Later today I will be starting a kit cider, which will eventually become raspberry-infused. I think I must have read just about every post relating to raspberry ale on the forums, and it would be fair to say that the best results are going to be from the fruit & juice addition in secondary. The question is, how does one establish the final ABV, considering that fermentables are going to be added between the end of primary and the start of secondary. Here's the scenario, for the number-crunchers out there:
Primary to 18, then 20litres:
So if the OG is taken before pitching, then again at day three after 2 litres of juice is gently stirred in, then a new OG reading after racking to secondary and the second juice with raspberries is added, how does one calculate the true OG for the purposes of establishing ABV? Is it as simple as adding the point variance at stage 2 & 3 to the pre-pitching reading..... I suspect it's probably a bit more complicated than that... ... ...

Primary to 18, then 20litres:
- 1.7kg kit can of cider (Black Rock)
- 1kg plain white sugar
- 250grams Dextrose (for a bit more of a kick!)
- Top up to 18 litres
- Kit yeast (why bother with an ale yest, right)
- Yeast Nutrient (iether the kit pack or a teaspoon of Brewcraft nutrient salts)
- After three days, 2litres of apple juice added to fermenter, topping up to 20 litres
- Rack after 7 days from pitching
- Another 2 litres preservative-free apple juice
- 1kg raspberries, strained, the 'tea' added to fermenter
- Residual pulp in a muslin bag, and added to fermenter
- Prime and bottle after 7 days in secondary
