Last year we had an idea to make a lilac blonde ale using the lilac tree in Andy’s garden. It didn’t go as planned because just when the flowers were starting to come out we had a hot spell and the lack of water caused the flowers to be rather stunted. Instead we made Blackbeery Blonde (which incidentally, is drinking very nicely now it has had plenty of time in the bottle).
So here we are again – it’s lilac harvest time. We’ve had some nice weather over the last few days (although not a hot spell like last year) and so the tree was coming out nicely. We brewed yesterday, so of course it decided to absolutely tip it down just when we were cutting the blooms. But we ended up with a huge box full of (wet) lilac flower heads and a tree that looked no different, so many flowers were there on it.
The recipe is based on Jamil Zainasheff’s Belgian Blonde Ale recipe (called “Lefty Blond”, so you can draw your own conclusions as to which beer it is cloning). To that we added 846g of lilac flowers. Having read recipes for lilac wine, we were careful to ensure that there were no green bits left at all. It took us a couple of hours, during the mash and boil, to pull all the flowers off. Why 846g exactly? Because that’s where we just got completely sick of the task!
Then we agonised about when to add the flowers. The lilac wine recipes make a “lilac tea”, which involves pouring boiling water over the flowers and leaving them to steep for 24 hours. We, of course, have a vat of boiling wort which can extract the flavour and sterilise the flowers at the same time. We’d initially thought to add the flowers for the last two minutes, but having read the lilac wine recipes we decided to make it ten minutes. Hopefully that will have extracted enough flavour without killing the aroma too much. Interestingly, after pulling all the flower heads off my hands were a little resinous, kind of like after you have rubbed hops on your hands. Flavour oils?
