Saison Achillea — Gruitbier inspired saison

Yarrow LifeGregory and I brewed this saison back in June 2015 and we ended up bottling a few gallons and kegging the rest.  Though we thoroughly enjoy hoppy beers, we also love brewing experimental hop-less brews that take their inspiration from historical beer styles and bygone brewing techniques.

The name Saison Achillea is a reference to the binomial name of the flowering plant widely known as common yarrow, Achillea Millefolium.  We used foraged yarrow as well as a small amount of foraged local lavender (another plant traditionally found in gruit) in the production of this beer and pitched our go to saison yeast, Wyeast 3711 French Saison.

Yarrow & LavenderYarrow has a varied history and mythology, including being revered as a healing herb and magical plant in ancient Greece.  In China, the I-Ching is traditionally cast with yarrow stalks which represent the Yin and Yang forces of the universe.  In Native America, yarrow was used as a medicinal herb by tribes across the continent.  In beer, yarrow imparts a sweet floral fragrance but acts as a bittering component and imparts tartness on the palate.  I consider this a sour beer, although we didn’t pitch any bacteria; all the tartness comes from the yarrow.

Tasting Notes — 11. 01.15 (poured from bottle)

This beer is quite clear now that it has had time to bottle condition for over four months.  The aroma is floral and herbal-sweet like tea with a hint of lavender.  Surprisingly, there’s not much in the way of spicy saison yeast phenolics or fruity esters (though I don’t recall if we utilized the brewbelt this time around).  The yarrow dominates the palate, starting as an herbal, sweeter ginger-like note before it melds into the malt backbone which is reminiscent of wild honey.  There is a hint of lavender sweetness before the yarrow returns to dry out the finish with some balancing astringency and acidic tartness that pierces the sides of the tongue and lingers on.
