Organic Labelling Organic wines are those made without the use of synthetic fertilisers, insecticides and fungicides. All our wines are either SXC certified organic or certified organic in conversion (the 3-year period of practising organic farming in that growing area prior to becoming fully certified) unless otherwise specified. Vegan Wines Almost all of our wines are vegan-friendly. Fining, the process of clarifying wine, often uses animal products such as gelatin or egg whites - at Tamburlaine our fining is done using plant based ingredients such as legumes. The only wines in our range that are not vegan friendly are the Wine Lovers Scarlett Bubbles and dessert liqueurs. Preservative Free/No Added Sulphur wines While our general winemaking practices use as little sulphur as possible, only those clearly marked as "No added sulphur" or "No added preservatives" are free of added preservatives. Preservatives are an essential part of keeping wine from spoiling during ageing and are safe when consumed in moderation, for those without pre-existing allergies or sensitivity. All such labels are clearly displayed on our bottles' packaging and website product listings, but feel free to contact us with any further questions you might have.
