I ran out of beer to drink. I discovered that my Saisons taste way better with acid malt in. I remembered how good Tooti Fruiti (a sour, lemon & lime zest beer) tasted. I also found loads of dried strawberries (containing no sulphites) massively discounted in a shop. I put all these things together & a Berliner wiesse was formulated with half the brew being made with Strawberries & half with lemon.
