- Breiss Caramel 120L, 1/2 lb.

- fresh ground ivy (gill-over-the-ground, alehoof, etc.: Glechoma hederacea) leaves and flowers, 1 packed quart

Add honey and bring to a boil. Put coriander and juniper into a nylon bag and add during last ten minutes of boil along with remaining herbs. Add tea at beginning of cooling process. Pitch yeast at 80F. Put nylon bag into fermenter and let remain until bottling. Bottle after ten days and age for two weeks.
This was very interesting, but I personally would’ve preferred something bitterer. I’ve never found ground ivy to be anywhere near as bitter as the books say, but it could be the wild stuff I use tastes different from British or cultivated varieties. I was anxious to avoid the turpentine flavors often found in spruce beer, but needn’t have worried — it was virtually unnoticeable. My friend the sustainable brewing expert Chris O’Brien detected a bubblegumish ester, a German wheat beer flavor which he likes (and felt there could’ve been more of). Rachel Rawlins, who assisted in the brewing — and documented it in photos — blogged some detailed tasting notes.
We took our task seriously, beginning with appearance. “Amber”, we agreed. A reddish beer with a small head (at least once the excessive zeal had been tempered). B2 rated the aroma as “spicy”, I went for “medicinal” since, even through the lingering head cold, I detected the faint presence of the memory of the previous brew’s sassafras.
Mouth-taste had us trading words like “citrus”, “bitter”, “leafy” and “aromatic”. B2 noted that it was “not too fizzy”. But it was trying to define the lingering after-taste that proved most challenging.
In the end I went for “resinous”, probably because I knew there was spruce in it. B2 professed to be unable to think of anything. It was, he said, unlike anything he’d ever tasted before. “Well”, I prompted, “is there anything that it reminds you of, however distantly?” He paused for thought. “Concrete.” “Concrete? You think it tastes like concrete? But what does concrete taste like?” “I don’t know. That’s why I said it.”
And now the last mouthful is gone. Goodbye, resinous concrete – a unique and delicious brew.
