Recipe called for 400g lactose. This upped to 500g. But still a little tart, and I wouldn't want more than one pint!
This could just be from using blackcurrants, which are fairly tart, to start with.
Next year, I'll try aiming for a bit more body, to balance the acidity. With more dextrins, from either a higher mash temperature, or adding some Cara malt.
Alternative might be to reduce the acidity (up the PH), by reducing the initial % of blackcurrants (with higher % later), or reducing the amount of Sucrose.
