1. Sager + Wilde View this photo on Instagram Sagar and Wilde is sheer perfection: friendly staff, an extensive and inexpensive wine list, and toasties for days. With a new venue recently opened on Paradise Row, this Hackney peach now has more space than ever. 2. Noble Rot Noble Rot Noble Rot is likely the trendiest wine bar you'll ever encounter. It's tucked off a Bloomsbury side street! It's got its own food magazine! It's got a great restaurant attached! And it boldly declares Chardonnay to be the world's best white wine. What more could you want? 3. Gordon's Wine Bar Flickr: olenkaolja / Via Creative Commons Gordon's is a London classic for a reason. Romantic and low-lit, a city-centre location, it was founded in 1890. It's also got a cracking cheese selection to tide you over while you sip. 4. Bubbledogs View this photo on Instagram A restaurant the specialises in hot dogs and champagne might sound ludicrous. And it kind of is, but in the best way. If you're going to splash out, do it right. And if you're not sure where to start when selecting champagne, then why not take their quiz. 5. Vinoteca Vinoteca Vinoteca is a classic choice, with locations in King's Cross, Soho, Farringdon, Marylebone and Chiswick. But it's the Chiswick branch you should keep on eye on. Their Sunday feasts series of events includes unlimited free pour wine. Find out more here. 6. Brasserie Zedel Ailbhe Malone The Bar Americain at Zedel may be known for its mixed drinks, but they do a great line in wine by the glass. I can recommend it for having a quiet drink with your book. 7. Antidote Ailbhe Malone This charming French wine bar is just off bustling Carnaby Street, but will make you feel like you're lounging on the Marais. Their house rose is dazzlingly good. 8. Bouverie Road Wine Bar View this photo on Instagram This cave is underneath the Stoke Newington Tea House, and is a quiet oasis from the pints and Sunday roasts upstairs. They've got an especially good sparkling wine selection. 9. Humble Grape View this photo on Instagram This neat wine bar is a recent launch from wine merchants Humble Grape. Which means they know their stock inside out. Though the Fleet Street location may be a little ~ City ~ for some, they sweeten the deal on Mondays: You can drink in for the retail bottle price. 10. Pall Mall Fine Wine View this photo on Instagram Pall Mall fine wine is a hidden treasure in theatreland. Forget about trying to slot in a prix fixe – instead share a meat and cheeseboard with a fine Pinot Noir. It's also a perfect location for a quiet solo drink – and I speak from experience. 11. Vivat Bacchus View this photo on Instagram With branches in Holborn and Southwark, this wine bar focuses on South African wines. The Holborn branch is especially nice for a quiet drink with your book. Once more, I speak from experience. 12. 40 Maltby Street View this photo on Instagram 40 Maltby Street is run by Gergovie Wines – wine merchants who work with "a new generation of winemakers eschewing chemical pesticides and fertilisers". So if you're into organic wines, this is the place for you. And the reviews are impeccable. 13. York & Albany York & Albany If you're having trouble convincing your friends to go to a wine bar, then why not tempt them outside with a Wine Terrace? A glass of cool white in the sunshine, just by Regent's Park? Don't mind if I do. 14. L'Entrepot L'Entrepot The ever-reliable Borough Wines are behind this local Hackney restaurant. Their ethos is simple: a small menu that changes often. And the list of wines by the glass is endless (there are 30!) What more could you want? 15. St Pancras Grand Champagne Bar Searcy's Well, if you're going to travel, you may as well travel in style.
