So, I strained the blackberry liqueur mash today. As you can see from the before and after pictures, with the berries and zest and all filtered out, the volume is somewhat decreased. It's still a bit cloudy, and I figure that's okay–I used a colander, cheesecloth, and a gold-mesh coffee filter. The next step would have been paper coffee filters, but that would have taken all day and to no great effect.
And how, you ask, does it taste?
Why, it's terrible! Awful stuff! Vile! If you come to my house, I wouldn't insult you by offering you any. You'd hate it. Really, you would.
