I usually make black and elder. Has anyone else noticed (or commented) that although wild blackberries are much smaller than cultivated ones, they have a much better, stronger, richer taste? It seems to me that cultivated blackberries have been developed for size and appearance only, and flavour is forgotten about. I only ever use wild ones. Collecting them is also more fun than shopping (and I won't waste time, garden space and effort growing them).
I usually try to make my B&E very slightly sparkling, simply by bottling it before it has completely finished fermenting. Care is needed, but using one (smallish) PET bottle permits squeeze tests to ensure all is OK, and I use screw-cap wine bottles just in case it isn't. You've got to leave it for quite a while to finish fermenting and clear, but as I'd leave it for a good while anyway, that's no problem. Chilled, it is gorgeous.
