Copenhagen Sparkling Tea Company make three AF sparkling teas and BLÅ (meaning blue in Danish) is the closest to a sparkling white wine substitute. It's built from a blend of jasmine and Darjeeling black teas alongside white and green teas, with organic grape juice and lemon juice for body and a touch of natural sweetness. All ingredients are certified organic. The approach is genuinely different from most AF wine alternatives that lean on grape-based products. Here, tea is the primary ingredient and the backbone of the flavour. The carbonation is deliberately wine-like — fine bubbles, 5 bars of pressure — rather than beer-fizzy. The palate has honey, guava and jasmine character with enough complexity to hold interest across a glass. At 20 calories per 100ml and 5g sugar it's comparable to a dry sparkling wine in calorie terms. Vegan, gluten-free, organic. Served in a 75cl bottle at the table it reads credibly as a wine alternative for guests who aren't drinking. Priced at a premium; you're paying for the category as much as the product.
