Coca-Cola has been named Ireland's biggest selling brand for a 14th year in a row.
The latest 'Top 100 Brands' list by Checkout magazine and Nielsen also show other Irish favourites on top.
Brennans bread (3rd), Avonmore (4th), and Tayto (5th) all make the top five.
Other brands making headway in this year's list include health-bar brand Fulfil, which climbs from 68th place in 2017 to 49th this year.
Crisp brand O'Donnells moves up 19 places from last year to 77th.
Keogh's Crisps is another popular Irish brand, and is one of three new entries this year, joining the Top 100 in the 96th position.

Since 2012, the Keogh family has seen their crisps gain a strong share of the overall crisp and snack market.
Checkout says: "The Keogh's Farm crisps business has been growing by double digit figures annually, making it the fastest growing and only Irish-owned crisp brand in an extremely competitive market that features dominant international players."
The Checkout Top 100 Brands is based on branded value sales across the Irish grocery sector.
In compiling the report, Nielsen measures the sales performance of over 6,500 brands from over 200 product classes.
'Significant growth'
Maev Martin is editor of Checkout magazine: "What we are seeing in this year's Top 100 Brands ranking is an overall trend of steady growth for many FMCG brands, and some significant growth for others.
"Twenty-six brands have scored an all-time high in 2018's rankings, and a number of Irish brands are featured in this select group."
Brands achieving their best position to date include Ballygowan, Dairygold, Kinder, Hunky Dorys, Keeling's, Aptamil, Glenisk, innocent, Lindt, Magnum, Monster, Brady Family, Pepsi, Flahavan's, Fulfil, Cully & Sully, MiWadi, Panadol, Ben & Jerry's, Cadbury Wispa, O'Donnell's, Clonakilty, Green Isle, Keogh's, Cushelle and Nature Valley.
Drinks, chocolate and alcohol
One of the biggest movers in this year's Top 100 is innocent drinks, which ranked 39th in 2017 but soars to a new personal best of 28th this year.
Elsewhere chocolate brand Lindt, which only made its debut in the rankings last year, continues its high scoring - improving on last year's 40th-place ranking by moving up to 31st place.
The biggest mover this year, however, is energy drink Monster - which moves from 64th position to 38th.
Heineken leads the way in the Top 50 Alcohol brands list for the fifth year in a row, while Santa Rita is Ireland's biggest selling wine - topping the Top 20 Wines list.
Smirnoff leads the Top 20 Spirits list, while Heineken is Ireland's top selling beer.
In Pre-Packed Sliced Meat, Brady Family ousts Denny from the top spot to become category leader - while in the Canned Fish category, Irish brand Shines leaps to third position, pushing Picnic and Epicure down to the fourth and fifth spots.
Frozen Chips is also a category containing a break-out Irish star among young companies.
Strong Roots, which ranks third this year, markets itself as a healthy type of frozen food. It also makes a bold play for the number-one position in the Frozen Prepared Vegetable Products category, claiming second place.
"The relative stability of the Top 100 Brands' top-ten membership indicates that well-established and home-made brands are holding their own in the Irish market," Mr Martin adds.
"Despite the continued rise of private label, and legislative changes in relation to packaging and the recent sugar tax, Ireland's best-known and loved brands continue to innovate and thrive."
