Customers visiting any site across the 52-strong estate can choose from more than 30 flavour shots, including white chocolate, bubblegum, black cherry sour, pear drop, and peanut butter & jelly, which are made from using triple-distilled vodka.
Revolution Bars Group commercial director Myles Doran outlined how many old, round £1 coins are in customers' savings and urged them to check their furniture.
Checking the sofa
He said: “We understand there’s nearly £500m worth of old coins stored in piggy banks or savings jars around the UK.
“With the old pound coin fast running out of circulation, we are asking guests to exchange their old change for one of our Handcrafted Flavours range. It’s time to check the sofa.”
From Monday 16 October the old, round £1 coin will no longer be legal tender and will be replaced for the first time in more than 30 years because of its vulnerability to counterfeiters.
The new coin, which has a number of hi-tech features, is being introduced to make it harder for counterfeiters to copy.
Pubs will be under no obligation to accept the round £1 coin from customers from that date and should not distribute the round £1 coin.
Earlier this year (May), the paper £5 notes featuring Elizabeth Fry ceased to be legal tender. The new polymer note was issued on 13 September 2016, featuring Winston Churchill.
On 14 September this year, the new polymer £10 note was put into circulation, featuring Jane Austin. The £10 paper notes are still legal tender but will go out of circulation in spring 2018.
A polymer £20 note, featuring the artist JMW Turner, will be launched in 2020. There are currently no plans to replace the £50 note and the Bank of England has stayed tight-lipped about it, saying it will announce the material for future £50 notes in due course.
