P Portland Syrups Grapefruit Tonic Syrup, 12 oz concentrate — bright grapefruit & elderflower, 40% less sugar for cocktails & soda

Portland Syrups Grapefruit Tonic Syrup is a small-batch, 12 oz concentrate that adds bright grapefruit, elderflower and a tempered quinine note to cocktails and sparkling sodas.

This artisanal syrup is hand-brewed in Oregon from seasonally selected whole ingredients and natural sweeteners to deliver layered citrus complexity with 40% less sugar than typical mixers. One 12 oz bottle yields roughly 12 cocktail servings at a richer strength or up to 24 lighter cocktails, and can make nearly a gallon of soda when mixed as directed. It’s designed to be a versatile bar staple—use it as a tonic replacement for gin and vodka drinks, a flavoring syrup for non-alcoholic sodas, or a brightener in creative cocktails that benefit from a balanced bitter edge.

How does this syrup change my Gin & Tonic or Vodka Tonic?

Swap the usual pre-made tonic for this concentrate to introduce fresh grapefruit top notes, floral elderflower midtones and a subtle quinine bitterness that lifts the spirit instead of masking it. Because it’s concentrated, you control the strength and sweetness of each drink.

• Suggested mix: 1 part syrup to 4–6 parts chilled tonic or soda water depending on desired intensity.
• Use 0.5–0.75 oz syrup per 2 oz spirit for a balanced single-serve cocktail.
• Garnish with grapefruit wedge or edible flower to echo the elderflower scent.
• Stronger flavor per serving—good for stirred or built drinks over ice.

Can I make non-alcoholic drinks or soda with it?

Yes—this syrup works as a soda base and a mocktail syrup. Mix it with sparkling water to make a refreshing grapefruit tonic soda, or combine with herbal teas and bitters for layered alcohol-free cocktails.

• Soda ratio: 1 part syrup to 6 parts chilled sparkling water for traditional-strength soda.
• Mocktail idea: 0.75 oz syrup, 2 oz chilled jasmine tea, top with soda, garnish with mint.
• Nearly a gallon of soda can be produced from one bottle when mixed at recommended ratios.
• Low-sugar profile keeps non-alcoholic drinks bright without cloying sweetness.

What flavors and ingredients will I notice?

The syrup layers fresh grapefruit zest and juice with elderflower’s floral lift and a gentle quinine bitterness that provides structure without overwhelming. Natural sweeteners are used to keep sweetness restrained, letting citrus and botanical notes stay prominent.

• Primary notes: ripe grapefruit and bright citrus oils.
• Supporting notes: delicate elderflower aroma and floral midtones.
• Finishing note: a measured quinine bitterness for balance.
• Crafted with whole ingredients in small batches for consistent flavor clarity.

How should I store and use one bottle to maximize servings?

Keep the bottle refrigerated after opening and use within a reasonable period for best freshness. Because the syrup is concentrated, a single 12 oz bottle stretches across many drinks if you measure carefully.

• Unopened shelf life follows label—refrigerate after opening.
• Estimate: 12 stronger cocktails or 12–24 lighter serves per bottle depending on pour size.
• For sodas, mix the recommended 1:6 ratio to yield nearly one gallon of flavored soda.
• Use a jigger or bar spoon to maintain consistent strength and taste.

Who is this for: Portland Syrups Grapefruit Tonic Syrup suits home bartenders, professional mixologists, and anyone building an at-home beverage program who wants a lower-sugar, flavor-forward tonic alternative. It’s ideal for craft cocktail menus, mocktail enthusiasts, and people who prefer to control sweetness and bitterness in every drink.
