zythos Session APA

My plan here was to brew an APA/IPA with a lower ABV (around 4%) but tasting like a full-bodied tasty pale ale. I found a recipe on Brewer’s Coop that looked in line with what I had in mind so I went with it for the malt bill and used 200g of Zythos American hops blend and picked Mangrove Jack’s M15 – Empire Ale yeast for it’s lower attenuation. Being a recipe for a lower ABV beer, the grain bill is on the small side but features more flavoursome malts – Maris Otter, German Vienna and Munich malts, light crystal. Also included is half a kilo of flaked oats to add body and texture. I mashed high to help keep the finishing gravity on the higher side and leave more body with less alcohol production.

3/4 of the hops went in after flame-out. Because I’m doing a pressure ferment in the Fermzilla, I decided not to do any dry hops addition, Instead I did a ‘cube addition’, So the post flame=out hops were divided into 3 addition – right after flame-out, whirlpool addition after 10 mins hops rest followed by another 10 mins hops rest and finally the ‘cube addition’.

Tasting notes

Light but good. Tasted more like a 5%er than a sub 4% beer.
