I'm planning to brew a saison inspired by La Vermontoise. I'm going to harvest the yeast from a bottle and make a recipe using Brazilian pilsen malt and Brazilian hops, Magnum for bitterness and Comet for flavor and aroma to brew with local ingredients. I know that La Vermontoise is made with a large late addition of Amarillo, no dry hopping, and have a nice hoppy aroma, even when the bottle gets older. I almost always add all my hops during the hot side and usually get low hop aroma that fades after a few weeks in my beers even with relatively large amounts in late boil or flameout additions. Any tips to get the same amount of aroma?
