Also, a bottle of Beck's or some Bell's Whisky with a mixer will also be 99p.
On the other hand, pints of Bud Light and Stowford Press Apple Cider, to name a couple, will all be available for £1.69.
For those not planning on drinking liquor for the first month of 2023, Wetherspoons also has non-alcoholic drinks for sale, with Beck's Blue also priced at 99p and other low and no-alcohol beers costing as little as £1.49.
Soft drinks and coffee will also only cost 99p too, and coffees come with free refills.
And if you're feeling a little peckish, food is also included in this sale.
Breakfast, which is served until 11.30am each day, includes three meal choices: MOMA porridge for £1.49, Breakfast muffin deal for £1.99, or the breakfast wrap deal for £2.49.
The deals all include hot coffee, tea, or hot chocolate.
However, a 3oz burger with chips and a soft drink will cost £4.49.
Wetherspoons founder Tim Martin noted that other establishments hold sales in January, so he saw this as "the perfect time" to have a sale at the pubs.
"The range of drinks and food on sale in the pub is aimed at suiting a wide variety of tastes. "I believe that the January Sale will prove popular with our customers," Martin said in a statement.
The Wetherspoons pub sale will run until 14 January.
