The shop, at 344 Essex Road, will be opening a different bottle for tasting each day in the run-up to Christmas.
It is also running a Christmas competition, offering a free bottle of Champagne to the customer who corresponds with the day’s date.
The 20th customer on Sunday, 20 December will will the Champagne that day, for example.
The store offers a wide range of craft beers from around the world, small batch spirits, natural, organic and biodynamic wines, and sparkling wine and Champagne - including by the case.
Borough Wines began life as a stall in Borough market in 2002. It has six permanent stores across London in Hackney, Stoke Newington, Dalston, Kensal Rise, Clerkenwell and Shoreditch.
The Shoreditch branch opened in November.
It expects to add an eighth London store to its growing chain with the opening of a branch in Wandsworth in February.
More openings are likely later in the year.
It opened its first venture outside the capital – The Borough Wines, Beers and Books shop in Hastings, East Sussex – at the end of August.
Borough Wines won the Best Independent Wine Merchant of the Year (more than three stores) at the Harpers Wine and Spirits Awards 2015, announced in September.
